Title (EN) HYBRID FIBER BASED MOLDING THERMOPLASTIC ARTICLE AND PROCESS OF FORMING SAME
(FR) ARTICLE THERMOPLASTIQUE DE MOULAGE À BASE DE FIBRES HYBRIDES ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A process is provided for thermal molding an article with at least one layer of thermoplastic fibers that are non-woven and uni-directionally oriented in combination with at least one layer of reinforcing fibers. The reinforcing fibers including glass, carbon, nature based, and combinations thereof; alone or mixed with chopped thermoplastic fibers. Upon subjecting the layers to sufficient heat to thermally bond in the presence of non-oriented filler fibers, thermoplastic fiber fusion encapsulates the filler fibers. The filler fibers impart physical properties to the resulting article and the residual unidirectional orientation of the thermoplastic melt imparts physical properties in the fiber direction to the article. By combining layers with varying orientations of uni-directional fibers relative to one another, the physical properties of the resulting article may be controlled and extended relative to conventional thermoplastic moldings. The uni-directional fibers may have discontinuities along the length of individual fibers.
(FR) L'invention concerne un procédé de moulage thermique d'un article présentant au moins une couche de fibres thermoplastiques qui sont non tissées et orientées de manière unidirectionnelle en combinaison avec au moins une couche de fibres de renforcement. Les fibres de renforcement comprennent des fibres de verre, de carbone, naturelles, et des combinaisons de celles-ci, seules ou en mélange avec des fibres thermoplastiques coupées. Lorsque les couches sont soumises à une chaleur suffisante pour se lier thermiquement en présence de fibres de charge non orientées, une fusion de fibres thermoplastiques encapsule les fibres de charge. Les fibres de charge confèrent à l'article résultant des propriétés physiques et l'orientation unidirectionnelle résiduelle de la matière fondue thermoplastique confère à l'article des propriétés physiques dans la direction des fibres. En combinant des couches dont les fibres unidirectionnelles présentent des orientations différentes les unes par rapport aux autres, les propriétés physiques de l'article résultant peuvent être contrôlées et étendues par rapport aux moulages thermoplastiques classiques. Les fibres unidirectionnelles peuvent présenter des discontinuités le long de la longueur des fibres individuelles.
