Abstract
Natural fiber-based composites are essential to everyday life from the simplest building
components to those used in the construction and automotive industries. In this research, the
effects of adding nanoclay to epoxy lannea coromandelica (ELC) composites with cotton fiber
reinforcement are examined. Using a mechanical stirrer, nanoclay (N) is introduced to ELC resin as a
nano reinforcement in weight fractions percentages (0, 1, 2, 3, 4 and 5). It is chosen to use woven
cotton (C) fiber mat as secondary reinforcement. Hardener HY951 (1 %) is added in specific volume
fraction to ELC resin and nanoclay mixture. Following that, hand layup (HLU) process is used to make
cotton fiber infused epoxy Lannea Coromandelica (CFRELC) composites. Testing is done on samples
to determine their thermal conductivity, biodegradability, compression qualities and DMA analysis.
Utilizing a scanning electron microscope, researchers look at the Fractography analysis of
compressive fracture in hybrid composites. The ELC resin reinforced with cotton fiber and containing
4 wt% nanoclay has shown the best mechanical capabilities.
