摘要
碳纤维复合材料具有耐高温、耐摩擦、耐腐蚀等诸多优异性能,被广泛应用于航空航天、汽车制造等相关领域。鉴于碳纤维复合材料的广泛应用,制备碳纤维复合材料构件的自动铺放设备及技术也得到了快速发展。近年来,复合材料自动铺放技术也取得了非常显著的成绩。碳纤维复合材料自动铺放技术的研究是铺放设备、铺放轨迹、铺放工艺及铺放软件技术的综合性研究。其中,研究人员将铺放头与纤维纱架结合实现了碳纤维复合材料铺放设备的一体式结构,为完全自动化铺放奠定了基础。碳纤维复合材料的铺放轨迹起初采用相对简单的定角度铺放,但是近些年变角度铺放成为研究热点,采用变角度铺放可以提升铺放构件的力学性能。另外,工作人员针对复合材料的铺放温度、铺放速度和铺放压力等铺放工艺进行了研究,实现了铺放工艺参数的优化并提高了铺放构件的成型质量。此外,在复合材料自动铺放软件技术的研究中,研究人员以铺放工艺及构件形体要求为基础,开发了与铺放设备相匹配的CAD/CAM软件系统,实现了复合材料的自动化、智能化铺放。本文主要从自动铺放设备结构、纤维铺放轨迹规划与控制、铺放工艺参数优化和自动铺放软件系统几个方面对国内外自动铺放技术的研究进展进行了综述。基于自动铺放技术的发展现状,总结了国内自动铺放技术存在的问题,并对国内自动铺放技术的发展方向进行了探讨。
Carbon fiber composite materials have many excellent properties such as high temperature resistance,friction resistance and corrosion resistance,which are widely used in aerospace,automatic manufacturing and other related fields.In view of the wide application of carbon fiber composite materials,automated placement equipment and technology for preparing carbon fiber composite materials have also been rapidly developed.In recent years,remarkable achievements have been made in the field of automated placement of composite materials.The research on automated placement technology of carbon fiber composite materials is a comprehensive study of placement equipment,placement trajectory,placement technology and placement software technology.Among them,the researchers combined the placement head with the fiber creel to realize the integrated structure of the carbon fiber composite placement equipment,which provides the basis for fully automated placement.At first,the placement trajectory of carbon fiber composite materials used relatively simple fixed-angle placement,but in recent years,variable-angle placement has become a research focus,which can improve the mechanical properties of placement components.In addition,the researchers studied the placement process of composite materials,such as placement temperature,placement speed and placement pressure,realized the optimization of placement process parameters and improved the forming quality of placement components.In addition,in the research of composite material automated placement software technology,based on the placement process and component shape requirements,the researchers developed a CAD/CAM software system matching the placement equipment to realize the automation and intelligence placement of composite materials.This paper reviews the research progress of automated placement technology at home and abroad focusing on the structural applicability of automated placement equipment,fiber placement trajectory planning and control,optimization of placement process parameters and automated placement software systems.Based on the development status of composite automated placement technology,the existing problems of composite automated placement technology in China are summarized,and the development trend direction of composite automated placement technology is discussed.
