Development and characterization of bio-composites using senegalia catechu resin

Abstract

Owing to the increase in demand on bio-degradable materials, the present researches focus on the development of materials with full degradability. This research is intended to develop a bio-resin–based composite from senegalia catechu gum for light load automotive applications. The bio-resin obtained from the plant is processed with commercial polyester in order to make it as a functional resin for composite preparation. The synthesized resin is made in the form of structural materials by adding jute reinforcements in varying proportions. An extensive study on the various characters in comparison with the synthetic resin–based composites has been done which includes mechanical strengths analysis and thermal characters investigation. It is revealed that the bio-resin–based composites are good against tensile, flexural and impact loads as compared to that of the synthetic resin composites. In addition, it has been witnessed that the material with 40% weight of jute fabric is apt for offering highest resistance against tensile, flexural and impact loads. Micro-structural investigations proved that the bio-resin–based composites are superior in reducing the flaws and enhancing the bonding of resin with fibres as compared to that of the synthetic resin-based composites. Further, the thermal characterization showed that the bio-resin–based composites have high thermal stability as compared to the synthetic composites, and hence, a positive sign is obtained for bio-resin–based composites in both mechanical and thermal characters.

Tribological Behaviour of Novel Green Resin Based Composites

“…The responses have been configured to minimize between the minimum and maximum readings, whereas the input parameters have been adjusted to a range between minimum and maximum values. The ideal condition with a desirability close to 1 was chosen among the list of optimum conditions when optimization was done using the desirability approach [50][51][52]. The results show that the best conditions are a load of 5 N, a speed of 3 m/s, a sliding distance of 1000 m, and the selection of sample 3, with a maximum desirability of 0.942.…”

“…In FTIR amide groups were increased and thermal stability also improved. Vinayagamoorthy and Venkatakoteswararao 22 development and characterization of bio-composites using senegalia catechu resin. They reported a positive sign in bio resin-based composites to have superior mechanical and thermal characteristics as compared to synthetic composites.…”

“…14 Bio-polymer composites which are more environmentally friendly and recyclable materials offer less weight, high strength, anti-corrosion, etc. 15,16 The plant resins are such as tamarind, 17 soy protein, 18 wheat protein, 19 banana sap, 20 corn, 21 catechu, 22 karaya, 23 guar, 24 kondagogu gum, etc. 25–28 These resins have resulted in improved mechanical properties and reduced overall weight, which enhances the ease of production and decreases the cost.…”

Experimental Study of Fiber Orientation on the Mechanical Properties of Glass Fiber Reinforced Thermoplastic Composites

“…They have indicated that non -woven veils could affect the tolerance of laminates under hot -wet conditions. Vinayagamoorthy et al [14] have made an investigation to study the characteristics of composites employing natural resin. They have reported that the fiber orientation and fiber composition have played a vital role in deciding the strength characteristics of specimen laminates.…”
