PULTRUSION SYSTEM APPLYING LENGTHWISE CURVATURE TO COMPOSITE PARTS

The invention provides a pultrusion system applying lengthwise curvature to composite parts. A system and a method are provided for applying lengthwise curvature to composite parts. One embodiment isa method that includes fabricating a preform for a curved pultruded gap filler by continuously: heating fiber reinforced material to a sticking point temperature for a constituent material within thefiber reinforced material, and feeding the fiber reinforced material through a die that exhibits a curvature through which the fiber reinforced material travels while the fiber reinforced material isheated to the sticking point temperature, the die forming the fiber reinforced material into a preform for a gap filler. Fabricating the curved pultruded preform further includes varying path lengthsof fibers within the preform as the preform passes through the die, and pulling the preform out of the die. 本发明的题目是施加纵向曲率至复合材料部件的拉挤成型系统。提供了用于施加纵向曲率至复合材料部件的系统和方法。种实施方式是方法，其包括通过连续地进行下述步骤制造弯曲的拉挤成型间隙填料的预成型件：加热纤维增强材料至纤维增强材料内的构成材料的粘着点
