Abstract

The invention discloses a radial yarn implantation mechanism of a three-dimensional braided prefabricated body, belonging to the technical field of three-dimensional braiding. Three-dimensional braided prefabricated radial yarn implantation mechanism, including: upper support, upper linear actuator, upper support mechanism, upper yarn implantation device, yarn end carrying device, upper ring gear, lower yarn Wire implantation device, lower linear actuator, bracket, lower ring gear, lower gear, lower motor, lower circular track, upper circular track, base, upper gear, pneumatic transmission and control device, and upper electric motor. The radial yarn implantation mechanism of the three-dimensional braided preform of the present invention has the characteristics of high braiding efficiency and automatic radial yarn implantation.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional braiding machines, and in particular relates to a radial yarn implantation mechanism of a three-dimensional braiding prefabricated body. Background technique [0002] Three-dimensional braided composite material is a new type of composite material, which has a complex network structure composed of yarns in multiple directions, and it can be used as a reinforcement of composite materials to avoid the large interlayer bonding defects of traditional composite materials. The problem. In addition, the introduction of radial yarns can increase the direction of the yarns in the preform. In addition to improving the performance of the original weaving direction, it can also improve its in-plane performance and obtain more excellent performance. However, at present, the introduction of radial yarns is mainly carried out manually, and it is difficult to ensure the consistency of prefabricated bod...
