Abstract
A composite structural material is prepared by admixing (1) sulfur plasticized by reaction with dicyclopentadiene, or dicyclopentadiene and styrene, (2) asbestos fibers wetted with dipentene and (3) silica flour, maintaining the mixture at about 120 to 150.degree. C for about 0.5 to 5 minutes and casting the resulting product under a pressure of about 500 to 1500 psi. Additional strength is obtained by curing at elevated temperature prior to casting.
