Hybrid polyester composites using Ocimum gratissimum stem fiber and mussel shell derived calcium carbonate as reinforcements
The present study investigates the development of sustainable hybrid polyester composites reinforced with 30 vol% Ocimum gratissimum stem fiber and mussel shell-derived calcium carbonate (CaCO₃) for lightweight structural applications. The extracted natural fiber and bio-derived CaCO₃ particles were surface modified us...
