Abstract
The invention discloses a kind of dopey new brake friction plate based on polyimides, it is composed of the following components in parts by weight: copolymerization PMR polyimide prepolymer powder 20～25 parts, nitrile rubber powder 5～8 parts, chopped carbon fiber 6～9 parts, Fanglun slurry cake 2～3 parts, SiO 2 powder 15～20 parts, barium sulfate powder 20～25 parts, aluminium sesquioxide powder 5～7 parts, copper powder 3～5 parts, iron powder 5～7 parts, meerschaum 3～5 parts, Vermiculitum 3～5 parts, powdered graphite 2～3 parts, molybdenum disulfide powder 5～7 parts.Friction plate internal bond strength is high, adhesion strength is good, stable friction factor, wear rate is relatively low, and heat resistance is good, reduces heat fading phenomenon, it is not required to carry out anti-oxidation process, hygrometric state stable friction performance, improves friction plate torque transmission capacity under relatively elevated operating temperature and wet environment, effectively reduces manufacturing cost compared with carbon carbon brake.
Description
Technical field
The present invention relates to a kind of dopey brake disc Novel friction plate, belong to mechanical braking and control technical field.
Background technology
At present, aircraft bremsbelage mainly has carbon/carbon material and powdered metallurgical material two class.There is easy oxygen in carbon/carbon brake material
Change problem, the easy moisture absorption, the shortcomings such as hygrometric state coefficient of friction is low, and static friction coefficient is little, and volume is big, and production cost is high.Powder smelting
Gold brake material is deposited the most bonding, and weight is big, and service life is short, and heat fading is obvious, and elevated temperature strength declines notable, anti-
The shortcomings such as thermal shock ability.Therefore, it is necessary to for small-sized dopey brake disc friction material, exploitation one is avoided above
Defect, the new brake friction plate formula of high comprehensive performance.
Summary of the invention
For solving the deficiency that existing aircraft drag friction sheet material exists, the technical problem to be solved in the present invention is, proposes one
Dopey new brake friction plate formula, it is possible to stablize dry state and hygrometric state coefficient of friction, reduces wear rate, improves heat resistance,
Weakening heat fading phenomenon, antioxidation is excellent.
The present invention adopts the technical scheme that, a kind of dopey brake disc friction plate, is composed of the following components in parts by weight:
Copolymerization PMR polyimide prepolymer powder 20～25 parts, nitrile rubber powder 5～8 parts, chopped carbon fiber 6～9 parts, aramid fiber
Pulp 2～3 parts, SiO 2 powder 15～20 parts, barium sulfate powder 20～25 parts, aluminium sesquioxide powder 5～7 parts, copper powder
3～5 parts, iron powder 5～7 parts, meerschaum 3～5 parts, Vermiculitum 3～5 parts, powdered graphite 2～3 parts, molybdenum disulfide powder 5～7 parts.
The advantage of a kind of dopey new brake friction plate formula based on polyimides of the present invention is:
1) stable friction factor, wear rate is relatively low, stable friction performance under hygrometric state operating mode；
2) heat resistance is good, reduces heat fading phenomenon, is not required to carry out anti-oxidation process；
3) manufacturing cost is effectively reduced compared with carbon carbon brake
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.
Embodiment 1:
A kind of dopey bremsbelage, is composed of the following components in parts by weight: copolymerization PMR polyimide prepolymer powder
23 parts, 6 parts of nitrile rubber powder, chopped carbon fiber 6 parts, Fanglun slurry cake 2 parts, SiO 2 powder 15 parts, barium sulfate
20 parts of powder, 5 parts of aluminium sesquioxide powder, copper powder 3 parts, iron powder 5 parts, meerschaum 4 parts, Vermiculitum 4 parts, powdered graphite
2 parts, molybdenum disulfide powder 5 parts.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the art general
Logical technical staff, in the essential scope of the present invention, the change made, retrofits, adds or replaces, should belong to the present invention's
Protection domain.
