Cotton-Epoxy Composites: Development and Mechanical Characterization

Abstract

Composites are becoming essential part of today’s material because they offer advantages such as low weight, corrosion resistance, high fatigue strength; faster assembly etc. composites are generating curiosity and interest all over the worlds. The attempts can be found in literature for composite materials high strength fiber and also natural fiber like jute, flax and sisal natural fibers provides data but there is need of experimental data availability for unidirectional natural fiber composite with seldom natural fiber like cotton, palm leaf etc., it can provide a feasible range of alternative materials to suitable conventional material. It was decided to carry out the systematic experimental study for the effect of volume fraction of reinforcement on longitudinal strength as well as Modulus of Elasticity (MOE) using developed mould-punch set up and testing aids. The testing is carried out as per ASTM D3039/3039M-08. The comparative assessment of obtained experimental results with literature is also carried out, which forms an important constituent of present work. It is also observed through SEM images and theoretical investigations that interface/interphase plays and important role in natural fiber composite.

Fully Bio-Based Epoxy-Amine Thermosets Reinforced with Recycled Carbon Fibers as a Low Carbon-Footprint Composite Alternative

“…A means to overcome the dependency on non-renewable resources is to consider low-carbon footprint fibers. In that regard, natural fibers have been considered as a replacement of glass fibers. ,, Natural fibers obtained from biomass feedstock have thus emerged as good candidates as composite reinforcement, specifically jute, cotton, , bamboo, hemp, and nanocellulose fibers . These fibers have been used as reinforcement for petrosourced, − partially biosourced, − or fully biosourced thermosets. ,− Nevertheless, three main drawbacks arise from these studies and their usage.…”

Plant Fibers-Based Sustainable Biocomposites

“…The cotton-polymer composite system made contributions to the war effort during 1941-1946, as fiber-reinforced plastics; it was first used by the military for radar domes on aircraft. In cotton-reinforced epoxy composite the fiber volume fraction increases the strength as well as longitudinal modulus of elasticity (MOE) increases linearly [9]. Similar change in properties is noticed with cotton polyester composite [81].…”

“…During the 1970s and 1980s natural fibers were partially replaced by petrochemical polymers due to their optimized properties and their faster manufacturing processes. In the mid-1980s it had been thought that the utilization of natural fiber-reinforced composites could offer an interesting alternative to plastics due to their technical, economic, and ecological advantages and social benefits [9]. In the 1970s the composites industry began to mature.…”
