Latest Patents

Darleen A Druyun holds a patent for a "Low pressure process for continuous fiber reinforced polyamic acid resin." This patent describes a low-pressure method for preparing a well-consolidated polyimide composite laminate. The process involves forming prepreg plies from unidirectional fibers and a polyamic acid resin solution. Molding stops are strategically placed at the sides of a matched metal die mold. The prepreg plies are cut shorter than the length of the mold in the in-plane lateral direction and stacked between the molding stops to a height exceeding that of the stops. The plies are then compressed to the height of the stops and heated to allow volatiles to escape and initiate the imidization reaction. After removing the stops from the mold, the heat is increased, and a pressure of 0-500 p.s.i. is applied to complete the imidization reaction. The heat and pressure are further increased to form a consolidated polyimide composite laminate.
