Abstract

The invention discloses a method for preparing a continuous fiber-reinforced thermoplastic resin composite material boat oar blade, comprising: preparing a continuous fiber-reinforced thermoplastic resin unidirectional prepreg tape; Cut into two kinds of master pieces, and then stack the two kinds of master pieces alternately and orthogonally, place the core mold in the middle and transfer it to the blade mold, after hot pressing, and then trim the edges by machining Process to obtain the paddle blade. The invention discloses a method for preparing continuous fiber-reinforced thermoplastic resin composite paddle blades, which adopts a hot pressing process for one-time molding, with short molding time and accurate and controllable product size; the prepared paddle blades have mechanical properties and excellent fatigue resistance. Excellent performance, corrosion resistance, lightweight, recyclable and reprocessable.

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...
