Abstract:

When the diglycidyl ether of bisphenol-A reacts with m-phenylene diamine, the resulting plastic strongly binds glass filaments, and good quality filament-wound objects may be produced from these materials. Two additional plastics which are suitable for this application have been produced from curing agents which are molecularly similar to m-phenyene diamine. One of these curing agents, m-aminobenzylamine, has one aliphatic amino group, and the other, m-xylylene diamine, has two aliphatic amino groups. Tensile and elongtion properties are compared for the plastics produced from these amines and the diglycidyl ether of disphenol-A. The plastic produced from m-aminobenzylamine has outstanding properties and pressure vessels produced using it are believed to be superior to those containing -phenylene diamine.
