Abstract
The production method of friction lining for carbon-fibre brake includes the following steps: using carbon fibre as main body reinforcing material, cutting carbon fibre, mixing the cut carbon fibre with phenolic resin ethanol solution, adding powdered filler, fully mixing them and combining them with metal lining, and forming by hot-moulding so as to obtain the invented product. The barbon fibre possesses stable mechanical strength which does not decayed within 2000 deg.C, and its firction coefficient can be raised with raised temp., so that its brake effect is not reduced, suitable for high-speed running, and its friction coefficient is about 0.45.
Description
The invention belongs to automobile and vehicle parts, relate to a kind of invention brake bush.
The automotive brake friction facing is one of strength member of automobile industry at present, along with developing of automobile industry, more and more higher to its technical feature requirement, primary contains the brake lining development of incompatibility motor vehicle already of asbestos, is replaced with semimetallic brake lining.Development carbon-to-carbon fibre vehicle brake lining and small serial production all are higher than semi-metallic brake friction linings in its braking ability and work-ing life now.But be mainly used in high-grade car, so production cost is very high.The production of China's automobile brake disc liner is also very backward, and cargo truck is not also banned the brake facing of asbestos products so far, and the semi-metal of production comprises the semi-metallic brake friction linings that introducing equipment is produced, and technical indicator does not also reach and is the supporting requirement of auto-producing.
It is simple to the purpose of this invention is to provide a kind of manufacturing process, and cost is low, and technical parameter and performance all can reach the carbon fiber brake facing of technical requirements.
Technical scheme of the present invention is carbon fiber to be carried out with fleut and resol ethanolic soln that banburying mixes after treatment after drying treatment and after heat treatment promptly make carbon fibre friction facing for brake device through hot compression molding with the metal liner.
Technology of the present invention is:
It is that carbon fiber is standby through cutting off that carbon fiber is handled, resol and ethanol are by weight dissolving back and carbon fiber through cutting off at 1: 1 in the banburying in-tank mixing, add behind thorough mixing through mixed fleut, fleut is made up of barium sulfate, chromite powder, Feldspar Powder, aluminum oxide, copper powder, Graphite Powder 99, kaolin, talcum powder, iron powder again.Carbon fiber, resol ethanolic soln and fleut carry out drying treatment again after the banburying jar mixes, carry out hot compression molding with the metal liner.The metal liner will be through shot peening, washing, gluing and drying before hot compression molding.
Positively effect of the present invention be carbon fiber through cut off and the resol ethanolic soln mix the back add the abundant banburying of fleut mix after and the metal liner through hot compression molding.The existing carbon-to-carbon fibre vehicle stopper brake lining of Sheng Chaning all belongs to two carbon fibers, is higher than semi-metallic brake friction linings in cost height, high temperature resistant, work-ing life.And single carbon fiber product cost is low, the life-span long and the heat resisting temperature height.Carbon fibre friction facing for brake device is to adopt carbon fiber to do the main body strongthener, because carbon fiber physical strength in 2000 degrees centigrade is unattenuated, and have with temperature rising frictional coefficient and also slightly raise and stable properties thereupon, braking ability is not subtracted, be particularly suitable for running at high speed, frictional coefficient is about 0.45.
Fig. 1 is a process flow sheet of the present invention.
Embodiments of the invention are as follows:
Adopt resene to do matrix, PAN-based carbon fiber is done toughener, some different ratios mineral powder are done friction modifiers, its concrete proportioning and technology are, get polyacrylonitrile carbon fiber 5-15% by its weight ratio, it is standby to scatter through cut-out, 1: 1 the ratio of resol 20-30% and ethanol of getting is dissolved, treat to carry out thorough mixing with carbon fiber in the banburying jar behind the phenol resin solution, fleut is by barium sulfate 6-20%, chromite powder 5-10%, Feldspar Powder 10-15%, aluminum oxide 2-6%, copper powder 6-30%, Graphite Powder 99 2-15%, kaolin 2-10%, talcum powder 2-5%, iron powder 15-20% forms.After mixing, add in the banburying jar and mix, mix after 80 ℃ temperature is carried out drying treatment with carbon fiber and resol ethanolic soln.The carbon fiber mixed condensation material of metal liner after shot peening, washing, gluing, dry back and drying processing carries out hot compression molding, the temperature requirement of hot compression molding is about 250 ℃, liner behind the hot compression molding is through thermal treatment, thermal treatment temp requires about 200 ℃, time is 2 hours, promptly makes carbon fibre friction facing for brake device after mechanical workout.
