摘要:
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.
摘要:
An apparatus and method are provided for evaluating the backface signature of flat panel ballistic resistant composites with accuracy, repeatability and improved correlation to the expected backface signature of shaped ballistic resistant composites in actual field use. The apparatus separates the composite from a clay backing material with a suitable spacer so that the bulk of the backface deformation is inside an air gap space with minimal clay disturbance, thereby eliminating conventional testing error and producing an accurate test result.

摘要:
An impact resistant rigid composite has a plurality of fibrous layers, each of which comprise a network of filaments. The fibrous layers are disposed in a matrix, with elastomeric layer(s) therebetween. Prior to curing of the matrix, successive fibrous layers exhibit therebetween a peel resistance of at least about 3 g/cm. The composite has high rigidity combined with superior ballistic properties. When bonded at one or both surfaces to a hard plate selected from the group consisting of metals and ceramics, the composite affords increased protection against armor piercing projectiles.
