Such materials have been studied extensively for their bulk properties as well as the properties of their individual components.\u0026nbsp; However, there remains an intermediary lengthscale on the order of the arrangement of the reinforcing phase which has yet to be satisfactorily characterized.\u0026nbsp; Understanding the properties of this intermediary lengthscale is critical to the development of multi-scale models with predictive capabilities.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETo address this need, the use of instrumented indentation on a lengthscale appropriate to the material system presents itself as a viable solution.\u0026nbsp; Indentation is uniquely suited to such an implementation due to its inherent ability to conform to the lengthscale of testing needed and its high throughput nature.\u0026nbsp; Recent advancement in the data analysis protocols has allowed for the extraction of stress-strain curves from the load-displacement data resulting from indentation tests in a variety of materials including single and polycrystalline metals, natural materials and polymers.\u0026nbsp; The goal of this thesis is to extend these protocols to address the unique challenges presented by their application to polymer matrix composites.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFor this purpose, two disparate materials systems have been chosen to develop the protocols.\u0026nbsp; One is a laminate composite system made from carbon fibers embedded in an epoxy matrix.\u0026nbsp; Here the intrinsic variation within a single ply is tested within the laminate composite.\u0026nbsp; The second material system is a nano-composite composed of multi-walled carbon nanotubes (CNTs) in a polypropylene matrix.\u0026nbsp; Here the variability in properties due to the presence of agglomerates of the CNTs will be explored.\u0026nbsp; Application to these two differing material systems will demonstrate the applicability of these protocols for determining the properties of composites on the desired scale.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Mechanical Response of Polymer Matrix Composites Using Indentation Stress-Strain Protocols"}],"uid":"27707","created_gmt":"2018-10-11 15:40:32","changed_gmt":"2018-10-11 15:40:32","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-10-24T13:00:00-04:00","event_time_end":"2018-10-24T15:00:00-04:00","event_time_end_last":"2018-10-24T15:00:00-04:00","gmt_time_start":"2018-10-24 17:00:00","gmt_time_end":"2018-10-24 19:00:00","gmt_time_end_last":"2018-10-24 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"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":""}}}
