Abstract
3D Nextel™ 720/Mullite composites were fabricated by precursor infiltration pyrolysis method. Influence of the matrix component control, the dense of composite and the treating temperature on the fracture strength of composites was studied. The results indicted that the dense composite were obtained by using the mixture of TEOS(Si(OC2 H5)4) and aluminum-s-butoxide (Al (OC3 H7)3) as precursor through cycle infiltration at relative low temperature(≤ 1200°C).
