<p>The present invention relates to wood that is reinforced with a fiber-reinforced thermoplastic composite that contains a plurality of substantially parallel continuous fibers impregnated with thermoplastic polymer having the following structural units:where Z is S or O, and Z' is S, O, N-alkyl or NH The invention is useful in a variety of applications including glue-laminated structures, laminated veneer lumber, reinforced I-beams, parallel strand lumber, reinforced particle board, and ladders. The use of a thermoplastic polyurethane, particularly the high Tg thermoplastic polyurethane as the impregnating resin provides a means of recycling and reusing the reinforced lumber, as well as shaping the composite in ways that would be impossible using conventional fiber-reinforced thermoset composites.</p> |
