埃洛石纳米管改性碳泡沫复合材料的性能研究
Properties of HNTs modified carbon foam composites
摘要
Abstract
To optimize carbon foam composite properties,this study synthesized Halloysite Nano-tubes(HNTs)-modified carbon foams via one-step high-temperature carbonization,using zirconi-um-modified phenolic resin as precursor,closed-cell hollow microspheres as dispersed phase,and HNTs as reinforcing phase.The effects of HNTs content(0~8%)on the foam's compressive properties and high-temperature ablation resistance were systematically studied.Results showed that increasing HNTs content improved the modified foam's mechanical properties.Specifically,the foam with 6%HNTs achieved a compressive strength of 13.4 MPa,an 81.1%increase over pure carbon foam(7.4 MPa).It was attributed to effective interfacial bonding between dispersed HNTs and the carbon matrix,as well as synergistic reinforcement by HNTs and hollow micro-spheres to inhibit crack propagation.The modified foams also exhibited excellent high-tempera-ture ablation resistance.After 240 s of ablation,in-situ generated surface ceramic phases(e.g.,SiO2)provided a significant thermal barrier effect,delaying thermal oxidative spallation and crea-ting a temperature difference of over 700 ℃ between the ablated and back surfaces.The introduc-tion of HNTs with varying contents,improved the mechanical properties and anti-ablation stabili-ty of carbon foam composites,providing potential value for the development of aerospace thermal protection materials.关键词
