AI Technical Summary
The poor compatibility between carbon nanomaterials and resin matrix leads to uneven dispersion and poor stability of the repair material. Phenolic resin has low strength, high brittleness and poor toughness, and is prone to cracking under alternating loads, making it unable to self-repair microcracks.
By mixing phenolic resin with cashew phenol benzoxazine resin and adding modified multi-walled carbon nanotubes, functional fillers, defoamers, leveling agents and antioxidants, and using a composite catalyst for high-speed dispersion and vacuum desolventizing treatment, an in-situ reinforced shaft-type repair carbon nanopolymer material was prepared. The modified multi-walled carbon nanotubes were loaded with bis-[3-(triethoxysilyl)propyl]tetrasulfide by negative pressure method and modified with titanate coupling agent. Cashew phenol benzoxazine resin was catalytically ring-opening polymerized during co-curing of the mixed resin to form a network interpenetrating structure.
It improves the toughness, wear resistance and self-healing ability of carbon nanopolymer materials, enhances the bonding force and crack propagation resistance of materials, reduces stress concentration, and achieves high toughness and low shrinkage performance.
