MANUFACTURE OF FLAT OR SHELL-SHAPED CURVED STRUCTURE PART

The construction elements concerned are made from fibre-reinforced plastics, are of various dimensions and are provided with stringers, ribs or frames as reinforcing profiles. First of all, original reinforcing profiles (7) are arranged on the contour (3) of a mould cavity (2) as a means of moulding. Then a fibre-reinforced elastomer or plastic is applied to the given construction element inner contour of a model (5), followed by curing of the mat (14). The mat (14) is then taken out of the mould and the model (5) is removed from the mould cavity (2). Prefabricated, not fully cured reinforcing profiles (7') of fibre-reinforced plastics, such as stringers, ribs or frames, are then introduced into the mat (14) which is provided with clearances (15). A flat, uncured planking structure (17) of fibre-reinforced plastics is laid on the mat (14) provided with the reinforcing profiles (7'). This is followed by shaping of the planking structure (17) over the mat (14) and laying of the mould cavity (2) onto the shaped planking structure (17), the mat (14) being sealed off (19) vacuum-tightly from the mould cavity (2) at the ends (18) and subsequently bonded together in an oven or autoclave at a temperature of up to a maximum of 400 DEG C and under a pressure of up to a maximum of 15 bar and completed in a single operation.
