STABILIZABLE PREFORM PRECURSORS AND STABILIZED PREFORMS FOR COMPOSITE MATERIALS AND PROCESSES FOR STABILIZING AND DEBULKING PREFORMS.

摘要

A STABILIZABLE PREFORM PRECURSOR FOR COMPOSITES IS PROVIDED. THE PREFORM PRECURSOR HAS AT LEAST ONE LAYER OF A STRUCTURAL FABRIC COMPRISED OF REINFORCING FIBERS WHEREIN AT LEAST ONE OF THE LAYER(S) OF STRUCTURAL FABRIC HAS INTEGRATED THEREIN ONE OR MORE STABILIZING FIBER(S) THAT DISSOLVES AT A DISSOLUTION TEMPERATURE IN A RESIN FOR INFUSING INTO THE STRUCTURAL FABRIC TO MAKE THE COMPOSITE. THE STABILIZING FIBER STABILIZES THE STABILIZABLE PREFORM PRECURSOR WHEN THE STABILIZABLE PREFORM PRECURSOR IS SUBJECTED TO AN ELEVATED TEMPERATURE.
