Patent number: 9884944Abstract: Functionalized polymer matrix and/or reinforcement materials that are capable of a thermoreversible Diels-Alder reaction are useful for making composite materials. Also disclosed is a composite material which includes one or both of functionalized reinforcement materials and functionalized polymer matrix materials, as well as a method for repairing a composite material including the step of thermally treating the composite material at a temperature sufficient to react a functionality on one of the reinforcement material and the polymer matrix material with another functionality via a Diels-Alder reaction. A method of making a composite material including functionalizing one or both of a reinforcing material and a polymer matrix material with a first reactive group, providing a second reactive group capable of undergoing a Diels-Alder reaction with the first reactive group and reacting the first and second reactive groups to form a composite material, is also described.Type: GrantFiled: May 18, 2011Date of Patent: February 6, 2018Assignees: Drexel University, The United States of America as Represented by the Secretary of the ArmyInventors: Giuseppe R.

Publication number: 20170247499Abstract: Grafted triglycerides comprising a triglyceride grafted with a fatty acid residue containing 4 to 30 carbon atoms are reacted with an epoxide resin and an amine curing agent to yield an epoxy thermoset. The grafted triglyceride is prepared by reaction of an epoxidized triglyceride with a fatty acid. By varying the length of the fatty residue, the number of fatty residues per triglyceride, the identity of the epoxy resin and the amine curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride.Type: ApplicationFiled: September 11, 2015Publication date: August 31, 2017Applicants: Drexel University, United States Government as represented by the Secretary of the ArmyInventors: Giuseppe R.

Publication number: 20160075872Abstract: Grafted triglycerides prepared from an epoxidized triglyceride and an acid anhydride containing 4 to 40 carbon atoms are reacted with an epoxy resin and an anhydride curing agent to yield an epoxy thermoset. By varying the length of fatty residues on the grafted triglyceride, the number of fatty residues per triglyceride, the identity of the epoxy resin and the anhydride curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride. A significant improvement in fracture toughness with a minimal reduction of glass transition temperature may be thus achieved.Type: ApplicationFiled: September 10, 2015Publication date: March 17, 2016Applicant: DREXEL UNIVERSITYInventors: Giuseppe R.
