Prospects for the development of copper-plastic composite belts starting from damping performance, friction reduction and wear resistance
Mar 15, 2018

When it comes to the prospects for the development of copper-plastic composite tapes, it actually refers to the predicament that the copper-plastic composite belt is currently facing. Afterwards, it should be the direction in which efforts should be made, or whether the copper-plastic composite tape is currently in a better position, and it should be followed by more progressive aspects. This also includes strong vibration-reducing properties of copper-plastic composite tapes, friction reduction, wear resistance, self-lubrication, and high heat resistance.

 

The copper-plastic composite tape itself has relatively strong vibration-reducing performance, and the natural vibration frequency of the structure has a great relationship with the shape and quality of the structure itself and is proportional to the square root of the specific modulus of the material. The fiber-reinforced composite material has a large specific modulus and a relatively high natural frequency, which avoids early damage caused by resonance under working conditions. At the same time, the fiber and matrix interface in the copper-plastic composite belt has the capability of absorbing vibration. Because of this, the vibration damping itself is relatively high, and even if resonance occurs, it will decay rapidly.

 

The anti-friction, wear-resisting and self-lubrication properties of the copper-plastic composite tape are good. Adding a small amount of short-cut carbon fiber into the thermoplastic plastic can greatly improve its wear resistance. The increase factor is 3.8 times that of PVC itself. Teflon itself 3 times.

 

The carbon-fiber-reinforced plastics used in copper-plastic composite tapes can also reduce the coefficient of friction of plastics, and then they can also have good self-lubricating properties. Because of this, they can also be used to make oil-free lubricating piston rings, bearings and gear.

 

The copper-plastic composite tape also has a relatively high heat resistance, because it is a metal matrix composite material, and it shows better performance in terms of heat resistance. The copper-plastic composite tape can withstand temperatures of 1200-1400°C in the air. , more than 100°C higher than the heat resistance of all ultra-high temperature other fiber materials. However, on the prospect of the development of such a copper-plastic composite tape, it is also necessary to pay attention to this aspect should be more prominent in order to expect to meet the use of various working environments. http://www.copolymercoatedaluminumtape.com
