[0002] Bars are common structural forms in the field of composite materials. For composite material bars with longer dimensions, common forming processes include pultrusion process, autoclave process, and vacuum infusion process. For composite material long bars used in satellite trusses, if the pultrusion process or vacuum infusion process is adopted, the mechanical properties and resin content are difficult to meet the index requirements, while the cost of the autoclave process is relatively high. The composite material bars used in satellite trusses are generally formed by the compression molding process.
