Abstract:
1. A high impact strength, elastic laminate system for enhancing impact resistant properties of a laminate structure, said laminate system comprising: a first outer layer; a second outer layer; at least two inner plies placed between the first and second outer layers, said inner plies are substantially sinusoidal in cross-section and having at least one apex, and at least one planar trough section; at least one dissipating element between said inner plies and juxtaposed to said inner plies, said dissipating element being configured to dissipate and redirect randomly directed local loading applied to at least one of said two outer layers, to tensile loading directed in longitudinal direction (tensile) of said inner plies, said dissipating element is an expanded metal mesh having a sheet featuring a plurality of planar sections, and a plurality of openings each being defined by an angularly displaced portion of said sheet; and a polymer matrix in between said first and second outer layers, and said first and second inner plies; said polymer matrix arranged to occupy all the volume not taken up by, and in between the said two outer layers, said at least two inner plies, and said at least one dissipating element; wherein said apex of a first of said inner plies being adjacent to and contacting said first outer layer, and said apex of a second of said inner plies being received in one of said openings of said dissipating elements; wherein each of said planar trough sections of said first of said inner plies contacting at least one of said planar sections of said dissipating element, and each of said planar trough sections of said second of said inner plies contacting said second outer layer.
