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.
Claims15
A filament winding process for producing a curved product comprising:
- winding a plurality of reinforcing elements having a strength of at least 1.6 GPa onto a mandrel to form a fiber structure, and
- impregnating the fiber structure with a polymer matrix, wherein
- the reinforcing elements are present in an amount of at least 60% of the total mass of the product.
