Abstract
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.
Claims12
A filament winding process for producing a curved product, preferably an armor product, in which a plurality of reinforcing elements, having a strength of at least 1.6 GPa, is impregnated with a polymer matrix and wound onto a mandrel, whereby 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, and wherein the amount of reinforcing elements is at least 60% of the total mass of the product.
