Bisphenol-A based benzoxazine (Bz) was blended with di- and tri-functional epoxies to reduce viscosity for processing, and their resulting thermal and mechanical properties were characterized. Additionally, the formation of inter-molecular and intra-molecular hydrogen bonds was investigated within a Bz-epoxy two component system. Activation energy, heat of reaction, degradation temperature, hydrogen bonding characterization and thermo-mechanical characterization were studied using a differential scanning calorimeter, dynamic mechanical analyzer, thermogravimetric analysis, fourier transform infrared spectroscopy and Instron. Preliminary results show an unexpected synergistic increase in Tg of the blends, for both di- and tri-funcitonal epoxy blends. Surprisingly, while the two components exhibit Tg\u0026rsquo;s of ~ 150-170 \u003Csup\u003Eo\u003C\/sup\u003EC, the blended systems consistently exhibited a Tg in the range of 210-250 \u003Csup\u003Eo\u003C\/sup\u003EC. This work aims to reproduce thermal characterization data for the benzoxazine \u0026ndash; di-functional epoxy system, as well as explore a new benzoxazine \u0026ndash; tri-functional epoxy based system. Our underlying motivation in this study is to identify the origins of the synergistic increase in Tg upon blending through various thermo-mechanical characterization methods and in-situ FT-IR analysis of curing kinetics.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Development of Fundamental Understanding of the Cure Kinetics of Benzoxazine Epoxy Blends"}],"uid":"27707","created_gmt":"2019-12-13 19:11:33","changed_gmt":"2019-12-13 19:11:33","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-01-06T10:00:00-05:00","event_time_end":"2020-01-06T12:00:00-05:00","event_time_end_last":"2020-01-06T12:00:00-05:00","gmt_time_start":"2020-01-06 15:00:00","gmt_time_end":"2020-01-06 17:00:00","gmt_time_end_last":"2020-01-06 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
