Abstract:
The tensile and flexural properties were determined for the resin obtained from the diglycidyl ether of bisphenol A and 6.5 pph of trimethoxyboroxine. The resin has high ultimate flexural and tensile strengths about 5 of the 76 F flexural strength was retained at 300 F. This cured resin should be usable in three-layer canopies at skin temperatures up to 350 F. maximum thermal rigidity was obtained from the hexahydrophthalic anhydride - vinylcyclohexene dioxide resins at a ratio of 0.7 to 0.8 mol anhydride per mol equivalent epoxide. This resin should structurally resist skin temperatures up to 450 F in three-layer composite canopies. A film-forming mold release agent was developed for releasing epoxide resins cast in plate glass molds. Castings of epoxide resins made in the coated plate glass molds had excellent optical properties. The syntheses of novel epoxide resins based on two bicyclic 2.2.1 heptane rings with three different types of connecting groups, a carbonate, an ester, and an ether are discussed. Author
