Title:
MOLDING BASE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/100739
Kind Code:
A1
Abstract:
The present invention relates to a molding base material (10) with which it is possible to prepare a vehicle exterior material such as an underbody shielding material. As a result of continued investigations, the applicant of the present application found that the objective of the present invention could be achieved by means of a "molding base material including a fiber base material layer (1) and a cover layer (3), wherein the fiber base material layer and the cover layer are integrally bonded to one another by means of a polypropylene-based resin layer (5) present at the interface between the fiber base material layer and the cover layer", and wherein the fiber base material layer contains sheath-core type composite fibers of which the core portion is a polyester-based resin and the sheath portion is a polypropylene-based resin. That is, it was found, for example, that a vehicle exterior material prepared using a molding base material satisfying this composition does not readily suffer from inter-layer peeling under high-temperature conditions, and has excellent heat resistance.
