Hycomp Composites
H310® & H320® Materials

These composite solutions are high temperature, polymer-based materials that are reinforced with glass or carbon fibers. They are used as a replacement for metal due to weight saving properties and eliminating lubrication need in applications with high mechanical requirements. Suited for aviation critical systems such as engine, flight control, landing gear, wheel and braking, applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.

The H310® composite is an aerospace-grade blend of high-temperature golden resin thermoset polymer sheet molding compound (SMC) with one-inch chopped, gold carbon fiber reinforcement. It has the highest strength at temperatures up to 315°C (600°F) and is best for lower to moderate speeds and high loads.


The H320® composite is a blend of high-temperature resin thermoset polymer and one-inch chopped glass fiber reinforced material. More of a thermal insulating material and black in color, it offers good mechanical strength at 315°C (600°F) continuous operating temperature.


As light weight and high strength solutions, these advanced composites can drive down costs and offer as much as 40% reduction over metal and other alternatives in some cases.

Is this Material PFAS-Free*?

  • * PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.
