Embodiment

[0021] Example: see figure 1 , figure 2 and image 3 . figure 1 It is a structural schematic diagram of the damping tension control device used to ensure the length consistency of the fiber precursors before plying, including the precursor cylinder 100, the tension control wheel 200, the pressing wheel 300 and the plying wheel 400. After each fiber precursor is pulled out from the precursor tube, it enters the corresponding tension control device respectively. The tension control device includes two parts: the tension control wheel 200 and the pressure wheel 300; The filaments are subjected to uniform tension, and finally enter the ply wheel 400 for plying to obtain ply yarn 500.

[0022] figure 2 It is a schematic diagram of a tension control wheel 200 with a damping control device. The tension control wheel is composed of a damping control device 1 and a tension wheel 2. The damping control device 1 uses an electromagnetic damper or other types of dampers. Set differe...

Abstract

The invention provides a silvalin plying device and method for improving mechanical properties of fiber reinforced composite materials. The plying device comprises a silvalin releasing frame, a plying wheel and a damping type tension control device, wherein more than two precursor silvalin barrels are arranged on the silvalin releasing frame, concentric circular grooves for precursor silvalin plying are formed in the whole periphery of the plying wheel, the damping type tension control device comprises a tension control wheel and a pressing wheel, the tension control wheel comprises a damping control device and a tension wheel, the damping control device is connected with a wheel shaft of the tension wheel to control the rotation sped of the tension wheel, and the pressing wheel acts on precursor silvalin on the surface of the tension wheel adjustably. The silvalin plying method is simple in structure, is convenient to operate, overcomes the bottlenecks that part of fibers are twisted and are not uniform in length when a plurality of the precursor silvalin fibers are plied, and resolves the problems that due to the fact that the inside fibers are twisted and are not uniform in length after plying of the precursor silvalin fibers, the joint stress work performance of the fibers in a plied yarn is poor.

Description

technical field [0001] The invention relates to a process device and method for improving the mechanical properties of fiber-reinforced composite materials, in particular to a plying device and method with a damping tension control device that ensures the consistency of the length of fiber precursors before plying. Background technique [0002] Fiber-reinforced composite materials have been widely used in civil engineering transportation, energy and environmental infrastructure, aviation, sporting goods and other fields due to their excellent properties such as light weight, high strength, and corrosion resistance. The mechanical properties of fiber-reinforced composites are determined by the fibers, the matrix, and the interface between the two. Since fibers are the main reinforcing material, the level of mechanical properties and the uniformity of stress will dominate the overall mechanical properties of fiber-reinforced composites. Fiber-reinforced composite materials are...
