Composite material for connecting parts

Abstract

A novel composite material for preparing connecting pieces comprises, in percent by mass, 4-8% of aluminium particle, 6-12% of carbon nanoparticle, 24-35% of low-viscosity polyamide, 13-25% of glass fiber, and 33-52% of epoxy resin. A connecting piece prepared by employing the above composite material has mechanical strength, hardness and other performances similar to those of cast iron, the mass is reduced by 40%-50%, and the connecting piece is excellent in mechanical performances, and is simple in manufacturing and installation. The production cost is reduced and the composite material is suitable for wide popularization.

Description

Technical field [0001] The present invention relates to the field of materials, in particular, to a composite material for manufacturing a new type of connector. Background technique [0002] Connectors are often required in the mechanical field. For example, in pipe connections, connectors such as snap-in connection structures are usually used. In the prior art, the connectors such as the above-mentioned snap-in connection structure are usually made of cast iron or stainless steel, but their weight is heavy and there are many inconveniences in manufacturing and installation. Although some existing connectors are also made of aluminum Alloys are used for manufacturing, but its cost is usually high, and its mechanical strength is still different from that of cast iron or stainless steel connectors, which cannot be used on a large scale. Therefore, there is an urgent need for a connector made of a new material with light weight, high strength and low cost to meet the needs of easy...

Problems solved by technology

In the prior art, the connectors of the above-mentioned snap-in connection structure are usually made of cast iron or stainless steel, but their weight is heavy, and there are many inconveniences in manufacturing and installation. Although some existing connectors are made of aluminum Alloys are used for manufacturing, but the cost is usually high, and there is a certain gap between its mechanical strength and the connecting parts made of cast iron or stainless steel, so it cannot be used on a large scale.
