Abstract

Incorporation of clay as filler for epoxy has received considerable attention to improve the performance of the composites. In this study, clay-polymer composites for the roof tiles application were prepared by hand lay-up process. The effect of clay addition on the morphological and mechanical properties of the clay-polymer composites were investigated. The mechanical properties of the as-prepared composite were evaluated by the impact test, flexural test and tensile test. The results revealed that the impact strength, flexural strength and tensile strength of the composites were increased with the clay addition into the epoxy matrix. However, at higher amount of clay addition, 5 wt% of clay, reduction of mechanical properties was observed which is might due to the formation agglomerations of the clay particles and poor dispersion of clay in the epoxy resin. The SEM result shows that at 1 wt% of clay addition, the clay particles and fiber was well dispersed and stick together which is may cause the increment of the mechanical properties. Meanwhile at 3 wt% and 5 wt% of clay addition, the micro voids were formed and the huge lump of clay agglomerations were absence in the clay-polymer composites which lead to the reduction of the mechanical properties
