Abstract:

This report presents strength properties of plastic laminates reinforced with glass fibers and designed to endure elevated temperatures. In previous reports, data have been presented on such laminated materials as silicone-glass, phenolic-glass, epoxy-glass, and phenyl-silane. The glass fibers used in the previous work were E glass, but S glass fibers have shown promise and are being checked. The S glass involved here was in a phenyl-silane resin laminate of Narmco 534 resin and 181-S994-Z6040 glass fabric. As previously, strength and elastic properties are reported. In general, the data show that the strength properties decrease with increases in temperature, as expected. Effects are described on individual strength properties with changes in temperature between 80 and 1,000 F. and of exposure periods between 0.05 and 1,000 hrs. Data are presented in tables and curves so the magnitude of various effects may be judgedseparately. Stiffness of this S glass-reinforced laminate was generally greater than that of a similar laminate reinforced with E glass. Tensile and flexural strengths were also greater for this laminate than for one with E glass.
