The invention relates to a method for bonding a thermoplastic polymer to a thermosetting polymer component, the thermoplastic polymer having a melting temperature that exceeds the curing temperature of the thermosetting polymer. The method comprises the steps of providing a cured thermosetting polymer component comprising an implant of a thermoplastic polymer at least at the part of the thermosetting polymer component to be bonded, locating a thermoplastic polymer in contact with at least the part to be bonded, heating the assembly to the melting temperature of the thermoplastic polymer, whereby the thermoplastic polymer of the implant melts and fuses with the thermoplastic polymer, and cooling the assembly. The thermoplastic polymer has a melting temperature that exceeds the curing temperature of the thermosetting polymer, and the implant is designed such that heating above the maximum operating temperature of the thermosetting polymer at the interface of the implant with the thermosetting polymer component is avoided during the bonding step.

Method for bonding a thermoplastic polymer to a thermosetting polymer component

Method for the production of a laminate and bent product produced from such a laminate. The laminate is made up of at least two outer sheets of metal material with a layer of fibre-reinforced resin between them. During production the fibre layer is applied dry and the layer of resin material is applied around the fibre material only at a later stage. This can take place either by injection or by rendering fluid a layer of resin material that is applied adjoining the layer of fibre material in the laminate. In this way it is ensured that complete filling of the adjacent sheets of metal material with fibre-reinforced resin takes place even in bends.
