There was no practical composite material having a soft plastic layer directly laminated thereon. That is, even if a soft plastic is applied directly on the FRP to cure it, there is no suitable curing agent, the curing takes more than half a day, and the productivity is extremely poor. Therefore, the soft plastic layer is directly laminated on the FRP. There was no practical composite material. Since soft plastics such as soft vinyl chloride resin and FRP are poor in adhesiveness, there was a case where FRP was subjected to a primer treatment and then adhered to each other with an adhesive. However, there is a possibility that those bonded with an adhesive may peel off if there is poor adhesion.

Conventionally commonly used thermosetting resins such as polyester resins, epoxy resins, phenol resins and furan resins can be used. Of these, polyester resins are preferable because they can be easily cured even at room temperature, do not generate gas as a by-product during curing, and do not need to be pressurized during molding. Although glass fiber is generally used as the reinforcing material, various fibers such as carbon fiber, aramid fiber, and acrylic can be used.

The FRP layer and the soft plastic layer are chemically bonded and both layers are firmly bonded. It is considered that the polymers of both layers are crosslinked and cured by the vinyl-based monomer contained in both layers to be bonded.

る。When urethane acrylate is used as the soft plastic resin, cobalt naphthenate, N, N dimethyl paratoluidine and the like are preferable as the curing accelerator. The addition amount is about 1 to 2.5% by volume of cobalt naphthenate and about 0.3 to 1% by volume of N, N dimethylparatoluidine with respect to urethane acrylate. If the added amount is too small, it takes a long time to cure. If the amount is too large, the curing will proceed too much, resulting in brittleness. The combined use of cobalt naphthenate and N, N dimethylparatoluidine is preferable because the curing acceleration effect becomes large. In order to adjust the viscosity and make it easy to handle, an appropriate amount of styrene monomer, for example, 5 to 10% by volume is used.
You may add about. It is also possible to add a pigment to obtain a desired color. It is also possible to add an anti-sagging agent to facilitate the molding work on the inclined surface, or to add an antifoaming agent to prevent the generation of bubbles during stirring.

ラスチックの軟質性が損なわれる。The vinyl-based monomer contained in the soft plastic resin acts as a cross-linking agent, and the styrene monomer is excellent in reactivity and cost. The content is not particularly limited, but is about 5 to 40% by volume with respect to the soft plastic resin. If the content is too small, the crosslinking effect cannot be sufficiently exhibited, and if it is too large, the softness of the soft plastic is impaired.

きない。When the surface of the soft plastic resin is cured while being exposed to the air during curing, the inside of the surface of the soft plastic resin is cured in an uncured state. The inside is substantially cured (close to the end of the curing reaction but the curing reaction is still in progress), and only the surface portion forms the FRP layer on the uncured soft plastic layer. Even if the internal curing is completed, the surface portion in contact with air remains in an uncured state, but even if an FRP layer is formed on the soft plastic layer in this state, the bonding cannot be performed well. On the other hand, when curing the soft plastic resin, the surface portion is also cured if the surface portion is cured in a state where the air is blocked. However, the FRP layer is formed on the soft plastic layer in which the surface portion is completely cured. Even if it tries, the soft plastic layer and the FRP layer cannot be joined well.

Any of the hand lay-up methods may be used, in which the reinforcing fiber base material is impregnated with and used for defoaming and molding. F used here
The same vinyl monomer as that contained in the soft plastic resin, preferably a styrene monomer, is contained in the RP resin. Specifically, as the FRP resin containing a vinyl-based monomer, a styrene monomer-containing polyester resin or the like is preferable. As a vinyl-based monomer for crosslinking polyester, a styrene monomer is excellent in terms of reactivity and price. The styrene monomer content is about 20 to 40% by volume based on the polyester resin. Methyl ethyl ketone peroxide is used as a room temperature curing catalyst for a polyester resin, and cobalt naphthenate is used as an accelerator as in the past. The curing time is about 30 to 60 minutes, and it can be cured at room temperature.

った。 Comparative Example 1 Styrene monomer 26 containing 5% paraffin in a soft resin
The soft resin was cured in the same manner as in Example 1 except that 0 cc was further added. As the curing progressed, the paraffin became a film and floated on the surface of the soft resin, and the surface portion was cured in a state where air was blocked, and the surface portion was also cured.
When the FRP layer was formed on the soft plastic layer whose surface portion was completely cured in this way by the same operation as described above, the soft plastic layer and the FRP layer could not be joined.
