摘要： The present invention relates to a novel method which is suitable, for example, for producing composite materials with cores made from hard foams. It is the advantage of the invention here that both the foam material and the plastic of the top layer can be selected freely. In particular, the present method can also be used to process top layers, the processing temperature of which differs clearly from those of the core material. Furthermore, the present invention relates to a method, by way of which integral foam structures can be compressed partially in a second embodiment. It is possible by way of a third embodiment to produce a hollow body with particularly high-quality joints from at least two workpieces of a foam by welding. This can take place here with or without top layers. Moreover, it is particularly satisfactorily possible by way of the present method to process foam materials by means of a vacuum moulding process.

摘要： The present invention relates to a novel method for producing novel fibre-reinforced profile materials, which are filled with a PMI foam core. In particular, the present invention relates to a novel pultrusion method, for short pul-core method, by means of which the fibre-reinforced profile material is produced and at the same time filled with the PMI foam core in one method step. In this case, very good bonding of the PMI foam core to the fibre-reinforced profile material is ensured in the one and the same method step.

摘要： The use of a solid, foamable plastic, for example poly(meth)acrylimide (PMI), polyvinyl chloride (PVC), polyurethane (PU) or poly(meth)acrylate (PMMA), permits the production of a plastics foam composite moulding which is in essence homogeneous and which, in the course of the foaming process at about 200 degrees Celsius, forms a stable mechanical bond with an outer layer or a plurality of outer layers or with a plurality of identical or different outer layers.
