Figure 2: EDX of clamshell powder. To investigate the effect of clamshell filler incorporation, two categories of composite were prepared: bamboo composite without filler and with filler. The unfilled base composite (without filler) was prepared with bamboo-epoxy in a 35-65 wt.% ratio. Hybrid bamboo-epoxy composites were prepared by maintaining a 35 wt% bamboo fiber content. The clamshell filler was incorporated into the epoxy matrix at different loadings, with the epoxy proportion adjusted accordingly. Tab. 2 provides the details of all the composite compositions. For fabricating these bamboo composite panels, hand lay-up process followed by the compression molding technique is used. Post-curing, the composite panels were demolded, and specimens were prepared for further testing in accordance with ASTM standards. Fig. 3 illustrates the steps involved in the fabrication of bamboo composites.
