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: ##STR1## 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.

A invenção atual relaciona-se à madeira que é reforçada com um composto thermoplastic fiber-reinforced que contenha um plurality das fibras contínuas substancialmente paralelas impregnadas com o polímero thermoplastic que tem as seguintes unidades estruturais: ## do ## STR1 onde Z é S ou O, e Z ' é S, O, o N-n-alkyl ou o NH a invenção são úteis em uma variedade das aplicações including estruturas colagem-laminadas, a madeira serrada laminada do folheado, i-beams reforçados, a madeira serrada paralela da costa, a placa de partícula reforçada, e as escadas. O uso de um poliuretano thermoplastic, particularmente o poliuretano thermoplastic elevado do Tg como a resina impregnando fornece meios de recycling e de reúso a madeira serrada reforçada, as.well.as dar forma ao composto nas maneiras que seriam compostos fiber-reinforced convencionais se usando impossíveis do thermoset.
