Disclosed herein is a method for producing a part comprising at least one layer of fiber-reinforced composite material. Said method encompasses at least the following steps: a) the at least one layer of polymerizable fiber-reinforced composite material is arranged in a shape that has a base and a plurality of elevations; b) at least one mold is placed so as to be in contact with at least one elevation, said mold having a microwave-sensitive material at least on one contact surface towards the at least one elevation; c) the at least one elevation is polymerized by irradiating the at least one mold with microwaves. The mold used has a stable three-dimensional shape and has a contact surface for the part. At least the contact surface is made of microwave-sensitive material.

Method and mold for the production of parts from fiber-reinforced composite material by means of microwaves

A method for manufacturing a component comprising at least one layer having a fiber-reinforced composite material that absorbs microwaves is disclosed. The method comprises at least the following steps: a) arranging the at least one layer in a shape, b) treating a first surface section of the at least one layer with microwaves, wherein a temperature limiting mechanism of the at least one layer cooperate with at least one adjacent second surface section, at least part of the time. The method may be carried out in such that steps a) and b) are carried out for a plurality of components and that the components are further treated according to at least the following steps: c) positioning a plurality of components with respect to one another such that each second surface section forms at least one overlapping area at least partially, d) treating the at least one overlapping area with microwaves.
