Abstract
, and 86.82 MPa respectively, the values are however lower than the unfilled. The hardness properties increased with increasing filler loadings with values from 23.8 HV - 32.7 HV for 10 wt% - 50 wt% respectively. The micrographs of the fractured impact samples confirmed the 10 wt% filler loading having the best properties with homogenous dispersion of the flamboyant pod particles (FPP) within the polyester resin. It can be concluded that lightweight composites with reasonable properties have been developed at 10 wt % loading which is suitable for non-load bearing and indoor applications in the automotive and building industries as partition tops, walls, and boards owing to their saturation in water after 30 days of immersion. The flamboyant pod material can be further explored for added values with tougher polymer matrices.
