Research Progress and Prospect of Continuous Fiber Reinforced Metal Matrix Composites by Laser Additive Manufacturing
摘要
Abstract
Due to their high specific strength,high specific modulus,corrosion resistance,wear resistance and high temperature resistance,continuous fiber reinforced metal matrix composites are effective materials to reduce the weight of high temperature parts and improve mechanical properties.It has developed rapidly in the field of advanced materials and shows important application prospects in the aerospace field.Laser additive manufacturing processes and comprehensive properties of continuous fiber reinforced metal matrix composites are summarized in this paper.The process parameters,product microstructure and properties of continuous fiber reinforced titanium,nickel and iron matrix composites prepared by laser additive manufacturing are mainly reviewed.It is concluded that the limitation of laser additive manufacturing method to prepare continuous fiber reinforced metal matrix composites contains three aspects:(1)the fixation of continuous fiber.As the additive manufacturing process advances,the fiber departs from the initial position and the defocusing magnitude deviates,thereby influencing the heat input received by the fiber;(2)the preservation of fiber.As the reinforcing phase,the volume fraction of the fiber is not only associated with the properties of the composite materials but also directly determines the manufacturing cost of the composite materials;(3)the interface bonding between fiber and metal matrix.The interface of the composite material plays a decisive role in the load transfer process.Due to poor wettability,significant differences in the thermal expansion coefficient and elastic modulus between the fiber and the metal matrix,there exist issues of physical and chemical compatibility.Residual stress is generated from high-temperature cooling to room temperature,and internal cracks are prone to occur.The research ideas and solutions to the key problems include the utilization of wire laying devices to secure fiber and the regulation of additive manufacturing parameters to enhance the survival rate of the fiber.The future development of this field is prospected.Laser additive manufacturing technology has many advantages and great application potential,so this technology can be presented as one of the development directions of efficient preparation of continuous fiber reinforced metal matrix composites in the future.关键词
