What are the four main fiber preparation methods in fiber composites?

The molding processes of fiber composite materials mainly include: hand paste molding, compression molding, spray molding, winding molding, pultrusion molding, vacuum introduction molding, RTM molding, autoclave molding and so on.

There are four main methods to prepare fibers in fiber composites: 1. Melt stretching method II. Thermal decomposition method 3. Drawing method 4. Vapor deposition method.

Among the many molding processes of fiber composite materials, do you know which production process can reach 80% fiber content? Hao Bo composite materials are analyzed for you: the fiber content of hand-pasting process is generally 30-40%, that of vacuum-introducing process is generally 60-70%, and that of RTM process is generally 50-60%. The pultrusion process uses direct yarn (also plied yarn), and the prepreg will be subjected to an extrusion force after entering the die, and the fiber content can reach 80%.
