Claims27
An article comprising a composite structure comprising a fabric of thermoplastic organic polymer impregnated with a cured, heat resistant polymer, wherein the composite structure has sufficient stiffness to be self supporting and is dimensionally stable up to a temperature of at least about 195° C.
A process for making a composite article with a predetermined shape comprising the steps of:
- a) providing a flat sheet of a fabric comprising a thermoplastic organic polymer;
- b) impregnating the fabric with a liquid precursor to a heat resistant polymer;
- c) inserting the flat sheet into a heated mold to form the sheet into the predetermined shape;
- d) heat curing the liquid precursor to form cured, heat resistant polymer, thereby fixing the composite article in the predetermined shape;
- and
- e) removing the shaped composite article from the mold.
