Corporate Author(s): Owens-Corning Fiberglas Corp Granville OH
Laboratory: Materials Central
Date of Publication: 1960-12

Contract: AF 33(616)-5802
DoD Project: 7340
DoD Task: 73400
Identifier: AD0490475
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 110,000 psi at 1800°F, an elastic modulus of 12.8 x 106 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 106 psi.
