Methods of forming multi-component reinforced composites are described. The methods may include forming a particle-reinforced component and a polymer-containing component where the particle-reinforced component and the polymer-containing component are in contact with one another. The particle reinforced component may be formed by a process that includes providing reactive particles that have a reactive polymerization promoter chemically bonded or coated on the surface of the reactive particles and contacting the reactive particles with a resin solution that includes monomers of a polymer. The polymerization promoter chemically bonded or coated on the surface of the reactive particles may promote the polymerization of the monomers. The resin solution may subsequently be polymerized forming a polymer matrix around the reactive particles.

A ballistic shielding material element is provided formed of molecularly oriented layers of material, such a polyethylene or HDPE that is modified using the application of continuous mechanical tension in combination with alternating heating and cooling cycles. The molecularly oriented planar material may then be used in the creation of ballistic resistant material panels through bias lay-up of subsequent layers. Further, the final multilayer composite may be additionally cured to form a final shape, such as a sheet material for construction or three dimensional shapes such as helmets, shields or custom shapes as needed by the end user. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A component includes at least first and second plastics component parts which are interconnected in a connection zone. A reinforcing element includes at least one wire which bridges the connection zone. The first and second plastics component parts are welded together and/or are fused together in the connection zone. The plastics component parts may be bonded to one another.
