| titleOfInvention | Lignin epoxy resin/carbon fiber reinforced anti-aging composite material |
| abstract | The invention provides a lignin epoxy resin/carbon fiber reinforced anti-aging composite material, which is obtained by crosslinking and curing lignin epoxy resin and a carbon fiber material, and the strength of the obtained composite material can be still higher than that of a common bisphenol A epoxy resin/carbon fiber composite material under the condition that the use amount of carbon fibers is reduced by about 15%. A certain amount of polyacrylate polymer with glycidyl ether groups is added in the preparation of the lignin epoxy resin, so that the affinity of the lignin epoxy resin and carbon fibers is enhanced, the weather resistance of the obtained composite material is further enhanced, the retention rate of the mechanical property strength of the composite material is high in 30 days under high-humidity and high-heat environments, and the special requirements for working under the high-humidity and high-heat environments can be met. The lignin epoxy resin/carbon fiber reinforced anti-aging composite material provided by the invention has the advantages of reduced cost, more environment-friendly raw materials and excellent weather resistance, and is very suitable for industrial production and commercial popularization. |
