Problems solved by technology

[0003] 1) The fiber is in a free state during molding, and the performance of the tubular member is poor after molding;
[0004] 2) The transportation cost of prefabricated tubular components is expensive, the tubular components are hollow, the tubular components are large in size, and the effective loading quantity is small;
[0005] 3) Prefabricated tubular components require on-site professional tools or manual cutting, complex installation, heavy workload, and a lot of manpower and material resources;
[0006] 4) When prefabricated tubular components are cut on site, the waste of excess material is serious

Abstract

The invention discloses a rapid molding method of a pre-stressed tubular member. Reeling is carried out before molding in order to save the space and the amount, the onsite molding method is simple, and solves the problems of high transportation cost and difficult transportation of tubular members especially large tubular members in the market, and a reinforcing material (such as a continuous glass fiber) has certain pre-stress, is positioned in a pre-tensioning state, has extremely good mechanical, physical and chemical performances. The molding method has the advantages of rapid and simple molding, onsite molding as needed, material waste avoiding, great cost reduction and wide market prospect.

Description

technical field [0001] The invention relates to a preparation method of a tubular component, in particular to a rapid prototyping method of a prestressed tubular component. Background technique [0002] Among the existing tubular members (including composite tubular members), most of them are tubular members with pre-defined dimensions. When applied, they need to be transported to the site of use and then cut into corresponding lengths with special tools. Composite tubular members are often wound. And other craft production, manufacture needs professional specialized equipment, and cost is high. Its disadvantages are: [0003] 1) The fiber is in a free state during molding, and the performance of the tubular member is poor after molding; [0004] 2) The transportation cost of prefabricated tubular components is expensive, the tubular components are hollow, the tubular components are large in size, and the effective loading quantity is small; [0005] 3) Prefabricated tubu...
