Despite, outstanding structural and adhesion property of epoxy system,lack of toughening trait,makes some doubts. We are here to diminish the doubts of using this god’s gift;EPOXY. So,we add butyl acrylate styrene,a economical useful copolymer.what will happen? We’ll see,acrylate groups love epoxy and they soar to their angel,styrenes are not willingly satisfied but they are attached to acrylates,they have to accompany;but trying to stand out of pitch. Thus;a globe will be made by butyl-acrylate-styrene;not allowing the cracks to grow and intrinsically converting epoxy to a more kind fella. But also we adore mechanical properties,they are not good as before.so we add nanoparticles,they bear the load,if good attached to epoxy. We chose Fe2O3 nanoparticles to handle the duty.they worked and we made a sample that has wee higher toughening and higher mechanical traits.
