A ballistic resistant panel assembly which includes a plurality of ballistic resistant plies positioned in a stack, wherein at least one ply of the plurality of ballistic resistant plies includes a larger dimension than other ballistic resistant plies positioned within the stack. The at least one ply comprises a bend and at least a portion of the bend is spaced apart from a peripheral edge of the at least one ply. Additionally, a method for assembling a ballistic resistant panel assembly is provided.

A composite armor includes a ceramic substrate defining a frontside opposite a backside, where a thickness is defined extending between the frontside and the backside. A first tension-wrapped thermoplastic composite overwind is wrapped around the ceramic substrate about the frontside and backside. A first portion of the first overwind overlaps a second portion of the first overwind. The first and second portions of the first overwind are fixedly attached to one another utilizing a first localized heating. The first overwind includes a first tensile pretension. A backing is disposed about the backside of the ceramic substrate attached to the first overwind. The ceramic substrate has a higher modulus of elasticity in comparison to the overwind. The first overwind has a higher modulus of elasticity in comparison to the backing.

The invention relates to a preformed sheet, comprising a network of polyethylene fibers having a tensile strength of at least 1.5 GPa, impregnated with at least 10% of a plastic wherein the plastic material is an acrylic based thermoplastic material with a glass transition temperature of at least 25? C. The invention further relates to an assembly of at least two preformed sheets and to a ballistic resistant article comprising at least one assembly.

A joint member (100) includes a metal component (12) and a composite component (14) which are joined by a joint (10) formed at a non-planar joint interface (18) defined by a textured surface portion (28) of the metal component (12) and a solidified melted area (24) of the composite component (14). The solidified melted area (24) adjacent to the joint interface (18) is characterized by a plurality of non-contiguous solidification boundaries (22) and a non-contiguous dispersion of porosity (16). A method includes forming a textured surface portion (28) on the metal component (12), pressing the textured surface portion (28) into the surface of the composite component (14) to form depressions (32) in the composite component (14), such that a joint interface (18) is defined by the surfaces of the textured surface portion (28) and the composite depressions (32), heating the joint interface (18) to melt an area of the composite component (14) adjacent to the joint interface (18), and solidifying the melted area (24) to the form a joint (10) at the joint interface (18).

The invention relates to a curved product, and in particular an armor product. The armor product is produced by a filament winding process in which a plurality of reinforcing elements in the form of fibers and/or tapes are impregnated with a polymer matrix and wound onto a mandrel. The polymer matrix comprises a solution and/or dispersion of a polymer in a carrier fluid, which carrier fluid is at least partly evaporated during and/or after winding. The armor product comprises a high amount of reinforcing elements with respect to the total mass of the product.
