Organic fiber yarn hot-melt carbon fiber mixed prosthesis composite material and preparation method

Abstract

The invention relates to a organic fiber yarn hot-melt carbon fiber mixed prosthesis composite material and a preparation method, and belongs to the technical field of prosthetic materials. Accordingto the organic fiber yarn hot-melt carbon fiber mixed prosthesis composite material and the preparation method, a method for processing a plate-shaped or rod-shaped semi-finished part for a prosthesisby using thermoplastic organic resin yarns and carbon fibers mixed three-dimensional weaving is utilized, and after the processing of a mixed woven prefabricated fabric is completed, the semi-finished part is placed in a specific mold for hot-melting treatment; and the organic yarns are subjected to specific high-temperature hot-melting and form a thermoplastic resin three-dimensional composite material with the carbon fiber three-dimensional prefabricated fabric, finally the composite material prosthesis of specific human body parts such as a thigh, a calf and an arm can be quickly preparedby special-shaped mold shaping, and meanwhile, the composite material prosthetic part has the adjustability for a specific shape and the physiological bending rate to effectively solve the problems such as deformation of the prosthetic part after long-term use.

Description

technical field [0001] The invention relates to the technical field of prosthesis materials, in particular to a method for preparing prosthetic parts by mixing thermoplastic organic resin yarns and carbon fibers. Background technique [0002] Medical rehabilitation engineering is an important comprehensive work in the medical field. It not only has a high level of requirements for medical engineering, but also is an intersection and integration of many disciplines such as biology, bionics, and materials science. Among them, prosthetics are Rehabilitation engineering is the earliest and fastest-growing field, and the development of prosthetics for upper or lower limbs is the earliest and fastest branch. Due to the complexity of the structure of human movement organs, the structure of the upper or lower limbs that conforms to the movement trajectory of the human body is also relatively complicated, and the curvature, organ shape and structural stability covered by this structu...

AI Technical Summary

Problems solved by technology

[0003] At present, the most common lightweight parts of the upper limbs, especially the lower limbs, are mainly composed of two-dimensional carbon fiber fabrics that are wound in a hoop or laminated. The composite prosthetics prepared in this way have many advantages such as light weight and high rigidity. However, due to the low interlayer strength of the laminated fabric structure, it also puts forward strict requirements for the rigidity and stability of the prosthesis.

In addition, the production of such prostheses is often prepared by impregnating carbon fiber composite fabrics with thermosetting resins, and the composite prostheses of this material cannot be subjected to secondary processing and constant shape or curvature due to the limitations of the characteristics of the resin matrix itself. Especially for children who are highly dependent on prostheses, the growth and changes of organs in the disabled parts will cause problems such as poor matching of the original prosthetic parts and discomfort. In summary, the traditional composite material structure There are many problems in the use performance, service life and use adjustment of prosthetic products. It is necessary to study a new composite material for prosthetic parts.
