Portable device for preparing fiber reinforced composite material and using method of device

Abstract

The invention provides a portable device for preparing a fiber reinforced composite material and a using method of the device. One side face of a fixed support plate and one side face of a movable support plate are opposite; threaded holes uniformly distributed are formed in each of the opposite side faces of the fixed support plate and the movable support plate; all the threaded hole in the fixedsupport plate and the movable support plate are corresponding pairwise in position; each pull ring is provided with threads; the pull rings are fixed by the corresponding threaded holes in the fixedsupport plate and the movable support plate; an opening is formed in each of pairwise opposite ends of the pull rings; and the openings are used for twining a fiber material. The device provided by the invention is simple in structure, low in manufacturing cost, has a low demand on the operating skill of operating personnel, and is easy to use; processing can be performed as needed according to different specifications; an electromagnetic inductor is capable of accurately controlling sensitivity and the force measuring range of the device, so that error brought by the device is reduced; distribution of an internal force is more uniform after the material is molded by the device, so that mechanical property of the material is improved.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a composite material preparation device and a method for using the device. Background technique [0002] Fiber-reinforced composites have many advantages and are widely used in daily life and military fields as the technology matures. Fiber-reinforced composite materials have high specific strength and specific stiffness, good fatigue resistance and vibration damping performance; mechanical properties can be designed, that is, synthetic material components or composite material structures can meet the use requirements by selecting appropriate raw materials and reasonable lay-up forms . [0003] At present, there are three main methods of stretching and preparing fiber materials in the market: [0004] (1) Piezoelectric-based cantilever beam: This device is coupled to an electro-optical microscope, which can realize in-situ mechanical performance testing, and combine quantitati...

AI Technical Summary

Problems solved by technology

[0007] The devices used in the above preparation methods are complex in structure and high in cost. The preparation requires high operating skills and high labor intensity, and it is difficult to control the tension of the fibers, which will easily lead to uneven distribution of the internal stress of the fibers after forming the product, resulting in Poor mechanical properties
