  • Characterizing perpendicular-to-grain compression in wood construction applications

    Creator:
    Basta, Craig Thomas
    Abstract:
    Current compression perpendicular-to-grain (c-perp) design values for wood members are based on mean stress using the ASTM D143 specimen. Base design value, as determined from 0.04-in deformation in the ASTM specimen, is applied to all c-perp applications. While the standard ASTM test was presumably believed to adequately reflect relevant c-perp...

  • 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...

  • The phytosanitation of solid wood packaging materials using wood preservatives

    Creator:
    Schauwecker, Christoph F.
    Abstract:
    New species introductions have been associated with the movement of people for thousands of years. For instance, horses were introduced into North America by Spanish explorers, while pigs were introduced by the Polynesians into many Pacific islands long before the establishment of permanent European settlements. Both of these species introductions...

  • 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...

  • Evaluation of new formaldehyde-free, soy flour-based wood adhesives for making particleboard

    Creator:
    Gu, Kai
    Abstract:
    Formaldehyde-based adhesives such as urea-formaldehyde (UF), phenol-formaldehyde (PF) are widely applied in wood-based composite industry. However, these adhesives are all petrochemical-based and could not sustain in a long term due to a limited reserve of oil and natural gas. Moreover, these adhesives emit carcinogenic formaldehyde in the production or use...

  • 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...

  • Development of an Accelerated Method for Assessing Decay of Wood Plastic Composites (WPC's)

    Creator:
    Silva Guzman, Jose Antonio
    Abstract:
    This study examined the decay resistance of the pine and maple components of wood plastic composites (WPC' s) of varying thicknesses exposed on several culture media to wood decay fungi under laboratory conditions. The ability of malt agar extract (MEA), potato dextrose agar (PDA), amended basal salts, sawdust (maple and...

  • Development and evaluation of a new formaldehyde-free wood adhesive from renewable materials for making interior plywood

    Creator:
    Jang, Yonghwan
    Abstract:
    Synthetic adhesives, such as phenol-formaldehyde (PF) resins and urea-formaldehyde (UF) resins, have dominated the wood adhesive market since they were introduced in the wood products industry. Formaldehyde, as a key component in the manufacturing of PF and UF resins, has been classified as a known human carcinogen by the International...

  • Development and evaluation of oriented strandboard bonded with soy-based formaldehyde-free adhesives

    Creator:
    Schwarzkopf, Matthew John
    Abstract:
    Synthetic adhesives like phenol formaldehyde (PF) and isocyanates dominate the wood based structural panel market. The raw materials that makeup these adhesives are based on petroleum and natural gas. The sustainability and the continued success of the wood based structural panel industry will benefit from the development of alternative adhesives...

  • Determining fracture toughness by orthogonal cutting of polyethylene and wood-polyethylene composites

    Creator:
    Semrick, Kalin
    Abstract:
    The purpose of this thesis was to evaluate orthogonal cutting as a method to determine the fracture toughness of low and high density polyethylene and wood plastic composites. A test fixture was developed to capture normal and tangential cutting forces at variable depth and rake angle. A tool interface method...
