Experimental Investigation and Fabrication of Palmyra Palm Natural Fiber with Tamarind seed powder Reinforced Composite

Abstract

The usages of composite materials in industries are become as a growing trend due to their inherent material properties such as good strength, low thermal expansion and high strength-to-weight ratio. Among the many classifications of composite materials, natural fiber composites are generally preferred due to their unique characteristics such as bio-degradable property towards the environment. In this study, based on the above selection criteria, from Borassus Tree trunk, Palmyra palm fiber and tamarind powder is selected for the study to use the same for practical application. During this course of examination, tamarind seed powder along with the exact proportionate of Palmyra palm fiber (treated and untreated) has been taken as the reinforcement, similarly epoxy resin has been chosen as the matrix material. To thoroughly validate the physical strength of the individual combination, five set of specimens were fabricated (treated and untreated) as well as their physical strengths such as tensile, flexural, impact and moisture absorption tests were evaluated. Out of all the tests, treated fibers wer shown the better upsurge in tensile, flexural, impact and moisture tests as against the untreated fibers.

Effect of ketal group in castor oil acid‐based plasticizer on the properties of poly(vinyl chloride)

“…From Figure 3(a), it is clearly discerned that PVC‐D, PVC‐C, and PVC‐K displayed only one tan δ peak, suggesting that these plasticizers had good compatibility with PVC matrix. The T g values of PVC‐D, PVC‐C, and PVC‐K were 22.3, 40.5, and 20.6°C, respectively, while the T g value of pure PVC was in the range of 80–90°C 8,19–22 . According to the free volume theory of plasticization, the molecule of plasticzier possesses the ability to reduce interactions between PVC chains and increase the free volume between the polymeric chains.…”

“…Also, phthalates have been banned in certain applications due to the high risk of toxic and biological effects on the humans, and phthalates are usually generated from petroleum resources 13–15 . Therefore, to find a substitute for conventional DOP with comparable performance, nontoxic plasticizers based on sustainable resources have attracted a lot of attention in recent years, 16–18 with biobased resources receiving much attention due to their nontoxic and sustainable characteristics 19–21 . As a result, numerous alternative plasticizers derived from biobased resources, have been developed, including fatty acid esters, 22,23 tung oil, 24,25 soybean oil, 26,27 isosorbide, 28,29 castor oil, 30–32 and tartaric acid 33 .…”

Mechanical and Water Absorption Characterization of Mango Seed Shell/Epoxy Composite for Low Load Carrying Structures

“…Lapox L-12 is a liquid, unmodified epoxy resin of medium viscosity used with various hardeners for making compos-ites. The Lapox L-12 resin has a density in the range of 1.12-1.19 g/cm 3 , dynamic viscosity in the range of 50-95 MPa s, flash point greater 200 °C, and storage temperature in the range of 2-40 °C as per the technical specification datasheet provided by the supplier.…”

“…Mechanical properties such as tensile, impact, and flexural strength are observed to increase, when palm fiber and tamarind seed paste are used as reinforcements in the epoxy resin [3]. The composites are synthesized using randomly dispersed groundnut shell particles of various grain sizes and an epoxy resin matrix, and it is discovered that grain size has a significant influence on the mechanical characteristics of the composite, viz., the tensile and impact strength characteristics [4].…”

Selected engineering properties of palmyrah (Borassus flabellifer) leaf base

“…The palmyrah fibre (treated and untreated) reinforced epoxy composite, added with tamarind seed powder acts as a particulate composite. The mechanical properties of untreated to treated fibre composites increased from 33 to 67 per cent due to good adhesion between fibre, tamarind seed powder, and matrix material (Srinivasan et al, 2020).…”
