Abstract
Disclosed in the present invention is a microfiber high-energy implantation device for manufacturing three-dimensional carbon fiber reinforced composites, wherein the device comprises: a micro fiber feeding module, a micro fiber orientation arrangement module, a micro fiber electrifying module, a micro fiber accelerator injection module, a vacuum generator module, a high-voltage electrostatic acceleration module, an accelerator bunching module, and a micro fiber extraction control module. The present invention uses the large scale micro fibers subjected to charging treatment and reaching scale requirement of the target charge-mass ratio as the fiber source for high-energy implantation, and uses the high-voltage electrostatic acceleration electric field to accelerate and energize the array large-scale micro fibers which are uniformly and directionally arranged, so that the speed and energy thereof can meet the implantation requirement. The output kinetic energy of the micro fibers is used to inject them into the target reinforcement area of the prepreg of the two-dimensional laminate structure to realize the fabrication of three-dimensional carbon fiber reinforced composites.
