In my work, I am using MMT nanocaly and L12 epoxy resin. I got result that, adding nanocaly till 2 wt% , both tensile and flexural strength increased as compared to neat epoxy.. But at 4 wt% of nanocaly, the tensile strength slightly got increased but flexural strength got decreased as compare 2 wt% of nanocaly.
How can i conclude result and what might be reason for above result.
