Abstract

The invention discloses a continuous preparation device for a conductive micro-nano material modified prepreg. The continuous preparation device comprises a fiber tow unfolding device, a fiber dipping glue tank, a prepreg thickness adjusting roller set, a high-voltage direct-current power supply and a prepreg winding device. An ultrasonic probe is arranged in the fiber impregnation tank, and uniform dispersion of a conductive micro-nano material in a resin glue solution is mainly realized; the high-voltage direct-current power supply is mainly used for constructing a high-strength uniform electric field, and directional control on the conductive micro-nano material is achieved through an electric field orientation method. While the yield of the conductive micro-nano material / fiber reinforced thermosetting resin-based prepreg is increased, the problems of agglomeration and random dispersion of the conductive micro-nano material in the resin are solved, and the device has a positive effect on improvement of the performance of the composite material.

Description

technical field [0001] The invention belongs to the field of preparation of micro-nano modified composite materials, in particular to a continuous preparation device for conductive micro-nano material modified prepreg. Background technique [0002] Fiber-reinforced resin-based unidirectional composites have excellent mechanical properties in the fiber direction, but unidirectional composites have problems such as low strength and weak impact damage resistance in the direction perpendicular to the fibers due to the constraints of the resin matrix and fiber-resin interface properties. , which greatly reduces the design flexibility of composite materials and restricts their application in multifunctional engineering components. Fiber-reinforced resin-based prepreg is the basic unit of unidirectional laminates, and its modification is the key to optimize and improve the comprehensive performance of composite materials.
