The invention discloses a preparation method of a high-rigidity
composite material transmission shaft, belongs to the technical field of
carbon fiber composite materials, and particularly relates to a composite transmission shaft with functional
grapheme modified resin as a base body and adopting different grades of carbon
fiber for winding and a preparation method of the
composite material transmission shaft. High-strength
fiber is adopted for hoop winding, high-modulus
fiber is adopted for spiral winding, the strength and rigidity in all directions of the
composite material are adjusted and controlled, the performance advantages of the various kinds of fiber are brought into full play, the
cost performance is high, and the integral rigidity of the composite material is improved. In addition, by the adoption of the functional
grapheme modified resin
system, interface combination of the resin and carbon fiber is improved, and the integral rigidity of the composite material is further improved. The composite material transmission shaft prepared through the preparation method has the advantages of being high in rigidity, excellent in torsional property, high in production efficiency, low in cost and the like, and has a wide application prospect in the fields of automobile industry, transmission machines and the like.
