OPTIMUM FILAMENT DIAMETER

Abstract

Sea water immersion tests were completed for uncoated and coated large diameter fibers. The protection of the coating retards moisture attack such that 27-day immersion is required before the strength levels off. The strength of uncoated fibers falls much more rapidly and tends to level off at the end of 7 days. Special laminating procedures are required for winding large diameter fibers. It ws determined that winding directly from the bushing was the only method of laminating fibers larger than 0.004 in diameter. NOL rings wound with large diameter fibers are structurally superior to those with conventional fibers. Compressive strengths approaching 300,000 psi composite stress are possible as well as composite modulus greater than 10 to the 7th power psi. (Author)
