HyComp® Materials

WearComp® | FibreComp®

H310

H310™

H310 is an aerospace-grade blend of high-temperature resin thermoset polymer sheet molding compound (SMC) with one-inch chopped carbon fiber reinforcement. 

Applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.

HyComp H320

H320™

H320 is a blend of a high temperature thermoset polymer and 1” glass fiber. 

This material is best suited for high temperature heat shields and high temperature electrical insulation applications.

WearComp

WearComp®

WearComp is a blend of a high temperature polymer and 1” chopped carbon fiber.

WearComp is particularly suited to liner and bearing sleeves, and sliding plates subject to high stresses.

FibreComp

FibreComp®

FibreComp uses the same resin system as WearComp, but incorporates milled carbon fiber and graphite for applications that require additional lubricity. 

It is used for applications with high rotational speed and low impact intensity.
