Abstract

The invention discloses a preparation method of a continuous fiber enhanced thermoplastic resin composite paddle. The method comprises the following steps: preparing a continuous fiber enhanced thermoplastic resin unidirectional prepreg tape; clipping the unidirectional prepreg tape into two types of master slices along a 0-degree direction and a 90-degree direction, alternately stacking master slice groups formed by the two types of master slices in an orthometric manner, laying a core model in the middle of the master slice groups, transferring the master slice groups into a paddle die, performing hot press molding, and then performing machining trimming treatment, so as to obtain the paddle. The preparation method adopts hot-pressing technology, realizes one-step molding, is short in molding time, and ensures that product size is accurate and controllable; the formed paddle is excellent in mechanical property, anti-fatigue performance and corrosion-resistant performance, is light inweight and recyclable, and can be machined repeatedly.

Description

technical field [0001] The invention relates to the field of preparation of paddle blades, in particular to a paddle blade of continuous fiber reinforced thermoplastic resin composite material and a preparation method thereof. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, more and more modern people go to various sports venues to relax, and the development of modern competitive sports requires people to pay attention to scientific training, but also pay attention to sports Improvement and development of equipment. [0003] Rowing is one of the water sports, and it is a sport that relies on human paddling to make the boat move forward on the water. The paddle is an indispensable tool in rowing, and the paddle is the key component of the paddle. [0004] At present, the common paddle materials on the market include aluminum alloy, plastic, and thermosetting composite materials. Aluminum alloy bl...
