済む。[Effects of the Invention] Since the present invention is constructed as described above, it is possible to produce an FRP that exhibits decorative parts in irregularly shaped parts such as uneven parts and curved parts.
Molded products can be manufactured reliably without causing breakage or cracks. In addition, the nonwoven fabric that is the source of the decoration has heat resistance and strength resistance (tensile strength 15/5cm) that corresponds to the pressing conditions.
As mentioned above, since it has a tear strength of 1.5 kg or more), the desired decoration can be beautifully expressed without any distortion or deviation. Moreover, since a prepreg sheet is used, the material cost is also low.
