Abstract
A carbon-base composition used as friction braking material is prepared from non-crystal metal fibres, non-silicon ceramic powder, coke or asphalt powder and adhesive through, preparing raw materials, screening, mixing die pressing, sintering and post-treating. Its advantages are high performance, and simple preparing process.
Description
The present invention relates to a kind of novel environment friendly friction braking material.
Friction braking material is mainly used in automobile, tank, and the brake pair of the high speed traffic tool such as aircraft requires the friction braking material can be in the extremely short time, and the kinetic energy that rapid is powerful converts heat energy to and distributes.Therefore not only require it at high temperature physics and chemical property keep stable, also require it can bear hundreds of high temperature impacts and mechanical friction wearing and tearing, also require it and mating material in the brake pair not to bond simultaneously, braking back mating material still can freely rotate.Require friction braking material must possess following usability in order to satisfy these: high friction factor, good thermal conductivity, certain intensity, corrosion-resistant, wear-resistant, anti stick.The friction braking material that can possess above-mentioned performance at present substantially mainly contains: the metal-based powder metallurgy material. metallic beryllium and carbon/carbon compound material, they have his own strong points as braking material, deficiency is also all arranged, therefore except the material to present use improves, also be necessary to develop new friction braking material.
The present invention seeks to develop a kind of novel environment friendly friction braking material, its usability is good, makes simply, and with low cost, using scope is wide.
Key problem in technology of the present invention is: the composition of friction braking material and production technology thereof.Its composition is: amorphous metal fiber+no silicon ceramic powder+coke or asphalt powder+Bond.
Its production technology is as follows: at first make amorphous metal fiber, coke or asphalt powder and do not have the silicon ceramic powder, screening back adding additives mixes, sintering is carried out in compression moulding again, by reprocessing, finally obtain: amorphous metal fiber and no silicon ceramic powder are distributed in the composite material on carbon or the graphite matrix again.
The present invention is compared with the prior art: its feature is to use performance similar to carbon/carbon compound material, but manufacturing process simplifies greatly, and the manufacture cycle shortens greatly, and product cost reduces greatly, and free from environmental pollution.
Non-Si carbon-base non-crystal metal fibre composition is seen Figure of description.1 is the amorphous metal fiber among the figure, and 2 are no silicon ceramic powder, and 3 is carbon or graphite matrix.
Supplementary notes: non-Si carbon-base non-crystal metal fibre composition, because it is high temperature resistant, wear-resistant, corrosion-resistant, characteristics such as high specific strength, so also available and aviation, aerospace industry is made structure parts in addition.
