OUT OF DIE ULTRAVIOLET PULTRUSION PROCESS SET-UP: LIMITATIONS OF PHOTO-DIFFERENTIAL SCANNING CALORIMETRY ANALYSIS

Iosu Tena (University of Mondragon) Iván Sáenz Domínguez (Mondragon Unibertsitatea) Modesto Mateos (Mondragon Unibertsitatea) Mariasun Sarrionandia (Mondragon Unibertsitatea) Jon Aurrekoetxea (Mondragon Unibertsitatea)

 

The aim of this study is to analyse the limitations of the traditional photo-differential scanning calorimetry (photo-DSC) analysis compared to electric monitoring (DC sensor) in the out of die ultraviolet (UV) pultrusion process set-up.
