Polymer composites have a great scope which provides improvised mechanical and chemical propertiesthan matrix material. Although most composite materials are relatively strong, they are not sustainable. The sustainability and reusability of the material is significantly affected by the incorporation of nondegradablefillers. Bael bark is a naturally occurring material with numerous medical properties; in thisstudy, Bael bark was dried, synthesized and converted into nano-filler for integrating them in polylactide(PLA) matrix. PLA is a widely used biopolymer in the biomedical sector. The filler and matrix material areboth biodegradable; therefore, the resulting composite is also expected to be biodegradable. This studyaims to develop a composite comprising Bael bark and PLA, which is a better alternative to PLA in termsof strength and sustainability. Bael bark-reinforced PLA matrices were synthesized with different Baelbark compositions, i.e., 5 wt.%, 10 wt.%, 15 wt.%, and 20 wt.%. Subsequently, the resulting compositeswere subjected to filament characterization tests such as single fiber tensile test (SFTT), scanning electronmicroscopy (SEM), and X-ray diffraction (XRD). Notably, all extruded composites exhibited a uniform distributionof filler materials. Tensile, compression, and flexural tests were also conducted on the additivelyfabricated samples. The tensile strength, compressive strength and Flexural strength of composite specimenswere higher than neat PLA material, with increments of 39%, 33.8%, and 33.9%, respectively, for thecomposite made with 15 wt.% composites. Using a commercial finite element code ABAQUS, numericalsimulations were performed on tensile, compression and flexural specimens. The simulation resultsare in good agreement with the experimental results.
