Abstract:
Highly uniform woven fibrous structures formed from fibrous tapes, wherein the tapes constitute the warp and weft tapes of a woven fabric. The individual fibrous tapes may be woven or non-woven, and may be formed as narrow tapes or may be cut from a wider fabric web.
Abstract:
A process for forming defect-free fibrous composite materials. More particularly, a process for forming blister-free fibrous composites without having to actively monitor or control blister formation during molding of a stack of plies, and to blister-free composite materials fabricated therefrom. Fibrous plies are coated with a dry, particulate binder without impregnating the plies with the binder. Gaps between fibers/tapes allow air to diffuse out of the stack without affecting the binder coating, thereby avoiding blister formation.
Abstract:
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced flexural properties, which correlates to low composite backface signature. The composites are useful for the production of hard armor articles, including helmet armor.
Abstract:
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.
Abstract:
An apparatus and method 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.
Abstract:
Ballistic resistant materials and articles formed from fiber/tape plies that incorporate multiple different fiber or tape types within a single ply. The different fiber or tape types are physically dissimilar but may be chemically different or substantially chemically similar.
