Reinforced laminate with elastomeric tie layer

A multi-layer reinforced laminate comprising

• a first outer layer of thermoplastic;
• a second outer layer of thermoplastic;
• a middle layer of thermoplastic;
• a first reinforcing grid disposed between the first outer layer and middle layer;
• a second reinforcing grid disposed between the second outer layer and middle layer;
• a first tie layer of elastomeric material disposed between the first outer layer and middle layer holding the first reinforcing grid but allowing slippage of the first reinforcing grid in the tie layer upon tensile loading of the reinforced laminate;
• a second tie layer of elastomeric material disposed between the second outer layer and middle layer holding the second reinforcing grid but allowing slippage of the second reinforcing grid in the second tie layer upon tensile loading of the reinforced laminate;
• and
• wherein the first outer layer, first tie layer with reinforcing grid, middle layer, second tie layer with reinforcing grid and outer layer are laminated together to form a multi-layer reinforced laminate.

A reinforced laminate produced by a method, comprising:

• 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.
