Abstract

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 of carefully ground and classified SYP bark as plywood adhesive fillers. Results can be used to select bark fractions having lower levels of ash. In addition, bark fractions rich in periderm tissue appear to perform better as plywood adhesive fillers relative to that prepared from whole bark.
