摘要:

隨著各國航天工業(yè)的發(fā)展，飛行器朝著高馬赫數(shù)和長時間飛行發(fā)展，由此帶來的熱防護(hù)問題不容忽視，因此研究新型防熱材料以應(yīng)對嚴(yán)酷的飛行環(huán)境顯得十分重要。自20世紀(jì)50年代開始，樹脂基熱防護(hù)材料因其高殘?zhí)悸�、高防熱性能及低成本等�?yōu)點已經(jīng)成功應(yīng)用在美國與前蘇聯(lián)各類型號的導(dǎo)彈與火箭上。針對熱防護(hù)系統(tǒng)輕量化及防隔熱一體化的需求，總結(jié)了國內(nèi)外低密度樹脂基防熱材料的研究現(xiàn)狀，簡述了添加空心微球減重、構(gòu)造多孔結(jié)構(gòu)以及密度梯度纖維化設(shè)計等3種減重思路及逐漸從均一的低密度材料向梯度化材料演變的設(shè)計理念，展望了低密度樹脂基防熱材料的發(fā)展趨勢。

Abstract:

With the development of the aerospace industry in various countries, long period flight, bringing about the non-negligible thermal protection problem, which makes it significant to develop advanced thermal protection materials to cope with the harsh flight environment. Since the 1950s, resin-based thermal protection materials have been applied to various types of missiles and rockets in the United States and the former Soviet Union due to their high charring ratio, excellent performance of thermal protection and low cost. The research status of the low-density resin-based thermal protection materials has been systematically summarized. Three major lightweight strategies, including adding hollow microspheres, developing porous structures and designing 3D woven fiber preforms are introduced. Besides, the design concept of gradually evolving from uniform low density materials to gradient materials is introduced and the development trend of low-density resin-based heat-resistant materials is prospected.
