Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] According to typical embodiments of the present invention, such as figure 1 As shown, the guide sleeve with the outer layer of wire material includes a guide sleeve body 1 and a fiber layer 2 arranged on the guide sleeve body 1 . Applying the technical solution of the present invention, the guide sleeve is composed of the guide sleeve body and the fiber layer arranged on the guide sleeve body. Due to the existence of the fiber layer, the outer layer of the guide sleeve is no longer a natural surface, and the uneven fiber layer makes the reinforcement The connection position between the fiber and the guide sleeve is fixed, and it is not easy to slide, thereby ensuring the stability of the ...

The invention discloses a guide sleeve with an outer wire layer. The guide sleeve comprises a guide sleeve main body and fiber layers arranged on the guide sleeve main body. According to the technical scheme of the invention, the guide sleeve with the outer wire layer consists of the guide sleeve main body and the fiber layers arranged on the guide sleeve main body. Due to the presence of the fiber layers, an outer layer of the guide sleeve is no longer a natural surface, and reinforcing fibers are fixed with the guide sleeve at a connection position by the uneven fiber layers, so as not easy to slide, thereby ensuring the stability of a prefabricated structure, and enhancing the bite force between the guide sleeve and a reinforcing fiber bundle and a matrix simultaneously. Furthermore, the method of increasing the guide sleeve surface friction is different from the means that the guide sleeve is processed with a chimeric groove to lock the fibres with the guide sleeve in prior art, thereby avoiding the machining cost increase and problems such as easy fracture and the like resulted from stress concentration at a groove.
Description
technical field [0001] The invention relates to the field of guide sleeve manufacturing, in particular to a guide sleeve with a wire outer layer. Background technique [0002] With the gradual scarcity of resources such as oil and coal mines in recent years, the production and transportation costs of material manufacturing have greatly increased. Therefore, many researchers are now focusing on the lightweight technology of materials, especially in aerospace, automotive and other fields. On the basis of ensuring the performance requirements of the material, reducing the weight of the material used can greatly reduce the energy consumption during production and transportation. Composite materials have been more and more widely used in aerospace, automobile, artificial biological tissue manufacturing and other industries in recent years due to their performance advantages such as small specific gravity, high modulus, high strength, fatigue resistance, and corrosion resistance. ...
