Other Fibers and Reinforcements

Other reinforcing fibers, of less commercial importance at the present time, include asbestos, ceramic fibers, silicon carbide fibers, whisker 

They have been used extensively in the past in many different applications including RPs. The fibers offer advantages such as excellent/high strength and stifihess, good rigidity, chemical resistance, and particularly fire resistance. However its use has ceased in all but closely controlled applications, following realization of the health hazards associated with it. 

A reinforcing fiber with high strength and modulus with 2.7 density. Primary purpose for this development was for the reinforcement of metal matrix and ceramic matrix composite structures used in advanced aerospace applications by the military. SiC fibers were developed to replace boron fibers in these RPs, where boron had its drawbacks principally degradation of mechanical properties at temperatures greater than 540C (lOOOF) and very high cost.
