filler has a negative effect on the impact strength of composites. The lowest impact strength of 52 J/m was recorded for 9 wt.% of CS filler. Including CS filler increased the hardness, which may have reduced the fibre-matrix interface's ability to absorb less energy under impact load, leading to the observed reduction in impact strength. Similar results were recorded by H. Jena et al. [39] when they added clamshell filler to jute epoxy composite, impact strength was decreased. They explained this decrease by pointing to the addition of filler to the neat polymer, which enhanced its hardness and decreased its crystallinity.
