In particular, composite materials using charcoal fibers, aromatic polyamides, etc. as reinforcing fibers are often used for structural shrines of aircraft etc., taking advantage of their high specific strength and specific rigidity. If these composite materials for aircraft have heat resistance and high elongation in addition to the above properties, the range of application of composite materials will not be limited to secondary structural members, but will be widely used in primary structural members. It has also become possible to apply this technology to aircraft, making rapid progress in reducing the weight of aircraft chains, bringing great advantages in terms of energy savings and safety.

The carbon fiber used as the reinforcing fiber in this composite material has conventionally had a low elongation of about 1.0 to 1.3%, but recently it has become highly elongated with an elongation of 1.5% or more. High-strength carbon fibers are being developed, and it was hoped that they could provide high-strength composite materials. However, there is no matrix resin that is one component of the composite material that has both heat resistance and high elongation, and therefore the properties of high elongation carbon fibers have not been fully utilized.

That is, in general, matrix resins with excellent heat resistance have low elongation, and conversely, those with high elongation have poor heat resistance, and it has not been possible to satisfy both of these requirements at the same time.

When the amount of [E] acid component dicyandiamide and its curing accelerator is less than 0.2 to 5.0 parts by weight, the elongation of the resin after curing decreases and a composite material with high elongation is obtained. If the amount exceeds 25 parts by weight, the heat resistance of the composite material will decrease. When component (D) is less than 15 parts by weight, the heat resistance of the composite material decreases, and when it exceeds 50 parts by weight, the water resistance of the composite material decreases. When each of component (E), dicyandiamide and curing accelerator, is less than 0.2 parts by weight, precure becomes necessary, and when it exceeds 5.0 parts by weight, the heat resistance of the composite material decreases.
