Rods & Shapes
Stiffness and affordability ◾ Tight tolerances ◾ Wide range of small sizes ◾ Carbon fiber and fiberglass rods cut to order
We carry tons of composite rods in a wide variety of shapes and sizes. From carbon fiber to fiberglass, we strive to have most of what you need available to ship out the next business day. We're also able to cut rods to a variety of lengths. We offer custom composite rods if you aren't able to find what you need off-the-shelf.
What is Pultrusion
If you are not familiar with the pultrusion process, it’s easy to think of it like the extrusion process used for aluminum and plastic. However, instead of squeezing and pressing material through a die, the pultrusion process continuously pulls material. The fibers are pulled from rolls through a heated die while simultaneously being injected with resin. The shape of the die determines the shape of the finished profile. The resin cures as it’s being pulled through the heated die forming a rigid profile with precise dimensions. Since the process continuously pulls fiber and resin through the die, the maximum length is only limited by how long the fiber rolls are and how much space is available for the finished part.
Pultrusion Process Guarantees
There are multiple benefits to the pultrusion process that include the following guarantees:
- Super accurate dimensions
- High fiber volumes
- Smooth surface finish
- Perfectly aligned fibers
- Excellent price/performance ratio
