Aerosil R812 (8 nm) andAerosil R972 (12 nm) were utilized at 3% and 5% w/w ller to resin ratio and the resin/ ller mixture was combined with12-ply carbon fabric to get 1515 cm samples. Samples were molded under a hot press and for each sample 50 testsamples obtained by cutting them with a water jet. The obtained samples were characterized by TG, FTIR, and SEM.The effect of water absorption was evaluated by measuring percentage water absorption and exural strength of samplesover 9 months. The results revealed that ller addition lowers the damage created by distilled water a considerableamount and addition of hydrophobic llers to epoxy matrix composites can be especially bene cial for applicationswhere long-term water exposure is desired.eninfo:eu-repo/semantics/openAccessArticle402321331256071
