  • Formaldehyde-free wood adhesives from soybean protein and lignin : development and characterization

    Creator:
    Liu, Yuan
    Abstract:
    Presently, the production of wood composites relies on the formaldehyde-based wood adhesives such as phenol-formaldehyde (PF) and urea-formaldehyde (UF). However, their dependence on exhaustible fossil fuels and the emission of carcinogenic formaldehyde prompt to develop an environmentally friendly adhesive from renewable natural resources. This work focuses on development and characterization...

  • 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 and evaluation of novel coupling agents for kenaf-fiber-reinforced unsaturated polyester composites

    Creator:
    Ren, Xiaofeng
    Abstract:
    Natural fibers are gaining popularity as reinforcement materials for thermoset resins over the last two decades. Natural fibers are inexpensive, abundant, renewable and environmentally friendly. Kenaf fibers are one of the natural fibers that can potentially be used for reinforcing unsaturated polyester (UPE). As a polymer matrix, UPE enjoys a...

  • Durability Assessment of Wood Composites Using Fracture Mechanics

    Creator:
    Mirzaei, Babak
    Abstract:
    The advent of synthetic adhesives has transformed the structural applications of wood. However, a persistent issue in adhesively-bonded wood products has been moisture durability. When designing wood based composites, moisture durability will depend on both the wood phase and the adhesive phase. A key question, therefore, is how does one...
