1. Pultrusion technology
While in all cases pultrusion remains a continuous composite material transformation process capable of generating profiles of constant cross-section, there are several "technological filiations" within this large family.
The pultrusion of thermosetting resins and thermoplastics first of all, but also 2 or 3 derivative technologies: pullwinding, pullforming and pullpress.
1.1 Pultrusion of thermosetting resins
This is by far the most widespread family of composites today (over 99% of the market). Figure 1 shows the main stages in the transformation of the basic constituents of composites, which, in just a few meters, go from the state of fibers (in rolls) and resins (liquid) to that of a semi-finished/finished...
