Even in the heat resistance test, which was repeated for 2 hours, the nonwoven fabric 6 showed good results with no lifting or shrinkage at all.
しかして本発明は、囲体と不織布を重ねて加熱成形づる
にあたり、不織布の両面に低融点樹脂シートを配置する
ようにしたので、良好な接着成形体が得られる。According to the present invention, when the surrounding body and the nonwoven fabric are stacked and heat-formed, a low melting point resin sheet is placed on both sides of the nonwoven fabric, so that a good adhesive molded product can be obtained.

を特徴とづる車両用内装板の製）も方法。A fibrous carcass and a thermoplastic synthetic resin non-woven fabric are layered together and pressed together using a mold consisting of an upper mold and a lower mold to produce an interior board in which the non-woven fabric is adhered to the fibrous compression-molded body. The carcass is a bulky fibrous mat-like carcass containing a thermosetting synthetic resin, and the nonwoven fabric has a melting point of 240 to 260°C and a quantitative basis weight of 150 to 4009/lri. A thermoplastic synthetic resin non-woven fabric is used, and the low-melting point resin sheet overlaid on both sides of the non-woven fabric has a melting point of about 110 to 200°C and a quantitative basis weight of 10 to 50.
Prepare two sheets of thermoplastic synthetic resin of g/rd, and place them one on top of the other in this order: low melting point resin sheet, nonwoven fabric, low melting point resin sheet, and carcass, and place these sheets in a mold consisting of an upper mold and a lower mold. , the upper molding temperature was about 120 to 220°C, the lower molding temperature was about 200 to 250°C, and the upper molding temperature was lower than the lower molding temperature, and the pressure ICl was 9 to 25.
/c4. This method is also used to manufacture vehicle interior panels, which are characterized by tightening in a JT tightening time of about 30 seconds to 4 minutes.
