The blade is 37.5 metres long and weighs around 6 metric tons. It was made with glass fibre fabrics from Chongqing Polycomp International Corp. (CPIC) and processed with a polyurethane online infusion machine from HÃœBERS, a specialist in process engineering, at the Shanghai FRP Research Institute. Note de contenu : - Influsion and impregnation without voids - Optimized cost efficiency - Successful prototyping - Faster infusion and curing - Larger rotor blades with optimized design - PU system technology with high output rate FIGURES : 1. As demonstrated by measuring the lap shear-strength, the PU resin's adhesion is significantly better than that of epoxy resin. Even the adhesion of the EP infusion resin to the PU substrate is superior to that on the EP substrate - 2. Regardless of the thickness, the epoxy adhesive shows better adhesion to the PU substrate than to the EP substrate En ligne : https://drive.google.com/file/d/15ICThDd92U7OwtVWGVUydLieDpbiUtBK/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28171 [article]
