Process for the production of a laminated composite product and a composite product made by the lamination process

Abstract

The invention is directed to a process for the making of a product out of laminated composite material. The process in general comprises preforming at least one layer of material such that it corresponds to a surface of a part; applying layers of fibers to the preformed layer of material; and bonding the fibers by a resin to form a laminated composite material.

1 . A part ( 11 ) made by a process comprising the following steps:
 a) preforming at least one layer ( 1 ) of material in a first auxiliary tool ( 3 ) such that it corresponds at least partially to a surface ( 2 ) of the part ( 11 );   b) applying layers ( 6 ) of fibers to the preformed layer of material ( 1 ); and   c) bonding the fibers by a resin in a production tool ( 7 ) to form a composite material,   wherein the composite material ( 6 ) is bonded to at least one preformed layer of material ( 1 ).   
     
     
         2 . The product according to  claim 1 , wherein the preformed layer of material comprises a thermoformable material preformed by at least one of heating, deep drawing, extruding, injection molding, and blowmolding. 
     
     
         3 . The product according to  claim 1  wherein the preformed layer ( 1 ) is arranged at an outside surface of the product. 
     
     
         4 . The product according to  claim 3 , wherein the pre-formed layer of material ( 1 ) comprises at least one material out of the group of Polyethylene Terephthalate (PET), Polycarbonate (PC), Polyamide (PA), Polymethylmethacrylat (PMMA), Polybutylenterephthalat (PBT, PBTP). Polyurethan (PUR), AcrylicM Films, fibrous material. 
     
     
         5 . The product according to  claim 4 , wherein an additional layer is arranged between the composite material ( 6 ) and the preformed layer of material ( 1 ). 
     
     
         6 . The product according to  claim 5 , wherein the additional layer comprises at least one of a layer of paint, a layer of hot-melt glue and a layer comprising visible information.
