Design of an Impact Absorbing Composite Panel from Denim Wastes and Acrylated Epoxidized Soybean Oil based Epoxy Resins

Transesterification of epoxidized soybean oil to prepare epoxy methyl esters

Epoxidizedmethyl esters were prepared by the transesterification of epoxidized soybean oil (ESBO). The transesterification was complete in 10min at 50 ◦C without loss of the epoxide function. Epoxidized methyl esters represent a renewable substrate that is readily converted into surfactants, fuel additives, and other industrial products. The implementation of this reaction will increase the ava...

Solid freeform fabrication of epoxidized soybean oil/epoxy composite with bis or polyalkyleneamine curing agents

Extrusion freeform fabrication has been used to make bars of fiber-reinforced epoxidized soybean oil (ESO)/epoxy resin. Freeform fabrication methods build materials by the repetitive addition of thin layers. The mixture of epoxidized soybean oil (ESO) and epoxy resin are modified with a gelling agent to solidify the materials until curing occurs. The high strength and stiffness composites are f...

Thermal Stability and Impact and Flexural Properties of Epoxy Resins/Epoxidized Castor Oil/Nano-CaCO3 Ternary Systems

Epoxy ternary systems were prepared from the diglycidylether of bisphenol-A (DGEBA), epoxidized castor oil (ECO), and nano-CaCO3 using a thermally latent initiator. The effects of ECO and the nano-CaCO3 contents on the thermal stability and mechanical interfacial properties of the prepared DGEBA/ECO/nano-CaCO3 ternary systems were examined by thermogravimetric analysis (TGA), Izod impact tests,...

Acrylated-Epoxidized Soybean Oil-Based Polymers and Their Use in the Generation of Electrically Conductive Polymer Composites

Ring-Opening Polymerization of Epoxidized Soybean Oil

Ring-opening polymerization of epoxidized soybean oil (ESO) catalyzed by boron trifluoride diethyl etherate (BF3 OEt2) in methylene chloride was conducted in an effort to develop useful biodegradable polymers. The resulting polymerized ESO (PESO) were characterized using infrared (IR) spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), H NMR, C NMR, solid st...
