HAND LAY UP
The manual lamination or hand lay up is the most simple molding technique adopted for the production of articles made of composite material; very widespread in the environment as well as for the easy execution, also for the reduced cost of the devices necessary for the use. This system consists of applying layers of resin and fabrics, interspersed by the removal of air bubbles, until reaching the desired thickness. To get a correct fabric-resin ratio, and thus a better mechanical resistance of the manufactured article, it is recommended to apply a peelply skin as the last layer, to be eliminated after hardening. The process requires that the surfaces are clean, because if not these, could affect the final appearance and the structural behavior of the product.
