3D Printing using Cellulose Nanoparticles
Dhakal, H. N.; Ismail, S. O.; Andrew, J. J. (Royal Society of Chemistry, 2020-09-09)Cellulose is naturally available and most abundant biopolymer on earth. It is one of the main constituents of cellulosic materials, such as wood, plant fibres (flax, hemp, jute), among others. Due to their high surface ... -
Abrasive water jet drilling of advanced sustainable bio-fibre-reinforced polymer/hybrid composites : a comprehensive analysis of machining-induced damage responses
Dhakal, H. N.; Ismail, S.O.; Ojo, S. O.; Smith, J. R. (2018-12-01)This paper aims at investigating the effects of variable traverse speeds on machining-induced damage of fibre-reinforced composites, using the abrasive water jet (AWJ) drilling. Three different types of epoxy-based composites ... -
Characterization of Nano-Mechanical, Surface and Thermal Properties of Hemp Fiber-Reinforced Polycaprolactone (HF/PCL) Biocomposites
Dhakal, H. N.; Ismail, S. O.; Beaugrand, J.; Zhang, Z.; Zekonyte, J. (2020-04-10)The quest for sustainable, low-cost and environmental friendly engineering materials has increased the application of natural fiber-reinforced polymer (FRP) composite. This paper experimentally investigates the effects of ... -
Development of sustainable biodegradable lignocellulosic hemp fiber/polycaprolactone biocomposites for light weight applications
Dhakal, H. N.; Ismail, S.O.; Zhang, Z.; Barber, A.; Welsh, E.; Maigret, J. E.; Beaugrand, J. (2018-10-01)Biocomposites with poly(ε-caprolactone) (PCL) as matrix and lignocellulosic hemp fiber with varying average aspect ratios (19, 26, 30 and 38) as reinforcement were prepared using twin extrusion process. The influence of ... -
Influence of barely visible impact damage on post-impact residual flexural properties of hybrid Fibri Rock – Aero Eco-composites
Dhakal, H. N.; Ismail, S. O.; Jiang, C.; Sweatman, T. (2018-12-15)This study experimentally investigates the effects of barely visible impact damage (BVID) under low-velocity impact and its influence on post-impact residual flexural properties of hybrid flax-basalt Eco-composites Fibri ... -
Machinability of Bio-composites: Challenges and Prospects
Ismail, S. O.; Dhakal, H. N. (2nd Conference_FLOWER Project, Advanced Biobased Materials and Composites for Engineering Applications, University of Portsmouth, England, UK, 2020-09-17)The exceptional inherent properties of natural fibre reinforced polymer (FRP) composite materials and their bio-based hybrid counterparts have contributed to extensive engineering applications. These properties include, ... -
