FIBER REINFORCED COMPOSITES

摘要

Compositions comprising elastomeric polyurethane prepolymers comprisingthe reaction product of at least one diisocyanate selected from the group consisting of p-phenylene diisocyanate, m-phenylene diisocyanate, 1,4-cyclohexyl diisocyanate, tetramethylxylyl diisocyanate and dimethylphenyl diisocyanate and at least one polyol or polythiol characterized by the presence of two hydroxyl or thiol groups or one hydroxy and one thiol group; a monomeric diol or dithiol curing agent and vein forcing fiber are especially useful for preparing fiber-reinforced composite structures, especially for dyanimic applications.
