Reactions

Summary

Reaction between diisocyanate and the hydroxyl groups on the surface of carbon fiber oxidized by nitric acid was investigated. It was found that polar solvents were favorable for the reaction. Stronger amines and Ba-laurate catalysts gave good results.

Further, rigid polyurethane foam reinforced by the carbon fiber thus prepared was found to show improved bending properties.
