Abstract

The invention discloses a method for adopting a microwave ultrasound solidification fibre reinforced composite component and a special device thereof. The method comprises the following steps of: firstly placing a prefabricated part in a filling module, wherein the filling module simultaneously uses ultrasonic wave to accelerate a resin to permeate and increase the wettability; and using a microwave heating module after finishing until resin is full solidified. The special device is used for installing a mould in a microwave cavity, the microwave cavity is externally connected with a microwave generator, and the microwave cavity is internally provided with an ultrasonic transducer and is externally connected with an ultrasonic generator. The method and the special device provided by the invention solve the problems that when a fibre reinforced composite material is manufactured by using the traditional composite material forming method, the manufacturing time is long, the energy consumption is high, the fiber soakage is not full and a local region is not filled by a module, and the quality and performance of composite material parts are improved.

Description

[0001] technical field [0002] The invention belongs to the field of composite material molding and processing, and specifically refers to a method for solidifying fiber-reinforced composite material components by using microwave ultrasound and a special device thereof. Background technique [0003] Fiber-reinforced resin-based composite materials have high specific strength and specific stiffness, light weight, heat resistance, corrosion resistance, fatigue resistance, and good shock absorption performance. They are widely used in aerospace, transportation, wind power, and electronic power. and other fields. Prepreg is a prepreg sheet product made by impregnating reinforcing fibers (carbon fiber, glass fiber, aramid fiber) in a matrix (epoxy resin, polyester resin, thermoplastic resin, etc.). Intermediate material for matrix composites. [0004] Due to the above-mentioned excellent properties of fiber-reinforced resin-based composites, different molding methods have been...
