Abstract

A production method for producing molded articles from fiber composites, superparamagnetic particles are selected which become coupled to an external alternating magnetic field. These superparamagnetic particles are added to a resin portion of a strip-shaped starting material further comprising reinforcing fibers. The strip-shaped starting material is then continuously advanced, and, while being advanced, heated by coupling-in an external alternating magnetic field to which the superparamagnetic particles in the resin portion become coupled. Next, the heated starting material is continuously molded into a molded article; and the resin portion in the molded particle is cured.
