Using the properties of the individual laminae as input variables, the laminate’s elastic modulus, axial strain, and lateral strain were determined by means of the model, and compared with values determined experimentally. The model yielded an axial elastic modulus of 950 MPa, which did not differ substantially from the measured value of 920 MPa. Statistical analyses showed that the measured and calculated strains were not significantly different in either the axial or lateral directions. The model underpredicted the strains along the fiber direction of the bicomponent fiber sheets by approximately 4%. A greater difference (12%) between predicted and measured values was observed in the lateral direction.}, number={3}, journal={BioResources}, author={Dyk, H. and Peralta, P. and PESZLEN, ILONA}, year={2013}, pages={3672–3684} } @article{arrieche_saloni_dyk_lemaster_2011, title={Evaluation of the Energy Balance for the Production of Briquettes from Biomass}, volume={61}, ISSN={["0015-7473"]}, DOI={10.13073/0015-7473-61.4.302}, abstractNote={Wood densification consists of processing wood by-products such as sawdust and chips into uniformly sized particles that are compressed into wood-based fuel products (pellets and briquettes). The main advantages are related to handling improvements of residual wood and energy generation opportunities when compared with wood chips from other forms of wood residues. The objective of this study was to evaluate the energy balance for production of briquettes from wood residues. This research involved determining the energy consumption required to perform the main manufacturing operations to produce wood briquettes: size reduction, drying, and densification of wood. The amount of energy that can be obtained from the combustion of wood briquettes was also measured. The effects of several factors such as wood species, material dimensions, and raw material moisture content on the energy requirements for manufacturing briquettes were studied. Four densification strategies were evaluated from an energy consumption ...}, number={4}, journal={FOREST PRODUCTS JOURNAL}, author={Arrieche, Rafael and Saloni, Daniel and Dyk, Herman and Lemaster, Richard L.}, year={2011}, pages={302–309} } @article{dyk_lemaster_2010, title={An Investigation of the Use of Active Infrared Thermography to Detect Localized Surface Anomalies in Lumber}, volume={32}, ISSN={["1932-8745"]}, DOI={10.1002/sca.20188}, abstractNote={Abstract}, number={4}, journal={SCANNING}, author={Dyk, Herman and Lemaster, Richard L.}, year={2010}, pages={219–223} } @article{dyk_peralta_peszlen_banks-lee_2009, title={An innovative wood-fiber composite incorporating nonwoven textile technologies}, volume={59}, DOI={10.13073/0015-7473-59.11.11}, abstractNote={This article is the first to describe a process of manufacturing engineered wood composites that combine two nonwoven textile technologies: bicomponent fiber and needle punching. Hardwood fiber was blended with 10 percent urea formaldehyde and formed into mats. The mats were sandwiched with polypropylene/polyester bicomponent fibers and then needle punched. Needle punching was done by means of barbed needles that oscillated in a vertical direction with regard to the surface of the fiber mat. The barbed needles mechanically interlaced the bicomponent web to the wood-fiber mat and pulled some of the polymer fibers through the thickness direction of the mat. During hot pressing, the polypropylene sheath of the bicomponent fiber flowed, bonded with adjacent wood fibers, and coalesced with the sheath of the adjacent bicomponent fibers. The mats were pressed until the urea formaldehyde was fully cured. Bending and tensile properties of the needle-punched wood composite were assessed and compared with medium-den...}, number={11-12}, journal={Forest Products Journal}, author={Dyk, H. and Peralta, P. and PESZLEN, ILONA and Banks-Lee, P.}, year={2009}, pages={11–17} } @article{pirraglia_saloni_dyk_2009, title={Status of lean manufacturing implementation on secondary wood industries including residential, cabinet, millwork, and panel markets}, volume={4}, number={4}, journal={BioResources}, author={Pirraglia, A. and Saloni, D. and Dyk, H.}, year={2009}, pages={1341–1358} }
