摘要
炭泡沫是一种由孔泡和相互连接的孔泡壁组成的具有三维网状结构的多孔材料,具备强度高、密度低、热电性能可调、热膨胀系数低、耐高温、可设计性强、易加工等特点。用其做成的树脂基复合材料成型模具在模具制造、质量、变形、可维修、运输等方面都具有明显优势。文中先综述了模具用炭泡沫材料和炭泡沫模具技术发展,然后与传统模具对比说明炭泡沫模具的性能优势,进而对炭泡沫模具设计和制造中的关键技术进行归纳,最后对国内开展炭泡沫模具的研发提出建议。
The coal-based carbon foam is open cell,porous carbon with interconnected pores and possesses characteristics such as high strength,light weight,tailorable thermal and electrical conductivity,low coefficient of thermal expansion(CTE),high temperature resistant,strong designability and machinability,etc.,which shows tremendous advantage over other materials when used to manufacture carbon foam-based polymer matrix composites tooling products.In this paper,firstly,the development of carbon foam was reviewed.Secondly,the development of carbon foam tooling was reviewed.Thirdly,the properties of carbon foam tooling were summarized.Fourthly,the key techniques in the design and manufacture of carbon foam tooling were generalized.Finally,some suggestions for the investigation of carbon foam tooling were put forward.
