Description

The present invention is applied to the technical field related to a sheet-like composite material structure used for the production of products such as front caps, rear caps, bags, etc., and in particular, allows the production thereof to be performed easily, conveniently and quickly. The present invention relates to a composite material structure that further strengthens the structure.

Usually, a sheet-like composite material used for manufacturing a product such as a conventional front cap, rear cap, bag, etc. is pre-applied with a layer of adhesive mainly on the upper surface of a single fabric base, Since it is configured by adhering a single layer of thermoplastic face material on the adhesive layer, the fabric has flexibility and waterproofness. However, the method of bonding the base material to the face material using an adhesive does not meet the weight reduction requirements for products such as athletic shoes because it is thick overall, and the manufacturing of the bonding becomes complicated. It takes time and effort and is not economical. In particular, the method of bonding using the adhesive is applied only when a planar face material is bonded to a planar substrate, and the substrate is used for a substrate having an uneven surface. Since the face material cannot be firmly bonded to the uneven surface of the base material by the adhesive method, peeling easily occurs.
