Abstract
A foamed phenolic molding composed of a core made of a kraft paper honey comb structure consisting of plate and corrugate members impregnated with a phenolic resin; and expandable phenolic composites laminated to said core, wherein the expandable phenolic composites are made of a matted fiber material formed in the shape of a plate to which phenolic resin is bonded to at least one thereof. The expandable phenolic composites and core are molded such that the expandable phenolic material fills the cells of the kraft paper honey comb structure. The molding has excellent thermal insulation and sound insulating properties as well as high strength as compared to conventional cores without sacrificing to the lightweight characteristics and workability of the quadratic surfaces.
