  • 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...

  • 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...

  • Development of formaldehyde-free wood adhesives

    Creator:
    Peshkova, Svetlana
    Abstract:
    Wood adhesives are essential components of wood composites. At present, the commonly used wood adhesives, phenol-formaldehyde (PF) and urea-formaldehyde (UF) resins, are petroleum-based synthetic resins that may result in emission of formaldehyde in the production and use of wood composites. Because the world's oil reserves are naturally limited and formaldehyde...

  • Multi-scale Investigation of Adhesive Bond Durability

    Creator:
    McKinley, Paige Elizabeth
    Abstract:
    Moisture durability is essential for wood composites, especially those used in building construction, where products are prone to weathering. The primary focus of this research was to determine if adhesive penetration into the cell wall has a positive influence on adhesive bond durability. To fully understand the measureable effects of...

  • Development and characterization of new formaldehyde-free soy flour-based adhesives for making interior plywood

    Creator:
    Huang, Jian
    Abstract:
    Formaldehyde-based adhesives such as urea-formaldehyde (UF) and phenol-formaldehyde (PF) adhesives dominate the current wood adhesive market. However, these adhesives are derived from petrochemicals and carcinogenic formaldehyde. In this study, we developed two formaldehyde-free adhesives based on abundant, renewable, and inexpensive soy flour (SF). The first adhesive was mainly composed of...
