  • Defining Project‐Specific Custom CLT Grade Utilizing Low‐Value Ponderosa Pine Lumber from Logs Harvested in SW Oregon and Northern California Forest Restoration Programs

    Creator:
    Jahedi, Sina
    Abstract:
    Restoration programs effectively prevent or mitigate wildfires and pest outbreaks in the forest lands. The most common approach is to selectively harvest smaller and dead trees in order to preserve larger and superior trees. Ponderosa pine, Pinus ponderosa, (PP) lumber is one of the common species harvested from restoration programs...

  • Structural Design and Testing of Mass Timber Concrete Composite Floor Solutions with Acoustic Interlayers

    Creator:
    Srivastava, Mohit Raja
    Abstract:
    Timber-concrete composite (TCC) solutions originated in the early twentieth century. There has been a renewed interest in TCC solutions in modern mass timber buildings, especially for floor systems. However due to lack of data, design standards, and code acceptance, TCC solutions require that new mass timber solutions be tested, and...

  • Numerical Modeling of Mass Timber Connections

    Creator:
    Hollenbeck, Sean R.
    Abstract:
    Cross-Laminated Timber (CLT) is a prefabricated building material that is relatively new to the United States and North America. It consists of no less than three layers of graded, dimensional lumber glued in alternating longitudinal and transverse layers to create a panel that can be used for various building applications...

  • Investigation of Styrene-Free Unsaturated Polyester Resins for Fiber-Reinforced Composites

    Creator:
    Wu, Yili
    Abstract:
    Most of existing commercial unsaturated polyester (UPE) resins are typically composed of a UPE and a high amount of highly volatile, flammable, and toxic styrene. The emission of hazardous styrene in the handling of the UPE resins and the preparation and use of fiber-reinforced UPE composites poses severe hazards to...

  • Pressure sensitive adhesives based on oleic acid

    Creator:
    Wu, Yili
    Abstract:
    Existing pressure sensitive adhesives (PSAs) are mostly based on petrochemicals. In this study, a novel PSA based on a renewable material, methyl oleate, was prepared and characterized. Methyl oleate was first epoxidized to form epoxidized methyl oleate that was subsequently hydrolyzed and acidified to form epoxidized oleic acid (EOA) which...

  • Bending property enhancement of wood strand composite using viscoelastic thermal compression

    Creator:
    Rathi, Vardan M.
    Abstract:
    The fundamental intent of the study was to develop an innovative wood-strand composite for use in structural applications. Plantation grown, low density, hybrid poplar was used in the study which was found to be appropriate for the underlying Viscoelastic Thermal Compression (VTC) process. Wood modified by this process has high...

  • Analysis of adhesive atomization on composite bond performance

    Creator:
    Willard, Dylan T.
    Abstract:
    Spraying of liquid adhesive onto wood surfaces has shown to be a highly effective and efficient method of application across many different wood-based composite industries. However, the dynamics of spraying are extremely variable and distribution can be affected by liquid properties (rheology, molecular weight distribution, and temperature), application parameters (disk...

  • Effective Bonding Parameters for Hybrid Cross-Laminated Timber (CLT)

    Creator:
    Larkin, Blake
    Abstract:
    Cross-laminated timber (CLT) is a massive engineered wood product made of orthogonally bonded layers of solid-sawn lumber, and is intended for roof, floor, or wall applications. Although it was developed in Europe in the early 90s, CLT is relatively new to North America. CLT products must be certified for structural...

  • Characterization of load transfer in wood-based composites

    Creator:
    Schwarzkopf, Matthew John
    Abstract:
    The mechanical performance of composite materials is determined by the mechanical properties of their individual components and the effective load transfer between these components. Binders are commonly used to bond composite components together and to provide effective load transfer between them. In wood-based composites the binder-component load transfer occurs at...

  • Wood-adhesive bondline analyses with micro x-ray computed tomography

    Creator:
    Paris, Jesse Loren
    Abstract:
    There is no doubt that adhesive penetration plays an important role in wood bondline joint performance and durability; yet, to date there is no direct experimental evidence linking penetration depth with bond performance. This is, in part, because adhesive penetration is commonly assessed with various 2D microscopy techniques that are...
