Abstract
The present invention is a method of making a polyurethane composite. The method includes forming a non-polar material into a predetermined shape and preparing its bonding through plasma treatment. Once the bonding surface has been prepared, the non-polar material is positioned in a mold and liquid precursors of polyurethane are poured into a cavity of the mold such that the liquid precursor of polyurethane is in contact with the bonding surface of the non-polar material. The liquid precursor of polyurethane is then cured to form a polyurethane material that is effectively joined to the bonding surface of the non-polar material to form the polyurethane composite material.
Claims8
A method of manufacturing a polyurethane composite material comprising the steps of:
- forming a non-polar material into a predetermined shape;
- preparing a bonding surface of said non-polar material by plasma treating said bonding surface;
- positioning said non-polar material in a mold;
- disposing liquid precursors of polyurethane into a cavity of said mold such that said liquid precursor of polyurethane is in contact with said bonding surface of said non-polar material;
- and
- curing said liquid precursor of polyurethane to form a polyurethane material;
- wherein said non-polar material and said polyurethane are effectively joined at said bonding surface of said non-polar material to form said polyurethane composite material.
