Abstract

A fiber composite structural component such as a fitting, bracket, mounting or the like is produced by applying fiber material such as fiber threads or fiber yarns in an automatic circular weaving operation to a core that has at least two sections, to form a fiber material body (6). One core section is removed from the fiber material body when the weaving is completed. The body is then deformed in a mold that has the contour of the finished structural component with at least one mold core section still in the fiber material body. The deformed configuration of the structural component is then impregnated in an RTM device with a resin and hardener followed by curing. Reinforcements may be inserted or secured to the fiber material body prior to the impregnated and curing step.
