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 14 mil polyimide substrate for the boron film 2 an aluminum substrate which was partially removed.
