PULTRUDED BEAM REINFORCED WITH NATURAL FIBERS, PULTRUSION SYSTEM AND METHOD THEREFOR

A system for pultruding a beam, such as a pultruded beam of natural fibers, comprises a pulling mechanism continuously pulling on a preform of yarns including a thermoplastic matrix and fibers, the pulling mechanism being downstream of the system. A sequence is provided in the system and has a pre-heating module to pre-heat the preform. A first die has a tapering channel portion heated such that the preform reaches a desired low viscosity temperature for resin in the thermoplastic matrix to impregnate the fibers. A vacuum module has a vacuum cavity to remove air from the preform exiting the first die. A second die has a tapering channel portion heated such that the preform is at the desired low viscosity temperature for resin in the thermoplastic matrix to further impregnate the fibers. Acooling module to cool the beam before the beam reaches the pulling mechanism. A system for pultruding beams is also provided. 种用于拉挤梁的系统，所述梁例如为天然纤维的拉挤成型梁，包括拉动机构，其在包括热塑性基质和纤维的纱线的预制件上连续地拉动，拉动机构在系统的下游。顺序部件在系统中提供，并具有预热模块以预热预制件。第模
