ABSTRACT:
A high strength synthetic resin based structural material in which a polymer having coil-like molecules is uniformly mixed with a second polymer having rigid rod-like molecules. This material is made, basically, by dissolving a thermoplastic matrix polymer having coil-like molecules in a suitable solvent, adding thereto thermosetting polymer reactants which then form a prepolymer. The rigid rod prepolymer may then be partially cyclized through heat or by the use of a chemical agent in order to reduce chain conformations. Excess cyclizing agent can then be removed and the mixture can be heated to complete polymerization to produce a high strength structure with rigid rod-like molecules intimately blended with the matrix coil-like molecules.
