Effect of epoxidized soybean oil on mechanical properties of woven jute fabric reinforced aromatic and aliphatic epoxy resin composites

Abstract

A systematic study was performed to describe the effect of epoxidized soybean oil (ESO) on storage modulus, glass transition temperature (Tg) and mechanical properties in epoxy resin composites reinforced by jute fabric. In addition to aromatic diglycidylether of bisphenol‐A (DGEBA) resin, a glycerol (GER)‐and a pentaerythritol (PER)‐based aliphatic resin was applied as base resin, which can be also synthesized from renewable feedstock. Based on strip tensile test results, the usual alkali treatment of jute fabric was avoided. By increasing the ESO‐content in aliphatic composites the Tg increases, whereas in case of DGEBA, it decreases. The results indicate that although ESO has a significant softening effect, the jute fiber‐reinforced DGEBA composite can be replaced without significant compromise in mechanical properties by a potentially fully bio‐based composite consisting of 25 mass% ESO‐containing aliphatic PER‐reinforced by jute fibers.

Hybrid bio-based composites from blends of epoxy and soybean oil resins reinforced with jute woven fabrics

“…The rapid tensile strength decrement of the 50BIO sample at both testing directions may result from the excess resin content as mentioned in the physical analysis (table 3). The tensile strength of composite materials which have above 50 wt% AESO content in the aliphatic epoxy matrix is decreased to the half because of the over plasticization caused by the higher content of flexible aliphatic long chains of AESO resin [27,28].…”

“…In the literature, the studies related to the AESO based composites mostly focus on the use of AESO in a mixture of several matrix types such as styrene [10,25], polyester [11,26], vinyl ester [7], epoxy [25][26][27], etc. There are only a few studies in the literature that works on natural textile fiber reinforced composites consisting of soybean oil resin and epoxy resin in order to improve the toughness of the neat epoxy composites [27][28][29]. In one of the studies, Bakar et al (2018) mixed epoxidized soybean oil with petroleum-based epoxy resin in different ratios to investigate its effects on mechanical (tensile, impact and flexural strength) and thermal properties.…”

Influence of epoxidized linseed oil and sisal fibers on structure–property relationship of epoxy biocomposite

“…Many researchers have focused attention on the development of petroleum‐based thermoset composite reinforced with sisal fibers (SFs) primarily to target the automotive and structural applications because of low density and specific properties of later . Although various attempts in making plant oil‐based green composites reinforced with natural fibers have been reported in the last decade, the use of SFs in development of the vegetable oil‐based green composites is limited .…”

Characterization of high glass transition temperature sugar-based epoxy resin composites with jute and carbon fibre reinforcement

“…EHO and ESO jute-based samples displayed similar tensile behaviour at a concentration of 10 mass% bioresin, a significant reduction in mechanical properties occurred after 30 mass% bioresin content. Niedermann et al [24] investigated jute reinforced biocomposites from ESO and their blends with DGEBA, a glycerol-and a pentaerythritol-based aliphatic epoxy resin. Up to 25 mass% ESO-content the mechanical properties were comparable to the reference composites'.…”

“…As natural sourced reinforcement woven jute fabric was chosen. According to the previous results [24,28], before the composite manufacturing no alkali treatment was applied on the woven jute fabric. As reference reinforcement woven carbon fabric (CF) was used.…”
