Solid composite boards having a compact core of adhesive binder and 85{14 98 percent by volume of porous, nonabsorbing granulates selected from the group consisting of cork bark, and vermiculite

Abstract

Abstract A solid board, such as a door plate, comprising a solid core having a first and second core face and a frame surrounding said core adhesively connected thereto and having a first and second frame face flush with said first and second core face respectively. The first and second surface sheets are uniformly adhesively secured to the first core and frame face and to the second core and frame face respectively; the core consists of a compact core mass-produced from porous nonabsorbing granulates, which have been brought mutually to adhere to each other by adhesive means. There are reinforcement means embedded in the core mass which consist of a number of strips made of fibrous material each having a width equal to the frame thickness and extending between the two surface sheets.
