A method has been developed for the quantitative determination of the composition of thermoplastic wood composites. The method involves area measurements of the two peaks in the derivative curve of a tracing produced by the thermogravimetric analysis (TGA) of a thermoplastic composites sample in an inert atmosphere. This may involve the standard, constant(More)
A complete sample preparation procedure used to determine three-dimensional fiber orientation from optical micrographs of glass fiber-reinforced thermoplastic composites is presented. Considerations for elimination of irregularities in the elliptical footprints, contrast enhancement between fibers and surrounding polymer matrix, controlled-etching that(More)
Wood-based composites such as plywood and oriented strand board (OSB) are commonly used for home manufacturing, therefore the bond performance between the resin and wood is critical. Wetting is often used to determine adhesive compatibility for wood-based composites. To give a more conclusive understanding of adhesive wetting, this research compared the(More)
Hemlock woolly adelgid (Adelges tsugae) is an invasive insect that is defoliating and killing eastern hemlock (Tsuga canadensis) in the USA. We quantified changes in tree-ring growth rates and wood anatomy for living trees infested with hemlock woolly adelgid across six sites from Massachusetts (42°41′N) to Georgia (34°53′N) to identify growth responses of(More)
Short and long fiber reinforced thermoplastics are a feasible alternative to develop lightweight materials for semi-structural and structural applications, respectively. These composites present a layered structure showing a complex tridimensional structure along the molding, created during the forming stage. The details of short fiber orientation in a(More)
Experimental results for the fracture behavior under mixedmode in-plane loading conditions of adhesively bonded wood specimens are reported. The material systems considered involved yellow-poplar ( Liriodendron tulipifera ), a hardwood of the Magnoliaceae family, as adherends bonded with two different adhesives, a moisture-cure polyurethane (PU) and a(More)
