Abstract
método para reciclar sucata que contém uma ou mais fibras resistentes a calor e de 25 a 60% em peso, com base no peso total da sucata, de uma mistura de resinas termoendurecíveis de dois componentes pelo menos parcialmente não curadas a totalmente não curadas de (i) uma ou mais resinas termoendurecíveis e (ii) um endurecedor sólido, os métodos compreendendo triturar a sucata até um tamanho médio de 3 a 50 mm, misturar a sucata triturada, preferencialmente após pré-aquecimento da sucata, para fornecer uma carga de material fluido e, então, moldar por compressão a carga de material fluido para fazer um material compósito curado.
