Which of epoxy resin and phenolic resin has better performance as a matrix composite material? I recently found a topic about the impact of sulfide, graphite, and coke as pore-forming materials on the overall performance of the material. I don’t know which resin to choose as the matrix. Note: I am working on friction materials. This post was last edited by QXZ-1966 on 2009-3-30 18:40 ]
It still depends on which performance LZ needs to be used for. Phenolic resin is very common as a friction material matrix. For example, brake pads use phenolic composite materials. Epoxy resin has good corrosion resistance, a wide selection of curing agents, and a wide curing temperature range. It is mostly used in flooring, electronic packaging, anti-corrosion coatings, etc. LZ can consider it himself.
Generally, phenolic resin is used, and epoxy resin is also modified. Mainly due to temperature resistance considerations
Phenolic resin is relatively cheap, has low water absorption, good ablation resistance, and good electrical insulation, so it is widely used in electrical insulation materials and ablation-resistant materials. Epoxy resin can be modified in terms of corrosion resistance, temperature resistance, and wear resistance, but the price is higher. This post was last edited by zhouchu2001 on 2009-4-10 09:19 ]
Phenolic resin is famous for its friction resistance, and it is also cheap. If you consider the cost, you can use phenolic resin as the base. You just need to consider whether the compatibility is good when used with materials such as graphite. For friction materials, the compatibility of modified materials is still very important.
Maybe the effect of epoxy resin is better because it has good compatibility with the sizing agent and is conducive to the adhesion of reinforced materials.
