Abstract: The invention relates to a composite material that consists of at least one first molded part and one second molded part. Said first molded part and sai d second molded part are rigidly linked with each other across at least a partial section with a surface .alpha. of the first molded part and a surfac e .beta. of the second molded part by means of a welded zone. At least the fir st molded part consists by at least 50 % by weight, based on the first molded part, of a molding compound that contains: A) 5 to 99 % by weight of a polyester, B) 1 to 95 % by weight of a fibrous filler that is treated with a n aminosilane compound and an epoxypolymer, C) 0 to 30 % by weight of a rubber - elastic polymer, D) 0 to 40 % by weight of further additives, the weight percentages of components A) to D) adding up 100 %. The invention also relat es to laminates that consist of said composites and to structures and recycled products obtained thereof and to the use of all these products, especially i n the manufacture of automobiles.

Abstract: In a composite with at least two moulded parts bonded together at a weld zone, at least 50 wt% of at least one of these parts consists of a fibre-reinforced polyester moulding material in which the fibrous filler is pretreated with an aminosilane compound and an epoxy polymer. A composite with at least two moulded parts (1, 2) rigidly bonded together at a weld zone covering at least part of their surfaces ( alpha and beta respectively), in which at least 50 wt% of at least part 1 consists of a moulding material containing: (A) 5-99 wt% polyester; (B) 1-95 wt% fibrous filler pretreated with an aminosilane compound and an epoxy polymer; (C) 0-30 wt% rubber-elastic polymer; and (D) 0-40 wt% other additives. Independent claims are also included for: (a) a process for the production of these composites by welding at least part of surfaces alpha and beta together to form a weld zone; (b) composites obtained by this process; (c) recycling moulded parts or moulding materials from these composites or the composites themselves; (d) recycled material obtained from the parts, moulding materials or composites; and (e) formed products or laminates containing these composites and/or recycled materials.
