Interactions and performance analysis of epoxidized palm oil/unsaturated polyester resin: Mechanical, thermal, and thermo-mechanical properties

Abstract: In this work, an alternative of bio-thermoset resin for composite applications was synthesized using unsaturated polyester resin (UPE) and epoxidized palm oil (EPO). The main purpose of this study is to reduce the dependency on petroleum and improve the toughness properties of UPE by partially introduced renewable source triglyceride, EPO in the UPE chain. The UPE resin blends with 10, 20, and 30 wt% EPO oil were synthesized by using benzoyl peroxide as an initiator. The samples were cured in an oven at 100°C … Show more

“…The peaks in the range of 1145 cm −1 and 1075 cm −1 were characterized by C–O stretching vibrations. It was necessary to separately mark the residual peaks at 982 cm −1 and 912 cm −1 related to the unreacted C=C groups of polyester and styrene, respectively [ 10 , 11 , 29 , 30 ]. The peak in the range of 700 cm −1 was associated with vibrations of the C–H bond, the intensity of which depended on the degree of composite curing.…”

“…Among different curing processes of UPR at different temperatures, there were three different types of initiators, which were low-temperature (40–70 °C) initiators [ 4 , 12 , 13 , 14 , 15 ], medium-temperature (70–130 °C) initiators [ 16 , 17 , 18 , 19 ], and high-temperature (≥130 °C) initiators [ 20 , 21 , 22 , 23 ]. Regarding commercial low-temperature initiators, there are cyclohexanone peroxide (CYHP), methyl ethyl ketone peroxide (MEKP), and benzoyl peroxide (BPO), which were applied together with accelerators [ 12 , 24 ].…”

“…Regarding commercial low-temperature initiators, there are cyclohexanone peroxide (CYHP), methyl ethyl ketone peroxide (MEKP), and benzoyl peroxide (BPO), which were applied together with accelerators [ 12 , 24 ]. Regarding medium-temperature initiators, tert-butyl peroxy-2-ethylhexanoate (TBPO) and benzoyl peroxide (BPO) are the two typical examples [ 16 , 18 ]. In the range of high temperatures, tert-butyl peroxybenzoate (TBPB), peroxy ketone peroxide, and peroxy carbonate (BIC) are the three typical commercial initiators [ 23 , 25 ].…”
