Title (EN) INTEGRATED MOLDED BODY AND METHOD FOR PRODUCING SAME
(FR) CORPS MOULÉ INTÉGRÉ ET SA MÉTHODE DE PRODUCTION
(JA) 一体化成形体およびその製造方法
Abstract:
(EN) The purpose of the invention is to solve the problem of decreased strength/rigidity in the weld line of an injection molded body, and enable free design, such as the injection molding of thin-walled products or products having complicated shapes. Provided is an integrated molded body in which a reinforcing substrate (a) having a discontinuous fiber (a1) and a resin (a2) is integrated with an injection molded body (b) having a discontinuous fiber (b1) and a resin (b2), wherein the difference in the orientation angle of the discontinuous fiber (a1) in each of 10 equally divided regions of the reinforcing substrate (a) along the longitudinal direction is 10° or less, and the reinforcing substrate (a) is integrated with the injection molded body (b) so as to cover a portion or all of the weld line of the injection molded body (b).
(FR) L'objectif de l'invention est de résoudre le problème de résistance/rigidité réduite dans la ligne de soudure d'un corps moulé par injection, et permet une conception libre, telle que le moulage par injection de produits à paroi mince ou de produits ayant des formes compliquées. L'invention concerne un corps moulé intégré dans lequel un substrat de renforcement (a) ayant une fibre discontinue (a1) et une résine (a2) est intégré à un corps moulé par injection (b) ayant une fibre discontinue (b1) et une résine (b2), la différence dans l'angle d'orientation de la fibre discontinue (a1) dans chacune de 10 régions également divisées du substrat de renforcement (a) le long de la direction longitudinale est de 10° ou moins, et le substrat de renforcement (a) est intégré au corps moulé par injection (b) de manière à recouvrir une partie ou la totalité de la ligne de soudure du corps moulé par injection (b).
(JA) 射出成形体の課題であるウェルドラインでの強度・剛性低下を解決し、射出成形体の薄肉成形あるいは複雑形状成形など自由な設計を可能とすることを目的とし、不連続繊維(a1)と樹脂(a2)とを有する補強基材(a)と、不連続繊維(b1)と樹脂(b2)とを有する射出成形体(b)とが一体化した一体化成形体であり、補強基材(a)の長軸方向を10等分に区分した領域の各々における不連続繊維(a1)の配向角度の差が10°以内であり、補強基材(a)が射出成形体(b)のウェルドラインの一部又は全部を覆って射出成形体(b)と一体化している、一体化成形体とする。
