This inquiry focuses on the moisture absorption properties of a novel coconut shell biochar- and filler-free flax fiber-reinforced vinyl ester biohybrid composite. The composite is a biohybrid. Materials and Methods of Procedure: A total of forty samples were utilised in this investigation of the water absorption capabilities of flax fibre composites. Group 1 was comprised of flax fibre and vinyl ester, and it had a sample size of twenty. Group 2 was comprised of flax fibre, vinyl ester, and coconut shell biochar, and it also had a sample size of twenty. Findings: The experimental examination into flax fibre reinforced composites with filler demonstrates lower minimum values when compared to the findings obtained without the use of filler. In order to determine the sample size for each group, a G-power of eighty percent was utilised. The numbers that are averaged out are 4.3734 and 2.3777 respectively. A change in the water absorption of the flax fibre composite was observed, and this shift was statistically significant (p=0.001). A statisticall y significant distinction may be made between the two groups, which are distinct from one another. According to the findings, flax fibre reinforced vinyl hybrid composites without fillers perform very well in comparison to flax fibre reinforced vinyl ester composites with fillers, which are known to effectively absorb a significant amount of water. The eco-friendliness of the fibre composite is preserved as a result of this. It was found that the flax fibre composite exhibited a change in water absorption that was statistically significant (p=0.001).
