A portable fiber-reinforced composite material preparation device and its use method

Abstract

The invention provides a portable fiber-reinforced composite material preparation device and its use method. The two sides of the fixed support plate and the movable support plate are opposite to each other, and uniformly distributed threads are arranged on the opposite sides of the fixed support plate and the movable support plate. holes, and the positions of all the threaded holes on the fixed support plate and the movable support plate correspond to each other. Each pull ring has threads, and the pull rings are respectively fixed by the threads on the fixed support plate and the movable support plate. The opposite end is provided with an opening for winding the fibrous material. The invention has the advantages of simple structure, low manufacturing cost, low requirements on the operating skills of operators, easy to use, and can be processed according to different specifications according to requirements. The electromagnetic inductor should be able to accurately control its sensitivity and force measurement range, and reduce the error caused by the device. , The device makes the internal force distribution of the material more uniform after forming, and improves the mechanical properties of the material.

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...

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
