Prepreg Tow

TCR™ Towpregs feature a patented thermoset resin system, storable at room temperature, that can be used with virtually any continuous fiber reinforcement. TCR™ Towpregs are designed for high throughput (up to 900 ft or 275 m per minute) for filament winding applications. Tow can be impregnated utilizing 6K to 60K standard modulus to high modulus carbon fibers as well as glass, basalt and aramid with equivalent cross sections.

TCR resins are matched with industry fibers to provide optimal performance. Each fiber has unique properties and may require a specific resin to achieve maximum performance.

From high-performance rocket-motor cases to the highest quality commercial pressure cylinders, TCR™ Towpregs are the material of choice for pressure vessels and are used in a variety of markets including aerospace, defense, industrial, infrastructure, recreation and marine.
