INVESTIGATION OF COMPOSITE STRUCTURES FABRICATED WITH advanced high-STRENGTH, HIGH-MODULUS REINFORCEMENT MATERIALS

Abstract

Methods of making boron-plastic plane isotropic structural composites using boron film reinforcement were developed. Principal objective was to obtain high percentages of boron in the composite and values to 54% by volume were achieved. This resulted in elastic moduli up to 31,000,000 psi and tensile strengths up to 40,000 psi. The two fabrication techniques studies involved: (1) a 1/4 mil polyimide substrate for the boron film; (2) an aluminum substrate which was partially removed.
