Automated cell manufacturing fiberglass composites starting from coils of all types of fiberglass fabrics, MAT, Combi and woven, based on ultraviolet (UV) curing technology. The cell consists of a prototype of manufacturing of preimpregnated UV, which has different processes, such as impregnation, dosing and precurado, and a second prototype of compaction and curing of the final composite, consisting of a compactor head driven by a robot. The cell is completed with the necessary equipment for the monitoring of the process, being able to measure forces, temperatures and degree of curing by means of the measurement of the dielectric properties of the material (DEA analysis). This cell also contemplates the characterization of the final composites by measuring porosity by ultrasound, thickness and fiber content by pyrolysis.
