ABSTRACT:
A compression formed panel of a wood fiber board and a plastic resin means impregnated into the wood fiber board for maintaining the shape of said door core or panel after compression, and a method for making same requiring either a catalyst that causes the plastic resin to set at a temperature in excess of 100.degree. Celsius, or a catalyst that causes the plastic resin to set or polymerize at a temperature lower than 100.degree. Celsius.
The method includes a first step in which the wood fiber board is dipped into a plastic resin material mixture, containing the necessary catalyst for causing the plastic resin material to set, for a time sufficient for the wood fiber board to absorb a portion of the plastic resin material mixture; a second step in which the wood fiber board is placed in a compression means for compressing the compressible wood fiber board for a time sufficient to set the plastic resin material contained in the compressible wood fiber board, and a third step in which the resulting wood fiber panel is removed from the compression means. An optional step after the first step includes adding a fairing compound along the parts to be three dimensional.
