Abstract: Aiming at the disadvantages of complex structure and high manufacturing cost of the existing fiber stretching device, in order to ensure the tension on each bundle of fiber is controlled precisely during the process of fiber stretching and the properties of fiber products are guaranteed,a convenient fiber reinforced composite preparation device is designed in this paper. This device can ensure the accuracy of the stretching movement trajectory, and can be freely telescopic, which can not only increase the working width of the material stretching, but also shrink to make the size smaller. Build its 3D model in SolidWorks, and then in the finite element analysis software ANSYS stiffness, strength simulation analysis, optimization and verification of the design scheme, simulation results show that the stiffness and strength of the device meet the requirements of use.
