作業能率が悪い専の問題があった。Figures 2 and 3 are schematic diagrams of the main parts of the autoclave method. In the method shown in Figure 2, the sheet (9) is coated on the molded object (8) and then sealed, the inside is depressurized, and the outside is applied. It was molded by heating under pressure. In this method, one sheet (9) is used to cover the top and all sides of the object to be formed (8), so sealing at some corners tends to be incomplete, sheet rupture is inevitable, and only - times are used. There were problems such as not being able to do so. In addition, in the method shown in FIG. 3, the object to be molded (14) is surrounded by a frame υ, the upper part is covered with a sheet, and heated under reduced pressure inside and pressurized outside. In this method, the frame (2) needs to be made of a thick and heavy plate to have an extremely strong strength, which places a heavy burden on the operator.
There was a problem with a specialist who had poor work efficiency.
