To provide a novel vehicle interior material in which deformation of a base material and peeling of a molded portion starting from a rib are suppressed.SOLUTION: A vehicle interior material 1 includes a molded base material 2 including air Ar and a molded portion 3 of resin R1 joined to a part of one surface of the base material 2. The molded portion 3 has a main body part 30 and a returning rib 40 that extends from the main body part 30 along one surface (for example, a rear face 2b) of the base material 2 and returns to the main body part 30 while changing a direction to a curved shape. A method of manufacturing the interior material 1 includes a base material forming step ST1 of forming the base material 2 having a required shape including the air Ar, a transfer step ST2 of transferring the base material 2 to an injection molding die 310 having a cavity CA0 forming the molded portion 3, and an injection step ST 3 of injecting the resin R1 into the cavity CA0 of the injection molding die 310 on which the base material 2 is arranged.SELECTED DRAWING: Figure 3
【課題】基材の変形、及び、リブを起点とした成形部の剥がれが抑制された新規の車両用内装材を提供する。【解決手段】車両用内装材1は、空気Arを含む成形された基材2と、該基材2の一面の一部に接合された樹脂R1の成形部3と、を備える。成形部3は、本体部30と、基材2の一面(例えば裏面2b)に沿って本体部30から延びて曲線状に向きを変えて本体部30に戻る回帰リブ40と、を有する。内装材1の製造方法は、空気Arを含む所要形状の基材2を形成する基材形成工程ST1と、前記成形部3を形成するキャビティCA0を有する射出成形型310に基材2を移す移送工程ST2と、基材2が配置された射出成形型310のキャビティCA0に樹脂R1を射出する射出工程ST3と、を含む。【選択図】図3
