Description: Abstract: In this paper we study the influence of the addition of small amounts of a ferrofluid to thermosetting polymers. Two resin systems were considered: one was based on a polyepoxy prepolymer/diamine hardener and the other on an unsturated polyester/styrene mixture. The curing behaviour of the modified systems was researched in terms of their time to gel and exhotermic peak temperatures. The fully cured systems were then characterized by scanning electronic microscopy (SEM) to typify the nanoparticle distribution in the polymer network. Dynamic mechanical thermal analysis was also performed to assess morphological and mechanical properties. Finally, their mechanical performance was determined by flexural quasi-static testing and Charpy impact testing.
