CARRIER MATERIAL FOR HOLDING POLISHING WORKPIECE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a carrier material for holding a polishing workpiece of high productivity and a method of manufacturing the same, capable of dispens ing with a PP sheet process using an organic solvent in comparison with a conventional carrier material using a thermosetting resin. SOLUTION: This carrier material is composed of a layered product of plural sheets of fiber reinforced resin sheets 5, a thermoplastic resin is used as a matrix resin of the fiber reinforced resin sheets, the carrier material in which the sheet-shaped based material of the reinforcement fiber is buried in the matrix resin is molded, and a carrier 1 having teeth 2 and holding holes 3 is cut out from the carrier material. The carrier material is manufactured by inserting the thermoplastic resin film or powder among plural sheets of base materials of the reinforcement fiber, and integrally heating and pressing the same.
