HSHT Fiberglass

Thermally resistant Continuous Fiber for strong parts in high-temperature environments

High Strength High Temperature (HSHT) Fiberglass is defined by two characteristics: high strength (nearly equal to 6061-T6 Aluminum) and strength in high temperatures. Though not as stiff as Continuous Carbon Fiber, Onyx parts reinforced with HSHT are strong at both low and high temperatures. As a result, HSHT reinforcement is best used for parts in high-temperature environments like molds, autoclaves, and others.
