Description
[ field of technology ]
The invention relates to a weaving device and a weaving method of a fabric, in particular to a weaving device and a weaving method of a woven fabric with a gradient structure, which can ensure that structural differences are formed in an intra-layer axial direction, an intra-layer circumferential direction and an inter-layer radial direction, and belong to the technical field of textile machinery.
[ background Art ]
The tubular composite material is widely applied to the fields of fire fighting, pipeline repair, medical treatment, aerospace and the like due to the excellent comprehensive properties, such as light weight, excellent fatigue resistance, high specific strength and specific rigidity, good corrosion resistance and the like. Braiding is a method for producing a seamless hollow woven fabric, which is formed by interlacing two sets of yarns with each other and accumulating on the surface of a mandrel, and a tubular composite material can be prepared by injecting a high molecular polymer into the woven fabric. Reinforcing fabric structures have a direct impact on the performance of the composite, generally using the weave angle as a descriptive indicator of its structure. The braiding in the current braiding composite material adopts a uniform structure, namely the braiding angle in the component is a fixed value.
For fiber reinforced composite materials (such as carbon fiber reinforcement), although the fiber reinforced composite materials have the characteristics of high specific strength/modulus, excellent corrosion resistance and the like, the higher price is a main obstacle affecting popularization and application, and in the case that the fiber price cannot be obviously reduced in a short period, the improvement of material utilization by reasonably designing the material distribution is an important means. In recent years, functional gradient materials have attracted a great deal of attention, and the physical and chemical characteristics of the materials are continuously changed in a gradient manner in a certain direction, so that the macroscopic performance of the materials is determined to be changed in a gradient manner in the direction, different requirements of different parts of the structural element on the use performance of the materials are met, and the purpose of optimizing the integral use performance of the structure is achieved.
According to different loads, reasonable design has intra-layer axial structure, intra-layer circumferential structure and inter-layer radial structure gradient difference, and has very important significance for improving the utilization rate of materials. For example, when the composite material pipe is woven by an axial gradient structure with monotonically increasing weaving angle and bearing axial load, the damage mode of the woven fabric is gradually changed from tearing from a small angle to a large angle, and the tearing process of the woven fabric can absorb most energy so as to improve the utilization rate of the material. When the composite material pipe with the double-layer radial gradient structure, which has the advantages of large inner layer braiding angle and small outer layer braiding angle, bears three-point bending load, the load can be rapidly and uniformly dispersed to the whole braided pipe along the axial direction due to the small outer layer braiding angle and the trend of the fiber direction to the axial direction; the inner layer of the composite material pipe has large braiding angle and high fiber content, and can bear main load, so that the gradient structure braided composite material pipe has better performance compared with a uniform structure.
In the process of forming a composite fibre reinforcement, the woven reinforcement is produced by rotation of a carrier in an annular braiding machine and movement of a mandrel. Currently existing annular braiding machines are used to produce uniform structural reinforcements with constant braiding angles. The change of the axial braiding angle can be realized by changing the rotation speed of the yarn carrier and the extraction speed of the mandrel in the braiding process. However, in the actual knitting process, since the two groups of yarn carriers rotate around the clockwise and counterclockwise directions to form knitting yarns which are interwoven with each other, the rotation speed is relatively high, the kinetic energy is relatively high, and the sudden change of the speed can increase the abrasion of the yarn carriers and cause the increase of friction force between yarns to cause the breakage of the yarns. However, for the axial gradient structure with a specific angle change rule, it is difficult to accurately and rapidly change the mandrel extraction speed to the extraction speed corresponding to the angle change rule. Secondly, although the reciprocating movement of the mandrel can weave the multi-layer fabric, the existing annular braiding machine is difficult to realize the automation of the reciprocating extraction of the mandrel and the controllable gradient change between the layers of the multi-layer fabric, and cannot realize the circumferential gradient change in the layers of the braided fabric. Therefore, the controllable, accurate and effective annular braiding device capable of braiding the structural gradient reinforced fabric has great significance for realizing braiding of the structural gradient circular tube type braided reinforced fabric in the axial direction, the circumferential direction and the radial direction.
Accordingly, to solve the above-mentioned problems, it is necessary to provide an innovative weaving device and weaving method of a gradient structure woven fabric to overcome the drawbacks of the prior art.
