Polymer foams based on polyethersulfone (PESU) fulfil the legal specifications demanded by the aviation industry for aircraft interiors. Specifically the demands on fire characteristics, stability to media and mechanical properties constitute a great challenge here. According to the related art, suitable polymer foams are produced as semifinished products. Reprocessing to give shaped articles is uneconomic in terms of time and material exploitation, for example by virtue of large amounts of cutting waste. The problem is solved by the material which is suitable in principle can be processed to give particle foam mouldings. These mouldings can be produced without reprocessing in short cycle times and hence economically. Furthermore, this gives rise to new means of functional integration, for example by direct incorporation of inserts etc. in the foam, and with regard to freedom in terms of design.

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.
