Abstract

Typically, organic polymers cannot withstand temperatures higher than 200°C. Some of the recently developed organic polymers which are very expensive can withstand about 400°C. The inorganic matrix investigated in a recent research program at Rutgers University can withstand more than 1000°C. In addition, this matrix protects carbon fabric from oxidizing and enhances the temperature resistance of these fabrics. As a result, the carbon composite made with this matrix retains considerable strength even at 1000°C. The matrix is non combustible, and does not release any fumes when exposed to high temperatures. The results presented in this paper include strengths in tension, flexure, and shear. The composites were made using 0/90 fabric orientations and a hand lay-up vacuum bagging technique. The fiber volume content is around 50 percent. Shear and flexural strengths were also obtained after exposing the composite to temperatures varying from 200 to 1000°C. The tensile, flexural, and shear strengths were 327, 245, and 14 MPa respectively for virgin samples. Shear strengths dropped to 5.6 MPa after exposure to 1000°C. The composite retains 63 percent of it's flexural strength after exposure to 800°C.
