Problems solved by technology

However, the current research on friction modifiers is mainly focused on the selection of one or two materials. This research method leads to the research results of the literature reported so far. It can be seen that most of the conclusions are that a certain material is Which aspect of a certain property has a beneficial effect, while its detrimental effect on other aspects is less reported
The problem it brings is that the comprehensive performance of the existing friction materials is not very ideal, and it is difficult to meet the increasing demand for safety, efficiency and environmental protection

Description

technical field [0001] The invention relates to the field of friction materials, in particular to a friction material for automobile braking. Background technique [0002] Friction material is a key safety part in the clutch assembly and brake of vehicles and machinery. During the transmission and braking process, the following technical requirements should be mainly met: 1. Appropriate and stable friction coefficient. 2. Good wear resistance. 3. Has good mechanical strength and physical properties. 4. Low braking noise. 5. The dual surface wears less. [0003] The friction material is a polymer ternary composite material, which is a physical and chemical complex. It is composed of polymer binder (resin and rubber), reinforcing fiber and friction performance regulator and other compounding ingredients, and is a product made through a series of production and processing. The friction material is characterized by good friction coefficient and wear resistance, as well as c...
