    Abstract: The application of disc brakes on a large bus is more and more. The development of a brake pad with high performance and environmental protection for a bus has important social significance and economic value. The effects of the hardness of friction plate on brake noise was studied experimentally. The results show that the hardness of friction plat... Show More

    Abstract: A novel phosphorus-nitrogen flame retardant polyols (FRPE) was synthesized from condensation reaction with adipic acid (AA), ethylene glycol (MEG), diethylene glycol (DEG), maleic acid (MA), 9, 10-dihydro‐9‐oxa‐10‐phosphaphenanthrene‐ 10‐oxide (DOPO) and tris (2-hydroxyethyl) isocyanurate (THEIC) as raw materials. The structure of FRPE was characte... Show More
