The invention relates to a foam composite material which comprises a material in web form impregnated with a curable resin. The resin in the foam composite material is in the B-stage. The foam composite material further contains expanded thermoplastic particles which are essentially uniformly distributed in the resin and in the web material. The invention also relates to laminates prepared by use of the foam composite material and a method for the manufacture of such laminates.

A laminate comprising: a foam composite material and at least one further such a material or another sheet material in which each foam composite material includes (a) a material in the form of a thin web, (b) a curable resin in the C-stage, i.e. which has passed from an initial uncured A-stage, in which the resin is meltable, poorly cross-linked and soluble in solvents, via an intermediate B-stage to a cured C-stage, in which the resin is not meltable, completely cross-linked and insoluble, and (c) expanded thermoplastic microspheres and in which foam composite materials, the curable resin and the microspheres are uniformly distributed in the web material and whereby at least two materials are bonded to each other by a transition from B-stage to C-stage of the curable resin.
