The invention relates to a crash pad for a vehicle and a manufacturing method of the crash pad. In one embodiment, the crash pad for the vehicle includes a skin layer configured to form an outer surface of the crash pad including an airbag module; a core layer formed on the lower surface of the skin layer; and a foam layer formed between the core layer and the skin layer, wherein the skin layer has a tensile strength of 15-120 kgf/cm2 and an elongation at break of 50-700% as measured in accordance with JIS K6301 standard, and the skin layer has an adhesive strength of 0.25 kgf/cm or more as measured in accordance with ISO 813 standard. According to the crash pad for the vehicle, the surface nicking treatment is omitted, when external impact is applied, a safety air bag can still be rapidlyunfolded, the tearing shape is good, the bonding strength between the foam layer and the surface layer of the crash pad is excellent, and the light weight and the mechanical property are excellent. Moreover, the process is simplified and the cost is reduced due to the omission of skin nicking treatment, so that the economic efficiency is excellent.

    本公开涉及一种车用防撞垫及其制造方法。在一个实施方式中,车用防撞垫包括:表皮层,其被配置为形成包含安全气囊模块的防撞垫的外表面;芯层,其形成在表皮层的下表面上;泡沫层,其形成在芯层和表皮层之间,其中,根据JIS K6301标准测得,表皮层的拉伸强度为15~120kgf/cm2,断裂伸长率为50~700%,并且根据ISO 813标准测得,表皮层的粘合强度为0.25kgf/cm以上。本公开的车用防撞垫省略了表皮刻痕处理,当施加外部冲击时,安全气囊仍可以快速展开,撕裂形状是良好的,防撞垫的泡沫层和表皮层之间的粘合强度是优异的,轻质和机械性能是优异的,并且由于省略表皮刻痕处理而简化了工艺并降低了成本,经济效率是优异的。
