Charpy impact test on sisal woven fiber reinforced novel graphene nanoparticles composite on automotive applications.

The primary goal of this work is to increase and compare the impact strength of Sisal fiber-reinforced epoxy composites with and without graphene filler. Sisal fibre is employed as a reinforcement material using graphene as a filler. This investigation requires sisal fibre 220GSM, resin (LY559), and hardener (HY951). The laminate was made using the hand lay-up technique. Twenty samples (N=20) were collected in an experimental and control group. The Charpy impact test was performed on sisal fibre without filler, sisal fibre with graphene 2% and 4% filled composites. The Charpy impact testing equipment was used for testing, according to the V-shaped notch. The sisal fibre epoxy composite had an impact strength of 2.8 J. The impact strength of a sisal fibre epoxy composite containing 2% graphene filler and 4% filler was 2.9 J and 3.8 J, respectively. The statistical significance of sisal fibre graphene filler reinforced epoxy composite was determined using SPSS-V26 software and was 0.0001 (p<0.05). Within the scope of this work, graphene composites containing 4% sisal fibre demonstrated much greater impact strength than sisal fibre epoxy composites. [ABSTRACT FROM AUTHOR]
