About
Mr. Subrata Chandra Das is currently working as a PhD Candidate at the Advanced and Sustainable Engineering Materials Laboratory (ASEM-lab) under the research group of Sustainable Composites, Department of Manufacturing and Civil Engineering (IVB), NTNU, Gjøvik. His doctoral research mainly focuses on developing sustainable composite materials from natural fibers (flax) and bio-derived and/or recyclable novel polymer matrices (both thermosets and thermoplastics) and assessing their long-term performance under different environmental conditions. Professor Sotirios Grammatikos (Director of ASEM-lab) is the main advisor of his doctoral research work.
Doctoral thesis title:
“Advanced natural fiber reinforced polymer composites for various applications”
Summary:
Natural fiber reinforced polymers are currently at the forefront of research worldwide, in the field of composite materials, due to the ever-increasing effects of climate change but also the imposition of environmental regulations to reduce CO2 emissions. Natural fiber reinforcements have been found to offer useful properties for polymer composites in different applications, such as low density, high specific stiffness, renewability, availability, biodegradability, and non-toxicity. As for the matrix, bio-based polymers and recyclable polymers have also shown great potential to replace currently used synthetic and/or fossil- or petroleum-derived polymers. Due to their advantageous properties, conventional composites have invaded the market in many sectors, however, they consist of synthetic reinforcements and petroleum-based polymers, due to their low cost but also to withstand different service conditions. However, the environmental impact of these composites is quite large, due to both the origin of the constituents, but also the lack of treatment solutions for recycling/reuse of End-of-Life conventional composites.
The current scientific knowledge on long-term performance and behavior of natural fiber reinforced composites, with bio-based and recyclable polymer matrices, when exposed to various service environments is very limited. Therefore, this PhD work is aimed to provide knowledge on the long-term behavior of composites consisting of natural fiber reinforcements together with bio-based and recyclable polymers. More specifically, the work studies flax fiber reinforced polymer composites, using two sustainable options of polymer resins (i) recyclable bio-based epoxy resin, and (ii) recyclable novel acrylic thermoplastic liquid resin in comparison with a standard conventional petroleum-based epoxy resin system and E-glass fiber reinforcement. For the manufacturing of the composite laminates, compression molding is employed, for composites that can be used in semi-structural and structural applications such as sports, automotive, wind energy, infrastructure, etc. To evaluate the long-term performance of the developed materials, case-tailored accelerated aging protocols are being designed to perform lab-based simulated artificial environmental aging on composites. The behavior of the studied composites after simulated aging is examined mechanically, physico-chemically and by fractography to characterize and analyze the effects of aging at the material level, with a view to develop knowledge on long-term behavior and allow predictions of service life. Finally, a feasibility study is performed by eco-design and life cycle assessment (LCA), in the case of (i) skis, and (ii) short wind turbine blades.
