liquid beam which reaches a velocity of 2.5 times the speed of sound, creating a pressure on the fabric which is higher than the compression resistance of the material and resulting in a net cut. Both these methods share a common disadvantage which needs to be considered before choosing the cutting methods: the beams create high-temperature areas along the cut axes, in which the physical characteristics of the material can be altered significantly. During the cutting process, a fundamental parameter to be considered is the nesting layout, which is the arrangement of the different shapes to be cut from the fabric in order to reduce the scraps. The patterns are generally created digitally and, when possible, given to a CNC machine or, otherwise, replicated by hand. Lamination Lamination of the fabrics is the second stage of the Lay-Up process. It is the procedure of overlapping all the layers in the correct order and with the correct orientation. In the case of Wet Lay-Up, the preparation of the resin is included in this operation, as the fabrics are not already impregnated. Lamination is usually performed in a clean-room to avoid particle inclusions within the layers, which would interfere with the characteristics of the final product. The most important tool is the mould, which can be male or female depending on the application. It can be made of different materials, depending on the shrinkage and the thermal expansion coefficient of the composite material, the stiffness required, the surface finish needed, the draft angles and the bending angle. Furthermore, the mould must be stable at the lamination temperature, bear the operative pressure, be resistant to wear, be compatible with the other tools used, be resistant to washing solvents and it must be easy to apply release agents.The first step of lamination is to apply a release agent on the mould, fundamental to avoid adhesion between the resin and the mould itself. If needed for surface finish, a layer of peel-ply may be added. Peel-plies are nylon films used to obtain a specific roughness of the surface on which they are applied, to protect them during storage and to trap volatile particles during polymerization. Then, all the fabric layers are overlapped following the instructions on the ply-book, which contains a list of all the operations to be performed during this process. Usually, intermediate compacting is performed every 4 or 5 layers, in order to
