Abstract
Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A PRODUçãO DE MATERIAIS COMPOSTOS CONTìNUOS"<D>. A presente invenção refere-se a um processo e também a um dispositivo para a produção de materiais compostos contínuos a partir de fibras de reforço unidirecionais e de materiais sintéticos termoplásticos, sendo que o feixe, móvel em direção longitudinal, de fibras de reforço contínuas e paralelas é preaquecido e é impregnado com massa fundida termoplástica abastecida continuamente, e depois disso o material composto contínuo assim formado é esfriado. Para aperfeiçoar o processo de impregnação, a invenção porpõe que a massa fundida termoplástica forme um trecho longitudinal de impregnação, no qual, para se reduzir a viscosidade da massa fundida, introduz-se continuamente energia mecânica, e que o feixe de fibras preaquecido seja puxado continuamente através da zona de viscosidade reduzida da massa fundida.
