摘要:
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.
摘要:
The invention relates to a material sheet comprising at least one monolayer, wherein at least one monolayer comprises a plurality of drawn unidirectional polymer fibers having a strength of greater than 1.2 GPa, characterised in that the at least one monolayer has a thickness of less than 100 µm and the material sheet comprises a bonding agent of less than 13wt% relative to the total weight of the material sheet.
摘要:
Disclosed are a bulletproof fabric and a method for producing the same that exhibit improved anti-traumaproperty and minimize deterioration in bulletproofness even after use under harsh conditions for a long period of time. The bulletproof fabric includes a fabric comprising at least one high-strength fiber selected from the group consisting of a high molecular weight polyethylene fiber, an aramid fiber, and a polybenzoxazole fiber, and a water repellent layer disposed on the high-strength fiber, wherein the water repellent layer is formed by treating the fabric with a water-repellent agent comprising fluorocarbon and a hardness-enhancing resin, and the hardness-enhancing resin is a polyvinyl acetate resin, a polyester resin, a polyacrylate resin, a melamine resin, or a mixture of two or more thereof.
摘要:
The invention relates to a process to make films and tapes from ultrahigh molecular weight polyethylene (UHMWPE) in the solid state. The films and tapes according to the invention have an improved thickness whereby the coefficient of variation of the thickness of the film of at most 6%.
摘要:
Methods and apparatus are provided for a durable, wear resistant composite fabric. In one exemplary embodiment the composite fabric comprises an outer layer of a woven synthetic fabric, and a backing layer of a woven fabric made from high tenacity fibers. The backing layer may be consolidated with the outer layer.
摘要:
Dense, highly stable, high performance ballistic material comprises at least one woven layer of ballistic grade fiber (preferably a stack of such layers) and at least one nonwoven layer of fabric which is entangled with the woven or unidirectional layer by needle felting. The resulting core material does not require assembly of individual woven layers during subsequent manufacture of ballistic articles and exhibits excellent ballistic performance at low areal densities and thicknesses.
摘要:
The invention relates to an antiballistically effective article which comprises a plurality of fabric layers from fibers having a strength of at least 1100 MPa according to ASTM D-885, at least two groups of zones of different fabric density being present within at least one fabric layer. Zones of a first group have a fabric density according to Walz of 8% to 31% and zones of a second group have a fabric density according to Walz of 32% to 80%.
