摘要: Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite materials which increases the positive buoyancy of the composites in water.

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: Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of highly oriented yarns are subjected to a treatment that enhances the surface energy at the yarn surfaces and are coated with a protective coating immediately after the treatment to increase the expected shelf life of the treatment.

摘要: Multilayer composite materials combining a low tenacity nylon fabric with a fabric formed from high tenacity fibers. The fabrics are bonded with a compatibilizing adhesive system that achieves a peel strength of at least 1.5 lbs/inch. The nylon is colored with a camouflage pattern and the high strength fabric is colored with a color that does not stand out relative to the camouflage pattern. The composite materials are used for forming vest covers and plate carrier materials, particularly webless plate carrier materials having slots for hanging modular accessories.

摘要: Hybrid fibrous composite materials incorporating at least two different fabric components and a multicomponent adhesive system for adhering the fabric components together. The adhesive system enhances the bond strength between the fabric components, which would otherwise easily delaminate from each other and peel apart. The components of the adhesive system bond strongly to each other as well as to the fabric elements.

摘要: 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.
