PULTRUSION MOLDING SYSTEM THAT APPLY LENGTHWISE CURVATURE TO COMPOSITE PART

PROBLEM TO BE SOLVED: To provide a system and method for applying lengthwise curvature to a composite part.SOLUTION: There is provided a method including fabricating a preform (250) for a curved pultrusion molding gap filler by continuously: heating a fiber reinforced material (520) to a sticking point temperature of a constituent material in the fiber reinforced material; and feeding the fiber reinforced material through a die (550) that exhibits a curvature through which the fiber reinforced material passes while the fiber reinforced material is heated to the sticking point temperature to form the fiber reinforced material into a preform. Fabricating the curved pultrusion molding preform further includes varying path lengths of fibers in the preform as the preform passes through the die, and pulling the preform out of the die.SELECTED DRAWING: Figure 5A 【課題】複合材部品に長さ方向の湾曲を付与するためのシステム及び方法を提供する。【解決手段】方法であり、当該方法では、繊維強化材料（５２０）を、前記繊維強化材料内の構成材料の粘着点温度まで加熱し、前記繊維強化材料が前記粘着点温度まで加熱された状態で、前記繊維強化材料が通過する湾曲を有するダイ（５５０）に前記繊維強化材料を供給して、前記繊維強化材料をプリフォームに成形する、ことを連続的に行って、湾曲引抜成形ギャップフィラーのプリフォーム（２５０）を作製する。前記湾曲引抜成形プリフォームの作製は、さらに、前記プリフォームが前記ダイを通過する際、前記プリフォーム内の繊維の経路長を変化させ、前記ダイから前記プリフォームを引き抜く、ことを含む。【選択図】図５Ａ
