Abstract
The present invention provides a composite material comprised of a matrix polymer and a reinforcing polymer, called a rigid rod polymer, which is well dispersed in the matrix polymer. This material displays enhanced mechanical properties. The matrix polymer is preferably cured resin, preferably epoxy resin. The rigid rod polymer may be made from polyazomethines, polyimides or polycarbodimides, or mixtures thereof. Preferably, the reinforcing polymer is a polyazomethine. The invention also relates to a method for making the composite material. The composite material is preferably made by first dissolving the rigid rod polymer precursors in the matrix polymer precursors, then polymerizing the rigid rod polymer precursors in-situ and then polymerizing the matrix polymer precursors, in-situ. Alternatively, the rigid rod polymer precursors may be polymerized in-situ simultaneously with the polymerization of the matrix polymer precursors.
