“…Badrinarayanan studied the cure kinetic of soybean oil-ST-DVB copolymer system and found that this system is suitable for pultrusion due to its fast curing speed [48]. Chandrashekhara et al used the pultrusion process on the blend of epoxidized allyl soyate (a mixture of epoxidized fatty acid ester) and Epon 9500 (a commercially available epoxy resin designed for pultrusion) to produce glass fiber reinforced composites [49]. It was found that incorporation of 10-20 wt% of epoxidized allyl soyate into epoxy yielded a material with a toughness that is much higher than pure epoxy [49].…”

“…Poorer thermal and mechanical properties result from both partially unreacted ESO and saturated fatty acid (FA) chains that reduce reactivity and self-plasticize. Most ESO industrial uses are thus limited to nonstructural, additive applications such as plasticizers or stabilizers for poly (vinyl chloride) [13], oil-base coatings [14] with low strength requirements [15]. Though the mechanical strength of cured ESO can be improved with the addition of nano-reinforcements [16], or fiber reinforcement [17], an inherently low T g inevitably limits practical applications because T g for a polymer must be appropriately higher than the temperature of its intended work environment to serve as a useful plastic [18].…”

Abstract. Glycidyl esters of epoxidized fatty acids derived from soybean oil (EGS) and linseed oil (EGL) have been synthesized to have higher oxirane content, more reactivity and lower viscosity than epoxidized soybean oil (ESO) or epoxidized linseed oil (ELO). The EGS and ESO, for comparison, were used neat and in blends with diglycidyl ether of bisphenol A (DGEBA). Thermosetting resins were fabricated with the epoxy monomers and either BF 3 catalyst or anhydride. The curing behaviors, glass transition temperatures, crosslink densities and mechanical properties were tested. The results indicated that polymer glass transition temperatures were mostly a function of oxirane content with additional influence of glycidyl versus internal oxirane reactivity, pendant chain content, and chemical structure and presence of saturated components. EGS provided better compatibility with DGEBA, improved intermolecular crosslinking and glass transition temperature, and yielded mechanically stronger polymerized materials than materials obtained using ESO. Other benefits of the EGS resin blend systems were significantly reduced viscosities compared to either DGEBA or ESO-blended DGEBA counterparts. Therefore, EGS that is derived from renewable sources has improved potential for fabrication of structural and structurally complex epoxy composites, e.g., by vacuum-assisted resin transfer molding.

“…According to Chandrashekhara et al (2005), among the composite fabrication techniques like injection molding, pultrusion, extrusion and filament winding, pultrusion ( Fig. 1) technique has been found to show better improvement in composite properties during processing because the fibers are pulled under tension when they entered the die as the reinforced composites are cured (Chandrashekhara et al, 2005).…”

Pultrusion is the one of technologies to fabricate the polymer composites to be used in many industries such as in aerospace, automotive and construction industries. The high performance pultruded products that are produced by this technique offer high fibre content of at least 70%. In order to produce high quality pultruded profiles, there are variables such as fibre impregnation, resin viscosity, pulling speed and curing temperature that have to be considered and these variables are discussed in this study. The review on the recent research in pultrusion process, types of resins used in pultrusion process and mechanical properties of pultuded composites are presented.
