Abstract:

An exploratory research investigation to determine the feasibility of producing glass fibers which retain useful properties at temperatures up to 2500 F resulted in the development of fibers which had a strength of 210,000 psi at 1800 F, an elastic modulus of 12.8 x 10 to the 6th power psi at room temperature, and a specific gravity of 2.53. A program to improve the strength properties of laminates made from the high modulus glass developed in Supplement I of the contract resulted in laminates which had wet strengths at least equivalent to similar E glass laminates and an increase of 34 per cent in wet flexural modulus. A program to develop unidirectional, non-woven, preimpregnated reinforcement which would produce laminates having very high strength yielded laminates which had a dry flexural strength of 265,000 psi and a dry flexural modulus of 7.81 x 10 to the 6th power psi.
