  • Developing New Routes for Mechanical Characterization of Metal-Organic Frameworks

    Creator:
    Maack, Bryan A.
    Abstract:
    Metal-organic frameworks (MOFs) represent an exciting, new class of porous materials. Their hybrid organic-inorganic structure opens up near infinite possibilities to tune and design their structure for specific properties and applications. A new generation of flexible MOFs, following a generation of stiff MOFs, has created additional design space and complexity....

  • An experimental study on tensile properties of cellulose nanocrystal reinforced epoxy nanocomposite material

    Creator:
    Zeng, Jin
    Abstract:
    Epoxy resin is a thermosetting resin that is commonly used as composite matrix. Epoxy composite materials are well utilized in industries, such as aerospace, due to their good mechanical properties. Nano-scale filler reinforced polymer composite materials have been intensively researched in recent decades. Cellulose nanocrystals (CNXLs) are a type of...

  • Heat treatment effects on CPM-M4 tool steel performance as edged blade material

    Creator:
    Lian, Sidi
    Abstract:
    CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...

  • Improving wood strength and stiffness through viscoelastic thermal compression

    Creator:
    O'Connor, John P.
    Abstract:
    The objective of this research project was to increase the density, strength, and stiffness of two low to medium-density diffuse-porous hardwood species. Wood used in this study was processed using a method of wood densification known as “Viscoelastic Thermal Compression” (VTC). The VTC process is a three phase treatment which...

  • Interfacial shear strength of wood-plastic composites

    Creator:
    Rogers, James F.
    Abstract:
    This study examined the relationship of interfacial shear strength (IFSS) and bending strength (MOR) of several different wood-plastic composites (WPC's). Plastics utilized were high-density polyethylene (HDPE) and polypropylene (PP). Pine and oak were used as the wood species. Compatibilizers used included maleicanhydride polyethylene (MAPE), polymeric methylene diphenyl diisocyanate (PMDI), KymeneTM,...

  • Study of Interphase in Polylactic Acid and Cellulose Nanocrystal Composite Films

    Creator:
    Rao, Pratish Ramesh
    Abstract:
    Polylactic acid (PLA), a renewable material, is used widely in a variety of commercial and specialty applications. However, certain limitations such as high temperature stability and brittleness limit its applicability. This problem is addressed by reinforcing PLA with a variety of materials but the process gives rise to different issues...

  • An experimental approach to analyze large notched composite panels loaded in out-of-plane shear

    Creator:
    Froemming, Tyler M.
    Abstract:
    Identifying material characteristics of composites is important in designing any structural system. The aerospace industry relies on these material properties not only to design a functional aircraft, but also a safe and reliable one. Since carbon fiber composites are relatively new materials, little is known about its characteristics under certain...

  • Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

    Creator:
    Sutton, Matthew T.
    Abstract:
    Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

  • Copper compounds for durable composites : effects on material properties

    Creator:
    Vidrine, Cheney L.
    Abstract:
    The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...
