    摘要: The present invention relates to a method for producing a molded body from a blowing-agent containing foam material, which comprises at least one fiber (F), said at least one fiber (F) being partly introduced into the blowing-agent containing foam material. The two ends of the respective fiber (F) which are not surrounded by the foam material thus protrude on one side of the corresponding molded body. The invention further relates to a molded body as such. The invention also relates to a panel which comprises at least one such molded body produced according to the method of the invention, and at least one additional layer (S1). The invention further relates to the production of the panels according to the invention and to the use thereof, for example as rotor blades in wind turbines.
