Abstract
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%.

An automotive crash pad comprising:
- a skin layer forming an outer surface of the crash pad including an airbag module;
- a fiber-based layer formed on a lower surface of the skin layer;
- a cushion layer formed on a lower surface of the fiber-based layer and comprising slab foam;
- and
- a core layer formed on a lower surface of the cushion layer,
- wherein a laminate of the skin layer and the fiber-based layer has a tensile strength in a transverse direction (TD) of 5 to 50 kgf/3 cm and an elongation at break in a transverse direction (TD) of 40 to 220%.
A method for manufacturing an automotive crash pad, the automotive crash pad including:
- a skin layer forming an outer surface of the crash pad including an airbag module;
- a fiber-based layer formed on a lower surface of the skin layer;
- a cushion layer formed on a lower surface of the fiber-based layer and including slab foam;
- and a core layer formed on a lower surface of the cushion layer, the method comprising:
- preparing an intermediate by laminating the cushion layer and the core layer together;
- and
- laminating the fiber-based layer and the skin layer onto the intermediate,
- 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%.
