PROPELLER BLADE WITH COMPOSITE MATERIAL TO IMPROVE A CAVITATION RESISTANCE

摘要

PURPOSE: A composite material propeller blade with excellent cavitation resistance is provided to minimize the damage of cavitation by forming a blade tip part with flexible composite materials and to maintain the stiffness of a root part of a blade for a ship with metal materials. CONSTITUTION: A composite material propeller blade is formed by nonferrous metal materials. Adhesive is coated on adhering parts(4) in both sides of a root part of a blade. Multiple flexible composite material fiber layers are laminated on both sides of the root part of the blade to form the tip part of the blade in a single body.
