Methods for polymer materials

Abstract

A method to produce a polysilazane prepreg can include producing a resin system comprising a blend of polysilazane polymer with silazane oligomer, said oligomer acting as a reactive diluent to tune the resin system to the desired viscosity to use as a prepreg, optionally comprising fillers, said system allowing the processing of polysilazane into ceramic matrix composite parts using suitable manufacturing techniques to process standard polymer composites and to allow the manufacture of composite parts with high temperature resistance wherein the reactive diluent comprises any oligomer of lower viscosity than the polysilazane and capable of reacting with said polysilazane to form a cross linked polymer network. Also provided are composites and articles prepared according to a method in accordance with the disclosed subject matter.
