PROBLEM TO BE SOLVED: To provide a vehicular interior material and a molding method thereof capable of securing sufficient adhesive areas on sliced surfaces and increasing adhesive strength, even when using a foam sliced sheet as a foam sheet which is a trim base material.SOLUTION: In a roof trim 1 formed in such a manner that a trim base material 2 and mounting materials 3 and 4 on both sides of the trim base material 2 are integrally bonded together, a foam sliced sheet formed after a hard foam resin material is sliced to a required thickness is used as a foam sheet 5 constituting the trim base material 2. Preliminary thermoforming is performed on ribs 5a of foam cells sliced and exposed to sliced surfaces, and the ribs 5a fall uniformly and deformed. Therefore, adhesive areas relative to stiffening sheets 6 and 7 are expanded and required sufficient strength can be secured.SELECTED DRAWING: Figure 1

    【課題】トリム基材の発泡シートとして発泡スライスシートを用いても、そのスライス加工面に十分な接着面積を確保できて接着強度を高めることができる車両用内装材およびその成形方法の提供を図る。【解決手段】トリム基材2とその両側の表装材3,4とが一体に接合したルーフトリム1は、トリム基材2を構成する発泡シート5として硬質の発泡樹脂材を所要の厚さにスライス加工した発泡スライスシートが用いられ、そのスライス加工面に露出したスライスされた発泡セルのリブ5aを予備熱成形して一様に倒れ変形させている。そのため、補剛シート6,7に対する接着面積が拡大されて要求される接着強度を十分に確保することができる。【選択図】図1
