The mechanical characteristics of PLA (Polylactic acid) composites with fly ash and tamarind kernel powder micro fillers were examined in this experimental investigation. Samples were created by changing the amount of tamarind kernel particles from 0 to 4 wt.% when using PLA as the binder (with an increment of 1 wt.% for each sample). Fly ash filler’s wt.% was left at 1. Compression moulding was used to create composites. According to the tensile results, the reinforcement using fly ash and tamarind kernel powder greatly increased the PLA matrix’s tensile strength. At 1 wt.% fly ash and 2 wt.% tamarind kernel powder composites, respectively, the maximum tensile, flexural, impact, tensile modulus, and flexural modulus of 76.24 MPa, 156.68 MPa, 18.61 kJ/m2 , 2.31 GPa, and 3.86 GPa were attained. The impact and flexural strength of PLA matrices were significantly improved by the particle reinforcements of fly ash (1 wt.%) and tamarind kernel powder (2 wt.%). Additionally, when compared to plain PLA, the composites with fly ash particles showed a 30% increase in microhardness. Additionally, the results showed that an important factor in determining the characteristics of PLA composites is the wt.% of fillers.
