Conventionally, glass fibers, carbon fibers, aromatic polyamide fibers, boron fibers, alumina fibers, silicone carbide fibers, etc. have been used as reinforcing materials, and as matrices, materials such as epoxy resins, unsaturated polyester resins, aryl resins, polyimide resins, and phenolic resins have been used. Prepreg impregnated with a thermosetting resin is seen as promising as a material for crafts for aircraft and vehicles, or as a material for sports and leisure such as golf shafts, fishing rods, and racket frames, and its use is being actively developed.

On the other hand, in order to fully utilize the characteristics of reinforcing fibers in composite materials, there is a strong demand for increasing the fiber content in prepregs, that is, developing prepregs containing low levels of resin. However, there are several problems when attempting to mold such a low resin content prepreg. It is extremely difficult to finish the product to the specified thickness, and if there is even a small amount of resin, the thickness of the molded product will be uneven.Also, when designing the molded product, it is difficult to mold it to the design according to the dimensions. According to the regulations, it was necessary to modify the molding. When using a material with a large amount of resin, an auxiliary receptacle material is required to remove excess resin, and the time and effort required during molding increases.

There is a strong demand for the development of prepregs with less resin in VC in order to eliminate the troublesomeness of dirt, and various companies are proceeding with the development of prepregs with low resin content. However, if matrix resin-impregnated prepreg is placed in conditions where the resin flows even slightly, the matrix resin tends to move toward the release paper side of the prepreg, and the resin content on the open surface side of the prepreg tends to decrease. 7. The surface viscosity increases, which tends to cause a decrease in the tackiness of the prepreg surface. This tendency is remarkable in high-performance prepregs with low resin content compared to conventional prepregs with matrix resin coalescence of 3S% or less.
Such prepregs with low surface tackiness have poor molding properties, and may cause inconveniences such as the occurrence of interlayer phase iA voids or the occurrence of delamination phenomena when using composite phase molded products made using this prepreg. From the viewpoint of increasing the chances of occurrence of leprosy, there has been a strong desire for the appearance of a prepreg with improved viscosity properties as shown in Table m1. In particular, in the case of G-16, the above-mentioned drawbacks were strongly manifested in the case of G-16, in which the above-mentioned prepregs were pasted together on the surfaces, and an ultra-thin glass fiber prepreg was pasted on the surfaces.
