Fibre-composite laminar element

摘要

The invention relates to a fibre-composite laminar element provided with transverse bores for bolts, in which two covering layers (1, 2) of fibre strands in unidirectional fibre orientation over the length of the element are bonded by a shear-transferring intermediate layer (3). In order in the case of this laminar element to permit force introduction without reducing the strength of the covering layers (1, 2), according to the invention the transverse bores (5) are located only in (uncovered) areas (3.1) of the intermediate layer (3), made up of a fibrous tissue or fibrewoven fabric, which protrude on the two longitudinal edges of the covering layers (1, 2). In addition, the covering layers (1, 2) are clamped in between two flexurally rigid plates (7, 8) under screwing-on pressure effected by the bolts (6), the screwing-on pressure acting on at least one (7) of these plates by means of an interposed thrustpiece (9) supported in the centre of the plate. <IMAGE>
