Abstract
A Bio composite comprising Prosopis Juliflora Fiber (PJF) and Poly Lactic Acid (PLA) was processed considering two particulate sized reinforcements, coarse PJF (avg. 15 µm) and fine PJF (10-50 nm). They were added individually at ratios of 10, 15, 20 and 25 wt% into PLA matrix. The composites were extruded and tested for mechanical properties. The addition of PJF resulted with an increase in the tensile, flexural and impact strengths of the polymer. Adding PJF to PLA showed a decrease in the hardness of the polymer. Water Absorption test showed an increase in water uptake with increasing fiber content. The most optimum ratio of PLA to PJF was found to be 80:20. The fine PJF reinforced composites proved to be superior over the coarse PJF reinforced composites at all stages of the research. FESEM and TGA were used to study morphology and thermal characteristics respectively.
Highlights
Non biodegradable polymers and composites have always composites are currently being used in versatile applications been a difficult task when it comes to waste management, like aircraft and automobile interiors, medical implants, they are not decomposable and pose a major threat towards 3D printing and other biomedical equipment[4,5].land pollution
Prosopis Juliflora (PJ) is currently used as fire biomaterials as an alternative to non-biodegradable plastics wood and its fruit as animal fodder
The wood fiber strings were alkali treated for 12 hours in a solution containing 95% water and 5% NaOH[17,18] to enhance the adhesion of the fiber with the matrix
Summary
Non biodegradable polymers and composites have always composites are currently being used in versatile applications been a difficult task when it comes to waste management, like aircraft and automobile interiors, medical implants, they are not decomposable and pose a major threat towards 3D printing and other biomedical equipment[4,5].land pollution. Prosopis Juliflora (PJ) a medium sized tree found hand, plastic materials derived commonly from agro products in the tropical zones around the globe and abundantly like cassava, sugarcane and beet[1]. These bioplastics undergo available in South Asia, South America and Africa. It is complete decomposition when they are buried, thereby considered as a weed to be eradicated due to its abnormal helping to avoid land pollution. PJ is currently used as fire biomaterials as an alternative to non-biodegradable plastics wood and its fruit as animal fodder.
