Development of soybean oil‐based composites by solid freeform fabrication method: Epoxidized soybean oil with bis or polyalkyleneamine curing agents system

Abstract

Soybean oil-based composites are prepared by the solid freeforming fabrication (SFF) method. Epoxidized soybean oil is solidified with a gelling agent, and composites are formed by fiber reinforcement. Glass, carbon, and mineral fibers are used in the formulations. The type of fiber and degree of fiber alignments affect the properties of the composites. In addition, the effects of curing agents, curing temperature, fiber combination, and fiber loading on mechanical properties of composites and dynamic analysis are studied and reported.

Fully biodegradable natural fiber composites from renewable resources: All-plant fiber composites

“…Some researchers compounded plant fibers with biodegradable polymers including poly(lactic acid) [4], starch plastics [5], soybean plastics [6] and cellulosic plastics [7] for producing fully biodegradable composites. As these biodegradable polymers based on food and feed are relatively costly, their potential application as the matrices of structural composites has to be confined to some specific area with high value-added.…”

Investigation of the surface properties of polymeric soaps obtained by ring‐opening polymerization of epoxidized soybean oil

“…The main fatty acid composition of soybean oil is (w/w): linoleic (54), oleic (23), and linolenic (8). 6 These fatty acids contain 2, 1, and 3 double bonds, respectively, in their hydrocarbon chains.…”

“…[7][8][9] Some of these methods involve the synthesis of new materials from soybean oil using chemical, enzymatic, thermal, or other methods. This is possible because soybean oil comprise two reactive sites for this purpose.…”

Effects of different epoxidation methods of soybean oil on the characteristics of acrylated epoxidized soybean oil-co-poly(methyl methacrylate) copolymer

“…been polymerized to form plastic materials such as ESO-co-styrene/divinylbenzene resins [13][14][15][16][17][18], ESO thermosetting allyl resins [19], a sheet molding compound resin [20], and a hydrogel [21], or even polymer composites such as an organo clay nanocomposite [22], and fiber-reinforced composites [23][24][25]. According to Hazer and coworkers [26][27][28][29][30][31][32][33], vegetable oils were autooxidized by exposure to sunlight or daylight in air for a given time to produce epoxides, peroxides, peroxides, and hydroperoxides in the molecular chains and were also graft copolymerized by free radical polymerization with other materials such as methyl methacrylate and styrene.…”
