  1. Strategies for improving the performance of plywood adhesive mix fillers from southern yellow pine bark

    Southern yellow pine bark was obtained from an industrial source and subjected to grinding and classification operations to ultimately afford finely ground bark fractions for evaluation as plywood adhesive mix fillers. Specifically, by grinding in a laboratory blender, we were able to generate a bark fraction rich in periderm tissue with its interlocking spiculate...

  2. Grinding and classification of pine bark for use as plywood adhesive filler

    Prior efforts to incorporate bark or bark extracts into composites have met with only limited success because of poor performance relative to existing products and/or economic barriers stemming from high levels of processing. We are currently investigating applications for southern yellow pine (SYP) bark that require intermediate levels of processing, one being the use...

  3. Partitioning of pine bark components to obtain a value-added product for plywood manufacture

    Southern yellow pine (SYP) bark particles and bark extracts have been used only to a limited extent in wood-based composites due to poor performance relative to existing products and/or economic barriers. Our efforts to identify alternative applications for this biomass resource require the development of an improved understanding of the interrelationships between bark...

  4. Accelerated weathering of natural fiber-filled polyethylene composites

    The resistance of natural fiber-filled high-density polyethylene composite specimens to ultraviolet- (UV) and moisture-induced degradation was evaluated by measuring changes to flexural properties. High-density polyethylene (HDPE) served as the polymer matrix for four formulations: two formulations without fiber filler and two formulations one containing wood flour and...

  5. Accelerated weathering of natural fiber-thermoplastic composites : effects of ultraviolet exposure on bending strength and stiffness

    Mechanical properties of bending stiffness and yield stress were used to evaluate the effects of ultraviolet exposure on natural fiber-thermoplastic composites. Four different specimen formulations were evaluated. Injection molded high density polyethylene (HDPE) served as the polymer base for all formulations. Two lignocellulosic fillers, wood flour and kenaf fiber,...
