Abstract

The invention discloses a method for manufacturing chain rigging with carbon fiber composite material, which belongs to the technical field of traction rigging. The purpose is to provide a method for manufacturing chain slings with carbon fiber composite materials with light weight, high strength, not easy to oxidize, good corrosion resistance to acid, alkali, salt spray, etc., and good fatigue resistance. The method includes the following steps: Step 1: a chain one-ring forming plan: including forming; pressing; curing; a chain second-ring forming plan: including forming; pressing; curing. The use of carbon fiber composite materials to make chain slings can solve the problems of poor continuous fatigue resistance encountered by original steel cable chains. The invention is especially suitable for the fields of shipboard helicopters, fighter jets, warships, civil ships, offshore oil exploitation and the like.

Description

technical field [0001] The invention belongs to the technical field of traction slings, and in particular relates to a method for manufacturing chain slings with carbon fiber composite materials. Background technique [0002] The cable chains used in the market are all made of metal, and metal materials exist: [0003] 1. High density and heavy weight (overweight mooring cables of carrier-based aircraft affect the combat capability of individual soldiers; overweight anchor chains of warships and civilian ships increase dynamic load; overweight mooring chains of offshore oil exploitation affect platform dynamic balance; The anchor chain of the deep-sea buoy is too heavy to affect the use length: the limit is 800 meters). [0004] 2 Easy to oxidize. Poor anti-corrosion ability (especially the harsh environment of the offshore anchor chain, which requires high tensile strength, anti-corrosion ability and service length of the cable chain, and the traditional steel anchor chain...
