Abstract Wood-based composites, such as oriented strand board, are typically manufactured by consolidating mats of resinated wood elements under heat and pressure. During this process, the temperature and moisture content distributions within the mat greatly affect the properties of end products. To improve the fundamental understanding of mat consolidation during hot-pressing, a model is established to investigate the transverse compression behavior of aspen wood strands for a variety of combinations of temperatures (20–200°C) and moisture contents (0–15%). A regression approach is used to obtain the modulus-temperature-moisture relationship. In addition, elevated temperatures and moistures are found to influence the strain function of wood strands, which was previously assumed to be independent of these factors.

ResumenEn numerosos detalles estructurales de construcciones realizadas con madera, el esfuerzo de compresión transversal a las fibras juega un papel muy importante y en muchas ocasiones condiciona su diseño. En este trabajo se analiza el comportamiento a compresión de piezas de madera de pino silvestre de pequeña escuadría sometidas a un esfuerzo de compresión transversal a las fibras y se han obtenido unos valores medios para la tensión de rotura y el módulo de elasticidad de 4,20 MPa y 305,86 MPa, respectivamente.AbstractIn many structural details of buildings made of wood, the transverse compression stress to the fibers plays a very important role and often determines its design. In this work, the compression behavior of small pine wood pieces subjected to a cross - compressive stress to the fibers is analyzed and mean values for the tensile strength and the modulus of elasticity of 4,20 MPa and 305.86 MPa, respectively.

Polarized infrared microscopy has been used for forensic purposes to differentiate among polymer fibers. Dichroism can be used to compare and discriminate between different polyester fibers, including those composed of polyethylene terephthalate that are frequently encountered during criminal casework. In the fiber manufacturering process, fibers are drawn to develop molecular orientation and crystallinity. Macromolecular chains are oriented with respect to the long axis of the fiber. It is desirable to determine the relationship between the molecular orientation and stretching properties. This is particularly useful on a single fiber basis. Polarized spectroscopic differences observed from a single fiber are proposed to reveal the extent of molecular orientation within that single fiber. In the work presented, we compared the dichroic ratio between unstretched and stretched polyester fibers, and the transition point between the two forms of the same fiber. These techniques were applied to different polyester fibers. A fiber stretching device was fabricated for use on the instrument (IRμs, Spectra-Tech) stage. Tension was applied with a micrometer screw until a “neck” was produced in the stretched fiber. Spectra were obtained from an area of 24×48 μm. A wire-grid polarizer was used between the source and the sample.
