Rock West Composites Delivers Panels for 500-Watt Arrays to Astro Digital for their Higher-Power Buses This month Rock West Composites delivered panels for Astro Digital’s new 500-Watt arrays to support higher power versions of Astro Digital’s Corvus buses. RWC built the sandwich panels from trace/lead integrated skins that allowed for direct integration with solar cells, saving weight and integration time for the customer.
San Diego, CA (PRWEB) June 27, 2024 – Rock West Composites (RWC) announces the delivery this month of panels for Astro Digital’s new 500-Watt arrays to support higher power versions of their Corvus buses. RWC teamed with Astro Digital to fabricate solar array substrate (SAS) panels with a unique integrated design to save volume and weight. These panels are being integrated into space vehicles, the first of which is scheduled to launch in October.
These SAS panels are unique in that RWC built the sandwich panels from trace/lead integrated skins that allowed for direct integration with solar cells. This reduced total weight and shortened the integration time. The customer furnished the G10 (fiberglass) skins that already had the integrated copper traces. RWC used specialized tooling to align the face skins on the aluminum honeycomb core to keep the traces in the right location during fabrication of the approximately 2’ x 2’ structures.
Jeremy Senne, Space Segment Director, said, “This is a great example of how we can help our customers solve their problems in innovative ways. It was a tooling and machining challenge to work with their pre-integrated skins, but our experience on other precision programs enabled successful fabrication.”

FOR IMMEDIATE RELEASE
Rock West Composites Delivers to Purdue University
the Barrel Timing Layer Tracker Support Tube for CERN’s Large Hadron Collider
This month Rock West Composites delivered a large, high-precision, carbon fiber and honeycomb core tube to Purdue University. The structure is the Barrel Timing Layer Tracker Support Tube that is part of an upgrade to CERN’s Compact Muon Solenoid (CMS), which is a general-purpose detector at the Large Hadron Collider.
San Diego, CA (PRWEB) March 9, 2024 – Rock West Composites (RWC) announces the delivery of the Barrel Timing Layer (BTL) Tracker Support Tube to Purdue University this month. This large carbon fiber sandwich structure destined for CERN was designed by a joint team from Purdue University, led by Dr. Andy Jung and Dr. Ben Denos, and RWC, led by John Marks. The collaborative effort met key performance parameters using the most cost-effective design. The hardware RWC delivered will be integrated with instrumentation from Purdue prior to delivery to CERN.
CERN is the world’s leading laboratory for particle physics located near Geneva, Switzerland. The carbon fiber tube supports the heart of the upgraded CMS detector, a “camera” with more than a billion pixels to record proton-proton collisions at the highest ever-made energies and unprecedented resolution. In a few years, once fully commissioned, the upgraded CMS detector is expected to collect 10 times the data recorded so far in the hunt for new particles and aims to understand the origins of the Universe.
Tube under manufacture and inspection
The BTL Tracker Support Tube had to be manufactured from materials with extremely low radiation resistance, have a precise circular cylinder structure, be very strong and stiff, and meet an accelerated delivery schedule. Because the final tube had such challenging requirements, traditional tooling or manufacturing approaches would have been unaffordable. Innovative techniques were used, starting with the manufacture of curved, solid laminate arc segments rather than a full cylinder. Precision machined arc segment stiffeners help hold the arcs to strict dimensions once assembled. Low coefficients of thermal expansion are maintained in all 3 directions: radially, circumferentially, and along the length of the tube.
Completed hardware with the tooling used for manufacture
Prior to making the full-scale tube, RWC built a full diameter but much shorter version of the part as a technology demonstrator. RWC was presented with an Industry Gold Award from CERN in 2022 for this effort, and ultimately won the program from Purdue for the full-size hardware due to the success of the demonstration model and its affordability.
The delivered hardware is 5.3-meters long by 2.4-meters in diameter. It is constructed of ultra-high-modulus prepreg and Nomex honeycomb core made with PMT-F6 cyanate ester resin. There are 1680 metallic inserts made of solid carbon epoxy, titanium and stainless steel; and it includes two 110 MSI carbon fiber (K13916/ F6) rails to support scientific instruments. Surface accuracy requirements were tested to 2.4mm cylindricity inhouse before shipment.

John Marks, VP of Product Development, said, “We were excited to take on this challenging program and to know that we will be contributing to the advancement of humanity’s understanding the fundamental construct of matter. Our work on the demonstration model and final hardware pushed our team’s technical skills to the limit, and we couldn’t be prouder of their performance on this program.”

Rock West Composites’ Components Are on Intuitive Machines’ IM-1 Mission to the Moon
Supporting the commercial space race to the Moon, Rock West Composites is proud to have provided multiple configurations of struts to Intuitive Machines for incorporation into its Nova-C lunar lander named Odysseus, which launched last week. The struts met challenging surface profile and straightness requirements for both interior and exterior dimensions, were integrated with bonded fittings, and were pull-tested in-house before delivery.
San Diego, CA (PRWEB) February 21, 2023 – Rock West Composites (RWC) provided hardware to Intuitive Machines for incorporation into its recently launched Nova-C lunar lander, Odysseus. Intuitive Machines’ IM-1 Mission is sending its lander to the Moon as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative and Artemis campaign. RWC delivered multiple configurations of machined and tested struts with bonded fittings. The struts included both circular cross-section tubes with and without bonded titanium fittings, and rectangular tubes with a tooled surface on both the inside and outside face.

The RWC-provided struts were primarily constructed of HM63/PMT-F6 unidirectional prepreg with 0.010” and tighter surface profile and straightness requirements. The rectangular tubes were especially challenging due to the tooled surface requirement on both the interior and exterior with a tight surface profile requirement on both sides to allow for next-level assembly tolerances. The hardware was build-to-print, but RWC provided input on the final design for manufacturability and requirements compliance. The struts with bonded fittings were pull-tested in-house at RWC prior to final integration at Intuitive Machines.
RWC Strut Assemblies
“We are honored to support our commercial customers in this race to the Moon and ultimately a sustained human presence there,” said Jeremy Senne, RWC’s Space Segment Director. “Our precision composite components can give our customers the performance they need to succeed in this high-risk and clearly challenging business.”

Rock West Composites Ships First Set of
Solar Array Substrate/Back-Up Structure Assemblies for the DiskSat Program
Rock West Composites announces that this month it shipped the first four solar array substrate/back-up structure assemblies to The Aerospace Corporation in support of the DiskSat Program. The company, whose engineering team consulted on the substrate and assembly design, used their space-grade, off-the-shelf STRATO™ panels to reduce cost and lead times, plus met positional tolerances of 0.010”-0.020” without costly assembly fixtures.
San Diego, CA (PRWEB) January 31, 2023 – Rock West Composites (RWC) delivered four combination solar array substrate/back-up structure assemblies to The Aerospace Corporation in support of the DiskSat Program this month. DiskSat is a NASA-funded technology demonstration program that seeks to verify the performance and deployment method of this new small-spacecraft platform. The disk-shaped satellite design has the potential to revolutionize smaller space missions through its high power, large aperture form factor that fits in the circular cross-section of a rocket fairing. By using its own off-the-shelf, space-grade STRATO products, RWC was able to significantly reduce lead time and cost, while helping define structural properties to support the mission’s innovations. If successful, follow-on missions are possible, and other prime contractors may look to use a similar form factor for volumetric and weight efficiencies.
Set of four DiskSat Assemblies
Providing additional services for this build-to-print program, the RWC engineering team consulted on the design including layup, material selection, insert design, bonding methods, and manufacturing strategy. RWC used its own product, the STRATOSubstrate™ LEO class, to ensure a cost-effective solar array substrate. The team used an insert design that allowed for self-fixturing to a tight tolerance, avoiding a costly assembly fixture. The tolerances on the in-plane and out-of-plane inserts match to a global datum scheme, and tolerances were on the order of 0.010-0.020” positional.
The use of STRATOSubstrate LEO panel blanks significantly reduced raw material and blank lead time. STRATOSubstrate LEO class panels use HR40/NB321 unidirectional prepreg, NB301 film adhesive, perforated aluminum honeycomb core, and 0.002” HN Kapton. The inserts for the deliverable were BR-127 primed aluminum bonded with EA9394. The final assembly measures approximately one meter in diameter and 25 centimeters in thickness.

FOR IMMEDIATE RELEASE
Rock West Composites Is Expanding Its Short Lead Time, Space-Ready STRATO™ Product Line
This month Rock West Composites announces the expansion of its space-grade STRATO product line, which now has two classes created for LEO, GEO and Deep Space applications. These selections of tubes, plates, sandwich panels, and solar array substrates are some of the Space market’s fastest turnaround products with most lead times ranging from two to four weeks.
San Diego, CA (PRWEB) April 11, 2023 – Rock West Composites (RWC) announces the expansion of its STRATO space-grade product line this month. Originally focused on tubes for Lower Earth Orbit (LEO) applications, a secondary line will now include products appropriate for Geosynchronous Equatorial Orbit (GEO) and Deep Space use. STRATO products now include plates, sandwich panels, and solar array substrates for both orbital types.
The STRATO line is designed to provide businesses and government agencies high-quality components commonly needed for spacecraft, but RWC offers dramatically shorter lead times—approximately two to four weeks—than competing providers, and the order can be placed easily online.
The entire STRATO line meets key requirements for space, with properties that include low outgassing, low to zero CTE, high modulus materials, and a wide operational temperature range. RWC can offer significantly reduced lead times because it stocks raw materials such as M55J/PMT-F33 Cyanate Ester and HR40/NB321 Epoxy for its ecommerce business.
The STRATOLeo class is a more cost competitive option for meeting space requirements without the additional high-performance capability typically associated with GEO orbits and Deep Space flights. The STRATOGeo class uses top-of-the-line materials in all cases where performance can’t be compromised. The table below details some of the differences of the product classes.
Each order includes a certificate package with dimensional inspection, material certificates, traceability, and a certificate of conformance from RWC. All products are serialized and traceable. Additional options for some products include full traveler verification, resin content testing, and short beam shear testing.
“Our goal is to make space quality hardware readily available in a cost effective and efficient manner,” said Jeremy Senne, head of RWC’s Space market segment. “Whether it’s a start-up business building cube sats or large prime contractors looking to optimize operations, agile organizations in a rapidly growing industry need high quality solutions quickly. Our hope is to help minimize design and build timelines by standardizing available products.”
