METHOD OF PREPARING THE COMPOSITE PROPELLERS CONTAINING SELF HEALING MATERIAL AND COMPOSITE PROPELLERS MADE BY THE METHOD

摘要

The present invention comprises the steps of preparing a mold; Forming a preform using the mold; And it relates to a composite propeller manufacturing method comprising the step of injecting a matrix resin, self-healing material and pigment in the preform. According to the present invention, it is possible to realize the weight reduction by replacing the existing Ni-Al Bronze propeller with a composite material, and even if fatigue failure progresses, destruction is prevented by the self-healing mechanism, and the cracked part of the damaged part can be visually confirmed. It has an effect.
