The effects of particle size variation on compressive strength, effective elastic modulus, and modulus of toughness were investigated. An upper and a lower bound were estimated for the elastic modulus of particles in EP/epoxy foams. EP/epoxy foams showed Reuss-like behaviour similar to metals but atypical of non-plastic materials. In addition, results illustrated the significant contribution of the expanded perlite particles in the effective elastic modulus of the foams. Micro-structure of expanded perlite particles was examined and related to their macroscopic properties via two geometrical relationships. Post-test microscopic observations coupled with macroscopic observations taken during the test were used to understand the effect of particle size on the behaviour of the foams under compressive load. Observations revealed the presence of three different failure modes for all foams regardless of their particle size and density; however, the strain to activate each mode was different for each foam type.]]> Tue 04 Dec 2018 15:00:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28964 Thu 26 Jul 2018 16:53:38 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9392 Sat 24 Mar 2018 08:39:35 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26798 Sat 24 Mar 2018 07:36:26 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29501 Sat 24 Mar 2018 07:29:45 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26919 Sat 24 Mar 2018 07:23:34 AEDT ]]>
