Half Round Solid Rods
Stiffness & affordability ◾Tight tolerances ◾ Great for hobbyists and structural reinforcements
Our half round pultruded rods not only offer high stiffness, but they also provide a convenient flat surface for bonding or mounting. Pultruded products perform incredibly well in bending and tension (pulling) applications since all the fibers are oriented along the length of the tube (or rod). They do not, however, perform well in other loading scenarios such as torque and crushing. These parts are made by pulled fibers through a shaped die while simultaneously injected with resin to create the required profile. Note: We do not recommend pultruded tubing or rod in applications such as drone or UAV motor (boom) arms.
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
