description The invention provides a copper-based friction plate for a heavy-duty truck clutch and a manufacturing method. The copper-based friction plate is mainly formed by sintering a pressed friction layer powder sheet and a copper-plated core board in a compounded manner. The friction layer powder sheet is composed of, by weight percent, 40% of Cu, 3% of Pb, 5% of C, 12% of zirconium silicate, 15% of Fe, 2% of calcium oxide and 2% of aluminum oxide. The manufacturing method includes the steps that firstly, materials of the friction layer powder sheet are prepared; secondly, the materials of the friction layer powder sheet are mixed; thirdly, the friction layer powder sheet is pressed, the mixed materials mixed through the second working procedure are placed in a mold and pressed by a press machine to form the friction layer powder sheet; fourthly, the core board is plated with copper, wherein the core board is electroplated with copper through an electroplating method; fifthly, compound-sintering is performed, the friction layer powder sheet pressed through the third working procedure and the copper-plated core board manufactured through the fourth working procedure are compounded together and then placed in a bell jar furnace so as to be pressurized and sintered; and sixthly, coining is performed, wherein the copper-based friction plate compound-sintered through the fifth working procedure is pressed through the press machine.
