3.4.2.7 Reinforces Plastics and Composites

Reinforced plastics and composites generally utilize thermoset plastics, and occasionally thermoplastics, as a matrix. Reinforcing fibers of glass, mineral, carbon and Aramid are added to increase strength and stiffness. These materials are well established in applications where low weight is essential and increased cost can be tolerated, such as aerospace applications.

Regardless of the reinforcing fibers used, the operating temperature range of reinforced plastics and composites is limited by the polymer matrix materials. The effects of temperature within their operating ranges are complex compared with forging alloys.

Forgings offer advantages of lower cost and higher production rates. The mechanical properties of forgings, even in advanced aerospace applications, are better documented so that performance is more predictable. Forging materials outperform composites in almost all physical and mechanical properties, especially impact toughness, fracture toughness and compression strength.
