“…The characteristic absorption peaks of epoxide groups and the ether bonds in the structure are shown at 915 and 1245 cm −1 bands, respectively. Moreover, the aromatic rings in neat epoxy resin are assigned at 1607, 1511 and 829 cm −1 [55].…”

In our world, where environmental factors are taken into consideration more and more, the interest in biomaterials leaves its place to the need and this leads the researchers to search for new materials. The aim of this study is to produce an environmentally friendly, sustainable material with the use of a plant oilbased bio-resin (acrylated epoxidized soybean oil). In this context, bio-composites containing different proportions (from 0 to 100 wt%, in 10% increments) of acrylated epoxidized soybean oil (AESO) and epoxy resin are reinforced with four-ply jute woven fabric and produced by the vacuum infusion method. The bio-composites produced within the scope of the study analyzed physically (fiber weight ratio), mechanically (tensile strength, flexural strength, drop-weight impact resistance, and Charpy impact strength), instrumentally (differential scanning calorimetry and Fourier-transform infrared spectroscopy) and morphologically (scanning electron microscopy). According to the results, the tensile and flexural strength values of the composites containing more than 30 wt% AESO resin decrease due to the ductility of the structure; subsequently, composites with AESO content above 50 wt% are found to exhibit superior impact resistance. Composites with pure AESO resin absorb 7 J energy which is almost 3 times higher than pure epoxy composites. The maximum tensile strength (63 MPa) of composites are achieved for 30 wt% AESO content indicating the newly formed hydrogen bonding leading to enhanced fiber-matrix interface. The bio-composites designed and produced in the project have been a promising alternative for various end-use areas, from construction elements to the automotive sector and sports equipment, where human health and environmental elements are considered.

“…Besides that, palm oil showed a peak at 1748 cm -1 for C=O stretching, whereas, in the case of synthesized resin that appeared at 1735 cm -1 . Apart from that, characteristic peak at 743 cm -1 corresponds to C-H bending of aromatic ring contributed by phthalate units 28 ; confirmed the formation of alkyd resin via polyesterification process 23,27 . Furthermore, the stretching frequencies of the spectra of A0 (Figure 4, curve ii) and A200 ( Figure 4, curve iii) were almost the same.…”

“…Alkyds have the disadvantages including lack of hardness, low hydrolytic stability, poor alkali resistance, poor exterior weatherability and color retention which diminished alkyd usage (37). Thus modifications of alkyds are imperative for the application.…”
