TLDR
In addition to the natural formation of epoxy-bearing oils, the double-bond functionality in ordinary triglyceride oils can be epoxidized as discussed by the authors, enabling the easy formation of polyesters and polyurethanes.Abstract:
Although most triglyceride oils contain only double bond functionality, a few oils such as castor oil, vernonia oil, lesquerella oil, etc., contain other functional groups. These functional groups include hydroxy and epoxy groups, permitting the easy formation of polyesters and/or polyurethanes. In addition to the natural formation of epoxy-bearing oils, the double bond functionality in ordinary triglyceride oils can be epoxidized. When these oils are polymerized to form polyesters or polyurethanes in the presence of polystyrene to synthesize interpenetrating polymer networks (IPN), a new class of tough plastics is formed.read more

TL;DR: In this article, the tensile and flexural properties of natural and synthetic fiber-reinforced composite materials are compared. And the results show that the properties exhibited by both the natural-and synthetic fiber reinforced composites can be combined through the production of hybrid composite materials.
