| abstract |
The present invention relates to a prepreg, a preparation method thereof, and a fiber reinforced composite material prepared therefrom. The preparation method of the prepreg enables the provision of a prepreg which comprises an aramid fiber substrate having improved wetting property with respect to a resin, can show an increased thickness reduction ratio upon prepreg molding, has an appropriate resin content, and is suitable for molding by a de-autoclave molding method. In addition, the prepreg shows a thin thickness and a high resin content even by a de-autoclave molding method, and enables the provision of a fiber reinforced composite material exhibiting high strength and a low moisture absorption rate. |
