できる。The glass chop layer used in the present invention is made of alkali-free glass, and the chop length, filament diameter, number of convergence, etc. are not particularly limited, and those commonly used can be used as they are. It also corresponds to the required thickness of the molded product and is not limited. The saturated polyester nonwoven fabric includes general nonwoven fabrics such as nonwoven fabrics, mats, and papers made of saturated polyester resin fibers, and there are no particular limitations on the filament diameter, denier, thickness, etc. of the fibers. The unsaturated polyester resin includes not only the unsaturated polyester resin alone but also its modified products. glass chop layer,
The weight distribution of the saturated polyester nonwoven fabric and unsaturated polyester resin is 10 to 40% by weight for the glass chop layer (hereinafter simply referred to as %), 2 to 15% for the saturated polyester nonwoven fabric,
Preferably, the unsaturated polyester resin accounts for 50 to 80%. That is, if the glass chop layer is less than 10%, it is difficult to obtain high strength, and if it exceeds 40%, the weight tends to be high. This is because if the content of the saturated polyester nonwoven fabric is less than 2%, it is difficult to make it lightweight, and if it exceeds 15%, it is difficult to make it high strength. Inorganic powder fillers such as calcium carbonate, clay, silica, talc, and aluminum hydroxide can be added to the unsaturated polyester resin as needed. As for the crosslinking agent, mold release agent, coloring agent, surfactant, etc., commonly used ones can be used as they are.

上でよく望ましいことである。In this way, the above-mentioned base material is impregnated with an unsaturated polyester resin to obtain a sheet-like unsaturated polyester resin molding material, but it is preferable to use a resin that has been defoamed under reduced pressure,
Impregnation under reduced pressure is often desirable to eliminate air bubbles in the molding material.
