摘要： This invention relates to a method for preparing a polyimide having good heat-stability and excellent flowability in a molten state.The polymide is prepared by reacting aromatic diamines such as 4,4'-bis(3-aminophenoxy)biphenyl, bis[4-(3-aminophenoxy)phenyl] ketone and bis [4-(3-aminophenoxy)phenyl] sulfone; tetracarboxylic dianhydrides such as pyromellitic dianhydride, 3,3', 4,4'-benzophenonetetracarboxylic dianhydride and bis(3,4-dicarboxyphenyl) ether dianhydride; and dicarboxylic anhydrides such as glutaric anhydride, 1,2-hexanedicarboxylic anhydride, phthalic anhydride and 3,4-benzophenonedicarboxylic anhydride. The molar ratio of aromatic diamine: tetracarboxylic dianhydride: dicarboxylic anhydride is 1:(0.9 to 1.0):(0.001 to 1.0).The invention also relates to polyimide composite materials which are excellent in mechanical strengths and processability. The materials contain the polyimide and fibrous reinforcing materials such as yarn, roving, tow, fabrics, mats and felts of glass fiber, carbon fibers or aromatic polyamide fibers.

摘要： Method and apparatus for manufacturing a sheet-prepreg reinforced with fibers wherein a sheet of fibers such as warp or woven fibers such as fabrics is conveyed between a pair of band belts one of which is coated with a film of thermoplastic resin which has been heated higher than its softening point to enhance resin-impregnating efficiency and prevent the impregnated resin from contacting air. Further, when the sheet of fibers or woven fibers is conveyed in this manner, the molten resin is not maintained on the manufacturing line, thereby preventing it from being deteriorated by heat. The apparatus can be thus kept under operation for a long time and the sheet-prepreg reinforced with the fibers can be made much higher in quality and the deterioration of the impregnated resin can be further delayed.
