Group: Forum Members Posts: 2, Visits: 193	I'm having trouble with this partly double sided infusion. This was the most recent try. Layup: (Mould Side) 200 g/m² Glass Twill Weave 300 g/m² Carbon Biaxial +-45° 300 g/m² Glass Biaxial +-45° 400 g/m² Glass Unidirectional 0° 10 mm Gurit Corecell M80 Foam, Perforation Grid 2mm / 20 mm 300 g/m² Glass Biaxial +-45° 200 g/m² Carbon Unidirectional 0° 200 g/m² Carbon Unidirectional 0° 300 g/m² Carbon Biaxial +-45° 160 g/m² Carbon Twill Weave 78 g/m² Glass Twill Weave MTI hose on left side, feed line on the right. Can't measure absolute pressure, but relative pressure was -0,93 Bar. Resin was degassed until no more bubbles were visible. Didn't turn out well. It looks like the flow front on the A side was significantly slower than on top, which resulted in complete dry spots. Do you have any advice on what to do differently next time? I already tried infusing from back to front instead of left to right, which turned out better. Attachments IMG_20150104_170946-1.jpg (677 views, 177.00 KB) Edited 10 Years Ago by gnidnu
