Study of New Electron Beam Surfi-sculpt Manufacturing Technology during Composite Materials Joining

摘要

Electron beam surfi-sculpt is a new metal surface processing technology, which is widely used in the areas of materials surface treatment, composite materials manufacturing, and so on. In this paper, comeld technology, which was an application technology of electron beam surfi-sculpt during composite materials area, was introduced. And tensile experiments results and failure forms of Ti6Al4V/Carbon fibre single step joints were compared with different joining methods, such as slick embedding, adhesive bonding, riveting and comeld. It was found that comeld joint had more advantage of tensile property than other joining methods. At the same time, tensile process of comeld joint was analysed with numberical simulation, and key factors of protrusions influenced tensile property were obtained, which was of importance to structure design and joint property improvement.
