Abstract
A method of forming a lightweight, contoured, structurally stable, self-supporting laminate comprises laying down, in succession, a finish lamina, a first heat activated adhesive, a first thermoformable scrim lamina, a second heat activated adhesive, a high density polymeric foam lamina, a third heat activated adhesive, and a second thermoformable scrim lamina thereby forming an unbonded laminate. This unbonded laminate is then uniformly heated in an oven to a temperature sufficient to make the adhesives bondable thereby forming a heated, substantially unbonded laminate. This heated, substantially unbonded laminate is then quickly transferred to a contoured die press and permanently bonded and formed, under pressure. The laminate is permanently bonded utilizing the residual heat in the laminate to form a contoured, structurally stable, self-supporting, impact resistant laminate.
