Different carbon-based materials are used to tailor the properties of composites. However, there is a trend to replace the expensive carbon fillers with a cheap alternative that is not only abundant in nature but can also be produced comparatively faster than the ones that has maximum share in today’s market. Now the scientists also made resins that are biodegradable, so when both the resins and fillers are biodegradable this not only address the issue of cost but also that of recycling as well. The increase in environmental consciousness, energy crisis, and strict environmental regulations are shifting the focus towards cheap and sustainable composites.
