Lamination molding process is an open molding method for composite materials. This process develops earlier and is more mature. It is characterized by high product quality, stable process and low investment in mold. The disadvantage is that it can only produce flat plates and songs. Board and so on.
However, compared with the extruded sheet, the laminated sheet still has the advantage that the extruded sheet is irreplaceable: the laminated sheet can be produced in a thickness of 2 to 50 mm, and the domestic extruded sheet is between 2 and 20 mm in thickness, 20 Plates above mm can only be produced by lamination. Therefore, although the lamination production process is long and the energy consumption is large, it is still an important production method.
