    Abstract: Synthetic resin composite profile, in particular wing spar for aircraft construction, comprising at least two flanges (1) provided with adhesive bonding flanges and at least one web (2) interconnecting the flanges (1) and inserted into the adhesive bonded flanges, the flanges (1) being constructed of resin impregnated rovings and the web (2) of resin impregnated woven or non-woven fabrics and the flanges (1) and the web (2) being adhesively interconnected. The flanges (1) are pultruded, the web (2) being inserted into the adhesive bonding flanges of both flanges (1) and fixed therein by means of a thixotropic adhesive (4). This manner of construction ensures that the full flange adhesive bonding width is retained even if the component height should change.
