Bonding process of carbon fiber and metal plate assisted by ultrasonic vibration

Abstract

The invention discloses a carbon fiber and metal plate gluing process based on ultrasonic vibration assistance. The process comprises the following steps: a carbon fiber plate and a metal plate are placed in a positioning fixture; the metal plate is placed above the carbon fiber plate; the metal plate is heated to reach 75-85% of a glue film softening temperature; a glue film is paved in a gluing area between the metal plate and the carbon fiber plate; intermittent ultrasonic vibration is applied to an appointed area of the carbon fiber plate through an ultrasonic vibration tool head, and meanwhile, the metal plate is continuously heated; the ultrasonic vibration tool head is ascended; and a gluing piece and the positioning fixture are placed in an air blowing drying box by a period of time for curing. The carbon fiber and metal plate gluing process based on ultrasonic vibration assistance prevents the problem of nonuniform glue film curing degree and glued surface gluing strength caused by nonuniform glue film heating due to a high-temperature pressing head heat transfer mode.

Description

technical field [0001] The invention relates to the technical field of bonding, in particular to a bonding process based on ultrasonic vibrations assisting carbon fibers and metal plates. Background technique [0002] Adhering to the promotion of green sustainable development and vigorously promoting energy conservation, emission reduction and consumption reduction are important guiding ideologies of the "National Twelfth Five-Year Plan". Lightweight is one of the important methods for energy saving and emission reduction. Carbon fiber reinforced plastic / polymer (CFRP) has become a deeply lightweight The material of choice for primary and secondary structural parts has grown rapidly in applications such as large aircraft, wind power blades, auto parts, oil extraction sucker rods, and power transmission cables, making important contributions to the realization of national goals for energy conservation and emission reduction. [0003] The wide use of carbon fiber composite ma...
