Accelerated weathering analysis of jute reinforced cashewnut shell liquid modified soy based green composite

In this work, both glass fabric and jute fabric reinforced nanoclay modified soy matrix-based composites were developed and characterized. Glass fabric (60 wt.%) reinforced composite showed maximum tensile strength of 70.2 MPa and thermal stability up to 202°C, which are 82.8% and 12.2% higher than those observed with corresponding jute composite. Water absorption and contact angle values of glass-soy specimens were tested, and found composites are water stable. Biodegradation study of composites under soil burial condition revealed that glass-soy composite with 40 wt.% glass fabric lost maximum 32.6% of its original weight after 60 days of degradation. The developed glass fabric-soy hybrid composites with reasonable mechanical, thermal, and hydrolytic stability can be used in different sectors as an alternative to the nondegradable thermoplastic reinforced glass fabric composites.

“…Alkali treated jute-soy (AJS) composite was developed by thermopressing soy resin-soaked jute felts at 120 C, under 12-ton pressure for 10 min. [9] Various weight fractions of Cloisite 15A (1-10 wt.% of solid soy resin) were dispersed in acetone (25 ml) by stirring for 30 min using a magnetic stirrer. The prepared soy resin was then added to each nanoclay (Cloisite) dispersed solution and stirred well for 25 min to yield the Cloisite modified soy (CMS) resins.…”

“…Biodegradation tests on the AJS, JCS1, JCS5, and JCS10 composites were carried out in compost bed as per BIS1623-92. [9 Compost bed was prepared by mixing cowdung, sand, and soil in a 1:1:2 manner and an appropriate amount of water was sprinkled to keep moisture about 30%. Composites were kept under a compost bed and incubated in a chamber with an average temperature and relative humidity of 32 C and 80%, respectively.…”

“…4 wt.% CNSL content composite exhibited tensile strength of 52 MPa, and water sorption of 52.1% after 24 h water immersion due to jute's hydrophilic nature. [9] High water sorption and low mechanical properties of jute reinforced biocomposites are the major draw backs to be nonadoptable in place of plastic. By using proper additives, or modification by nanofillers, physical, and mechanical properties of bio-resin can be enhanced.…”

Nanoclay modified bio resin-based jute composites were prepared by thermopressing method to examine the effect of nanoclay on physical, mechanical, and biodegradation properties of jute-soy composite. Fourier transform infrared spectroscopy of composite was carried out to study the chemical interactions between jute-soy-nanoclay, whereas, x-ray diffractogram and transmission electron microscopic analysis revealed the formation of nanostructure at the composite interface. With 5 wt.% of clay contents, the tensile strength of the composite was 59.2 MPa, which is 65.4% higher than that of the clay-free jute-soy composite. The developed composite is thermally stable up to 280 C and increased in weight by only 41.66% after 24-h water immersion. Inclusion of 5 wt.% nanoclay enhanced storage modulus of nanocomposite from 1170 to 4136 MPa. Evaluation of degradability of composites under compost condition in terms of weight and tensile loss indicated that clay reinforced composites are more durable than jute-soy composite. Overall, a biodegradable composite material was developed which may be applied as nondegradable plastic alternate in packaging, railway coach, decorating materials, furniture, transport, and construction sector.

Tribo-mechanical properties of epoxy-cashew nut shell liquid-crumb rubber- friction dust-banana fiber composites

Epoxy-cashew nut shell liquid (E-CNSL) composites are prepared by open resin moulding method with varying CNSL content (16 to 30 vol. %.). The tensile properties, hardness and impact strength of E-CNSL composites were investigated as per ASTM standards. It is found that the addition of the CNSL in epoxy increases the elongation at break and tensile strength. The 16 vol. % CNSL addition showed maximum tensile strength, and further increased CNSL deteriorates the tensile properties of the resultant composites. Further, hybrid composites are prepared by reinforcing crumb rubber (CR), short banana fibre (BF) and friction dust (FD) in cashew nut shell liquid (CNSL) mixed epoxy. The samples were tested as per ASTM standards to investigate the basic mechanical properties. It is found that the hybrid composite made of 2.5 vol. % CR, 2.5 vol. % FD and 7.5 vol. % BF in epoxy with 16 vol. % of CNSL showed better properties. Further, the specific wear rate, coefficient of friction and rate of water intake is investigated for the hybrid composite and reported.
