The invention relates to a method for manufacturing a panel (1, 21, 70, 71), for example an automobile panel such as a reclining backrest, loading floor, roof, door, engine hood, trunk lid and the like, which is characterized in that a prefabricated filling (5, 45) of foam plastic is placed in a mol
The invention relates to a method for manufacturing a panel (1, 21, 70, 71), for example an automobile panel such as a reclining backrest, loading floor, roof, door, engine hood, trunk lid and the like, which is characterized in that a prefabricated filling (5, 45) of foam plastic is placed in a mold cavity (59) between two layers (3, 4; 63, 64) of reinforced plastic, and that in a pressing process using heat and pressure said two layers of reinforced plastic are fused to each other while they enclose the foam plastic; and preferably the filling (5, 45) of foam plastic has at least one passage (10, 30, 31, 68), and that during the pressing process both the layers (3, 4; 63, 64) of reinforced plastic are fused to each other at the location of the passage (10, 30, 31, 68). And further the invention relates to a panel manufactured under application of the method.

The method of manufacturing an automotive panel such as a reclining backrest, loading floor, roof, door, engine hood, trunk lid and the like, which comprises the steps of prefabricating a filling of foamed plastic material defining contoured opposite side faces and having frusto-conical open areas within the peripheral confines thereof and extending between and to the opposite side faces of the filling, placing a first layer of fiber-reinforced thermoplastic material into conformity with an inner surface of the bottom half of a mold which has regions contoured similarly to one of the opposite side faces of the filling, placing one side surface of the filling onto a central region of the first layer, placing a central region of a second layer of fiber-reinforced thermoplastic material, compatible with the thermoplastic material of the first layer, onto the opposite side surface of the filling, closing a top half of the mold having regions contoured in accord with the opposite side surface of the filling onto the bottom half under pressure and while the layers are in plastic condition, one of the the top and bottom mold halves having frusto-conical projections reaching through the frusto-conical open areas, to fuse the first and second layers together around the peripheries of the central regions thereof and to each other through the open areas of the filling while intimately engaging the contoured regions of the mold halves against the layers and into contact with the filling.
