Abstract

A method of making a reinforced laminate, including the steps of placing a reinforcing grid on a first outer sheet of thermoplastic, preparing an elastomeric material capable of forming a tie layer between two sheets of thermoplastic, and laminating a second outer sheet of thermoplastic to the first sheet of thermoplastic and the reinforcing grid with the tie layer of elastomeric material therebetween, whereby the reinforcing grid is held by the elastomeric tie layer in between the first outer sheet of thermoplastic and the second outer sheet of thermoplastic, and the reinforcing grid being displaceable within the elastomeric tie layer. A reinforced laminate, including a first outer layer of thermoplastic, a second outer layer of thermoplastic, a reinforcing grid disposed between the first outer layer and the second outer layer, a tie layer of elastomeric material disposed between the first outer layer and the second outer layer arranged to hold the reinforcing grid but allow slippage of the reinforcing grid in the tie layer upon tensile loading of the reinforced laminate, and wherein the first outer layer, the second outer layer, the reinforcing grid, and the tie layer are laminated together to form a reinforced laminate.
