Scholarcy highlights

  • The lack of knowledge of the behaviour of an epoxy polymer matrix has become a challenging issue for the design of a serviceable, durable and economic matrix
  • This study investigated the effect of the resin-to-filler ratio on the thermal, physical, mechanical and durability properties of polymer matrices composed with epoxy resin and light weight filler materials
  • This ratio was considered the experimental variable on which the properties of a polymer matrix are primarily dependent
  • The control mix was composed of 100% resin to which an amount of filler material of up to 60% of its volume was added in increment of 10%
  • If durability was the priority, it was suggested that either a 30% or 50% filler mix be used depending on the relative importance of the mechanical properties and cost factors
