The development of science and technology has led to the gradual obsolescence of many traditional processes and materials, making new technologies and materials essential to meet the needs of social production. High-quality materials like carbon fiber tubes are becoming the choice for many industries. Moreover, carbon fiber tubes possess unparalleled advantages over other materials, including light weight, high specific strength, high specific stiffness, high temperature resistance, friction resistance, fatigue resistance, and good design flexibility.
The processing of carbon fiber tubes requires specific techniques for different applications, but the most common process is drilling holes in them. To meet processing requirements, careful attention must be paid to hole machining, as defects are prone to occur during this process, with delamination being the most common. What exactly are these details?
First and foremost is the issue of delamination. Delamination of carbon fiber tubes is easily caused during hole machining. Drilling force and heat can cause delamination. When the axial drilling force acts on the stress between the fiber layers of the carbon fiber tube, if the stress exceeds the strength of the resin between the fiber layers, the resin will break, leading to delamination. Another delamination phenomenon is the increased temperature at the contact point between the tool and the resin. Due to the different coefficients of thermal expansion between carbon fiber and resin, the boundary stress caused by the thermal effect becomes excessively concentrated, resulting in localized strain and delamination.
