Evaluation of High-Strength-and-Modulus Brittle Materials in Filament and Composite Forms

Source

A program is under way with the broad objective of accurately evaluating new high-strength-and-modulus brittle materials in filament and composite form for application as primary structural materials. Initially, the work has involved laboratory testing of continuous-filament boron. Primary emphasis has been on developing testing procedures for tensile and flexural strength and modulus. Short-term filament tensile strengths have been measured at temperatures up to about 1800 F. Fabrication techniques have been developed for producing small rectangular composite beams with good filament orientation. Loading up to 70 per cent by volume of boron filaments has been obtained. Tests on composites indicate that a high percentage of the filament properties are translated into composite properties.
