Process for removing matrix resin from fibre reinforced composites

摘要

The defined region is subjected to microwave radiation. Microwaves (4) promote re-infiltration of resins into the defined region (3). These are repair resins, having the same composition as the original matrix resins. Microwaves are further employed for hardening of the re-infiltrated resin. Before re-infiltration, a further fiber structure is placed onto or joined to the fibers (12). This is infiltrated with the same resins, when the infiltration process takes place. The fiber structure is a region (3) of another fiber-reinforced plastic component (2), from which the matrix resins have been removed. Matrix resin vaporized by the process, is sucked away. The operation takes place in a protective gas atmosphere (8). The temperature of the fiber reinforced plastic component is monitored by non-contacting instrumentation.
