A method for manufacturing a prestressed fiber reinforced wood-bamboo based pressure pipe for ships

Abstract

The application discloses a kind of preparation methods of prestressed fiber reinforced wood bamboo-based ship pressure pipeline, it is related to ship engineering and composite material manufacturing technical field, the method first wood bamboo board material is processed into the arc unit strip with mortise and tenon structure;Corrosion-resistant impermeable inner lining is prepared on core mold;Then arc unit strip is spliced and buckled outside inner lining along ring direction to form structure intermediate layer, and pipe blank is formed by ring direction pressurization and solidification;After surface treatment to pipe blank, high modulus continuous fiber is wound using variable tension and variable angle process to form prestressed reinforced outer layer;Finally, it is formed by secondary solidification, demolding and outer protective layer manufacturing.The application overcomes the defects of poor fire resistance, low pressure resistance and easy cracking of traditional biomass pipeline through rigid-flexible structure design and gradient tension winding process, and has excellent corrosion resistance, high specific strength and high modulus.
