摘要:
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.
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:
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.
摘要:
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties and retained or improved ballistic penetration resistance properties. The composites are formed from high tenacity fibers having a tenacity of at least about 33 g/denier at ambient room temperature after being modified by a plasma treatment or by a corona treatment, without tenacity loss due to said treatments.
摘要:
Methods for modifying high tenacity fibers without reducing the physical strength properties of the fibers. More particularly, methods for modifying fibers with a plasma treatment or a corona treatment without reducing the physical strength properties of the fibers.
摘要:
Methods for producing composites useful for the formation of both soft and hard armor. More particularly, methods for the production of ballistic resistant fibrous composites having improved ballistic resistance properties, including low backface signature. The methods employ fiber surface treatments to improve the anchorage of substances applied onto fiber surfaces, achieving a low delamination tendency and corresponding benefits.
摘要:
Ballistic resistant composites having improved durability. More particularly ballistic resistant composites including a protective thermoplastic overlay that enhances composite abrasion resistance while also permitting exploitation of the properties of an underlying binder system.
