Comparison Experimental Study on Apparent Porosity of Brake Linings for Car Based on Water Granulating Technology

In this paper, the contrast test has been done on the brake linings that have been made by water granulating technology. As a result, by contrast with the brake linings that have been done at the same material and producing technology, it was preliminary demonstrated that the apparent porosity of the brake linings that have been made by the granulating technology could be enhanced greatly, so on the hot-pressing process, products exhausting has been easy, the die cavity volume could be decreased, the hot-pressing time could been shorten, the production efficiency could be enhanced, the natural frequency of the braking lining could be reduced, the possibility of the braking noise could be decreased.
