Adopting carbon aerogel and phenolic resin to fabricate polymer composite is the aim of this study.Carbon aerogel, a spongy porosity carbon material, gathered by a fixed amount of nano-particles possesses particular physical property.Different proportions of carbon aerogels are added into phenolic resin to fabricate resin solution containing carbon aerogel.Ultrasonication and fiber laminate were adopted to make prepreg, and hot-press molding method was finally used to make a nano-composite containing carbon aerogels.Furthermore, the mechanical and thermal properties tests and morphology were finally conducted.
