Title:
複合材部品に長さ方向の湾曲を付与する引抜成形システム
Document Type and Number:
Japanese Patent JP7160548
Kind Code:
B2
Abstract:
A system and a method are provided for applying lengthwise curvature to composite parts. One embodiment is a method that includes fabricating a preform for a curved pultruded gap filler by continuously: heating fiber reinforced material (520) to a sticking point temperature for a constituent material within the fiber reinforced material, and feeding the fiber reinforced material through a die (550) that exhibits a curvature through which the fiber reinforced material travels while the fiber reinforced material is heated to the sticking point temperature, the die forming the fiber reinforced material into a preform for a gap filler (250). Fabricating the curved pultruded preform further includes varying path lengths of fibers within the preform as the preform passes through the die, and pulling the preform out of the die.
