Epoxy Resin Composites

Description

Epoxy resin is the most widely used resin system in advanced composites. Epoxy resins have excellent properties that can be adapted to different production processes, and the cured products have excellent stability, good heat and humidity resistance, and high insulating properties. Currently epoxy resins rule the market for high performance composites.

Epoxy resin raw materials used in epoxy resin composites

The most used epoxy resin in the composites industry is glycidyl ether epoxy resin, which is dominated by bisphenol A epoxy resin. Followed by glycidyl amine epoxy resin and glycidyl ester epoxy resin. Others are phenolic epoxy resin, epoxy acrylic resin and alicyclic epoxy resin and so on.

Application of epoxy resin composites

Epoxy resin composites in the chemical industry

Epoxy resin composites have been widely used in industries such as petroleum, fertiliser, salt production, pharmaceuticals, papermaking, seawater desalination, bioengineering, environmental engineering and metal plating.

Epoxy Resin Composites in the transport and energy industries

In the transport industry, it is mainly used in the road, railway, marine and aviation construction industry in the automobile manufacturing industry. And in the energy industry, it is mainly used in ventilation systems in the thermal power generation industry, coal ash discharge pipelines, circulating water cooling systems, power station construction, wind turbine blades, poles and electrical insulation products.

Epoxy resin composites in the mechanical and electrical industry

The mechanical and electrical industries, traditionally made of metal materials, can now be manufactured with resin matrix composites for a higher benefit/cost ratio.

Epoxy resin composites in the electronics industry

Composite materials have many excellent properties, have been widely used in the electronics industry. The most representative epoxy resin composites are the printed circuit board substrate materials and the production of a variety of antenna feeder. At the same time the use of some composite materials, wave-absorbing properties, can also be made of shielding materials and stealth materials.

Epoxy composites in medical and sports and recreational industry

In biocomposites, composites can be used to make artificial hearts, artificial lungs and artificial blood vessels, etc. The idea of saving lives with artificial composite organs will become a reality. Composite fishing rods are the bulk of recreational equipment. And in the manufacture of musical instruments, high-performance composite materials have been promoted and applied.

Epoxy composites in national defence and military and aerospace industry

For aerospace flights and their safety considerations, the structural material should be lightweight, high strength, high reliability and stability epoxy carbon fibre composites become indispensable materials.

Development of epoxy resin composites

Composite products have also been requested to be lightweight, wear-resistant, corrosion-resistant, low-temperature-resistant, high-temperature-resistant, and oxidation-resistant. And it is requested to be Low-cost, including raw materials, composite process and quality control and other aspects. And it is also requested to be multifunctionalisation. As aerospace advanced composite materials are gradually realising the integration of structure and function by pure structure type.
