Verbundwerkstoff und Verfahren zu seiner Herstellung

摘要

A composite material consists essentially of a particle foam comprising expanded polypropylene (EPP), at least one fiber layer and at least one polymer introduced onto this layer. An intimate connection is secured in that the fiber layer is a mixed fiber layer comprising a fraction of fibers made from polypropylene (PP) which are welded to the EPP particles and with an additional fraction of reinforcing fibers which have a sufficient wetability for the hardening, curing or cross-linking polymer introduced onto the free surface of the fiber layer in the liquid phase. A method for producing these composite materials is also described.
