Problem encountered with vacuum infusion (also named SCRIMP method): Vacuum infusion method consists to inject resin in a closed structure composed of an open mold, topped with a hermetic cover which contains glass fiber or other and all together connected to a vacuum installation. Before infusing the fiber with resin, firstly we have to be sure everything under vacuum pressure (almost between -0.5 et -0.9 Bar) is leak tight. If there are leaks in the plastic cover, then the resin dispersion will not be uniform in the glass fiber which will result in imperfections in the finished product....
