Abstract:
1. A process for producing a foam composite having a skin with an even thickness and a core comprising foamed bodies with homogeneous and fine bubbles and spherical plastic reinforcing members with an even thickness covering each of the foamed bodies, comprising: charging a mold with one of plastic powders and plastic minute particles, and polyolefin pellets that are larger than the one of the plastic powders and the plastic minute particles, wherein the polyolefin pellets are covered in the whole surface with plastic and are cross-linkable and foamable; and heating the mold from the outside of the mold; rotating the mold at within a range from 1 to 20 rpm, so that a plastic skin is formed and the pellets adhere to the skin; and further heating the mold, thereby permitting the polyolefin cross-links and the pellets to expand by the decomposition of a foaming agent, wherein and wherein the polyolefin pellets are formed by
