Abstract

This paper has demonstrated the potential of UV curing technology when applied to glass fibre reinforced composites. Two manufacturing routes for making panels have been compared: manufacturing each element by its side and their subsequent bonding, and the direct integration of the profiles in the UV curing of the skins. The results of interlaminar tests show that the strength of the prepreg/profile bond is comparable to that of the prepreg/prepreg bond. Consequently, the prototypes obtained with both strategies show similar mechanical performance, both in stiffness and flexural strength. Finally, the low-temperature UV curing of the skin allows the use of water-soluble cores manufactured by 3D printing, which facilitates lamination and compaction operations.
