Abstract: The invention relates to fiber-reinforced composites acting as an actuator, as a sensor and/or as a generator and to a manufacturing process. It is the object of the invention to provide such fiber-reinforced composites which can be manufactured simply and reliably and which are securely fastened and exactly positioned as elements acting as actuators, generators and/or sensors. In a fiber-reinforced composite in accordance with the invention, at least one piezoelectric element is fixed and positioned by fibers or yarn within a fiber structure or by means of fibers or yarn to a fiber structure. Flexible, electrically conductive connections which can be contacted from outside the fiber-reinforced composite are led at and/or within the fiber structure to electric connector contacts of the at least one piezoelectric element. One or more piezoelectric elements, electrically conductive connections and the fiber structure are embedded in a matrix material.
