In recent years, there has been a strong demand for higher performance of composite materials, especially improvements in heat resistance, water resistance, and impact resistance. These pre-reactants are being considered. As a result, although the rigidity of the resin increased and the heat resistance and water resistance of the composite material improved, there were problems with a decrease in elongation and a decrease in impact resistance.
