SEMI-FINISHED PRODUCT MANUFACTURED FROM PREPREG, THREE-DIMENSIONAL PREFORMED BODY AND OVERMOULDED PART

The present invention provides a semi-product made of a prepreg, a three-dimensional preform and an overmolded part. More particularly, the present invention provides a semi-product made of a prepreg, including at least a first prepreg layer and a second prepreg layer, characterized in that a metal layer is laid between the first prepreg layer and the second prepreg layer. Since the metal layer is added between the prepreg layers, the three-dimensional preform made of the semi-product can be supported by the metal layer during a reheating process prior to overmolding, thereby well maintaining its three-dimensional shape without collapsing. In addition, since the added metal layer is retained in a final overmolded product, it can enhance mechanical strength of the product and serve as a supplementary reinforcement.
