## Abstract

A heterogeneous composite has a first layer which includes a fiber layer, a metal layer, a plastic layer or a combination thereof, a second layer which includes a fiber layer with a plastic layer, or a fiber layer with a non-woven cloth layer, and a base layer which is a thermoplastic layer. The first layer and the second layer are respectively mounted on the base layer by a glue layer, and the compressive strength value between the first layer and the second layer is less than 20%. The base layer enhances strength of the whole composite, and the heterogeneous composite provides a beautiful and competitive product.

## Claims
