Disclosed are an automotive crash pad and a method for manufacturing the same. The automotive crash pad includes: a skin layer forming the outer surface of the crash pad including an airbag module; a fiber-based layer formed on the lower surface of the skin layer; a cushion layer formed on the lower surface of the fiber-based layer and including slab foam; and a core layer formed on the lower surface of the cushion layer, wherein a laminate of the skin layer and the fiber-based layer has a tensile strength in transverse direction (TD) of 5 to 50 kgf/3 cm and an elongation at break in transverse direction (TD) of 40 to 220%. The automobile crash pad provided by the present disclosure has excellent airbag deployment performance, and can omit the skin layer weakening treatment when forming the skin layer.

    本发明涉及一种汽车防撞垫及其制造方法。在一个实施例中,汽车防撞垫包括:表皮层,其形成包含安全气囊模块的防撞垫的外表面;纤维基层,其形成在表皮层的下表面上;缓冲层,其形成在纤维基层的下表面上且包含板状泡沫;以及芯层,其形成在缓冲层的下表面上,其中,表皮层和纤维基层的层压体具有5至50kgf/3cm的横向(TD)抗拉强度和40%至220%的横向(TD)断裂伸长率。本公开提供的汽车防撞垫具有优良的安全气囊展开性能,并且能够在形成表皮层时省去表皮层弱化处理。
