Definitions
- the present invention relates to an epoxy resin composition that provides a prepreg having excellent tackiness and drapability, a prepreg obtained therefrom, and a fiber-reinforced composite material.
- Composite materials consisting of reinforced fibers and matrix resin are lightweight and have excellent mechanical properties, so they are used for sports applications such as golf shafts, fishing rods, tennis rackets, aerospace applications, and general industrial applications. Widely used for sports applications such as golf shafts, fishing rods, tennis rackets, aerospace applications, and general industrial applications. Widely used for sports applications such as golf shafts, fishing rods, tennis rackets, aerospace applications, and general industrial applications. Widely used for
- a method using a prepreg which is a sheet-like intermediate substrate in which matrix resin is impregnated with carbon fiber, is widely used. ing. In this method, a molded product is obtained by laminating a plurality of pre-preda and heating the laminate.
- thermosetting resin As the matrix resin used for the pre-prepared material, thermosetting resin, and in most cases, thermosetting resin used together with the thermoplastic resin, among which epoxy resin is used. Xylene resin is mainly used.
- the prepregs that have been pressed down repeatedly in the prepreg lamination process will immediately peel off, which will hinder the lamination work. In such a case, it is necessary to raise the working environment temperature until a proper tackiness is obtained.
- the tackiness of the pre-preda is too large, it will stick due to the weight of the pre-preda, for example, if it is accidentally overlaid, making it difficult to peel off and correct it later. I will.
- the drape of the prepreg is poor, the prepreg is hard and the laminating operation is remarkably reduced, and the laminated prepreg is accurately formed on the curved surface of the mold and the shape of the mandrel; Wrinkles and broken reinforcing fibers cause defects in the molded product. Even in such a case, it is difficult to find a balance between the force and the tackiness that require a high working environment temperature, and these are very serious problems in the molding operation. .
- the tackiness and drapability of the pre-preda are mainly governed by the viscoelasticity of the matrix resin, and the viscoelasticity of the dioxy resin is largely temperature-dependent. Environment 3 If the temperature fluctuates due to the season, etc., the stickiness and drape will change, and in some cases the work may become impossible.
- the resin flow is the flow of resin when the il degree rises during the molding process.
- the resin flute is large, the resin will flow out, and the resin fraction and thickness of the product will tend to deviate from the design values.
- the resin flow is large, fine bubbles in the resin aggregate during molding, causing voids in the molded product and reducing the strength of the molded product.
- Pre-preg made of high modulus fiber, especially high modulus carbon fiber, has been demanded in the market especially for years, since it is easy to design lightweight. -However, if high modulus carbon fiber is used as the reinforcing fiber, the drapability of the prepreg will be reduced, and Tends to exhibit a property of lowering tackiness because the resin on the prepreg surface sinks with the passage of time; therefore, using a conventional resin would result in lower tackiness and lower tackiness.

- the resistance and elastic modulus of the cured product of the resin composition decrease, and Sufficient properties such as heat resistance and physical properties such as 0 ° compression strength of a fiber-reinforced composite material obtained by curing a prepreg using a composition as a matrix resin have not been obtained.
- thermoplastic resin and an epoxy resin composition are present as completely different phases. If the thermoplastic resin takes the form of a film and covers the entire surface, the surface loses tackiness. When particles of a thermoplastic resin are used, the epoxy resin composition is sufficiently exposed on the surface so that the tackiness is not lost, but the tackiness when the particles are not used is improved. However, it is only possible to maintain the roughness, and further improvement in tackiness cannot be expected. In addition, none of them have been obtained that satisfy heat resistance, adhesiveness, impact resistance and the strength of the composite material as a whole.
- the demand for prepregs with a high fiber content is increasing as the weight of golf shafts and fishing rods is reduced.
- the higher the reinforced fiber content the more the prepregs are distributed on the prepreg surface.
- Low tackiness due to reduced amount of resin It becomes bad.
- a high-viscosity resin containing the above-mentioned polymer compound is used to improve the tackiness, it is not easy to impregnate the reinforcing fiber bundle with the reinforcing fiber bundle when the content of reinforcing fibers is originally high.
- high viscosity makes impregnation even more difficult, and the quality of the prepreg, such as smoothness, deteriorates.
