Abstract

The focus of this research is to study the effect of strain rates on the mechanical behaviour of P ALF reinforced PLA biocomposite. This research investigates the effect of test speed on the mechanical behaviour of the biocomposite when subjected to both quasi-static and dynamic loading. The specimen used in this project is P ALF reinforced PLA biocomposite and three type of testing were carried out including Quasi-static indentation testing, drop weight impact testing and surface morphological analysis using SEM. In this study, quasi-static indentation test are carried out at two different velocities which are 1 mm/min and 2 mm/min. Drop weight impact test are carried out at velocities 1 m/s, 1.5 m/s, 2 m/s, 2.5 m/s, 3 m/s and 3.5 m/s. From the result velocity l mm/min for quasi-static indentation test had maximum peak force which value 2480. 56 ± 88.55 N. In drop weight impact test the maximum peak force at speed 2.5 m/s which value 825.2 ± 86.89 N and total energy absorbed is 5.79 ± 0.67 J. From the results, maximum force and energy against time are directly proportional. The load and energy increased with in increasing time. Several type of damages were absorbed under both impact test and this include upper skin failure, skin core debonding and core crushing.
