This document summarizes research on advanced fiber composite materials (AFCM). It discusses various advanced fibers like carbon, glass, ceramic and organic fibers. It describes the production processes and properties of these fibers. The properties discussed include density, modulus, strength, stiffness and thermal expansion coefficient. Composites using these fibers can be used for lightweight and high strength applications in aerospace. The document concludes that AFCM have great potential for aerospace, aircraft and spacecraft due to their improved mechanical properties compared to traditional materials.
