Miscanthus sinensis was pretreated and used to produce fiberboard with no synthetic binders. The lignocellulosic material was steam exploded with a thermomechanical aqueous vapor process in a batch reactor. The effect of the pretreatment and the pressing conditions on the physicomechanical responses of the fiberboard was evaluated and the conditions that(More)
A Miscanthus Sinensis plantation in Galicia, Spain, provided the raw material for experimental fiberboards. After harvesting, the Miscanthus stems were cleaned and chipped. The chips were steam exploded with a thermo-mechanical aqueous vapor process in a batch reactor. The resulting material was dried, slightly milled, and used to produce fiberboard with no(More)
was thermomechanically pretreated and used to produce fiberboard with no synthetic binders. The lignocellulosic material was steam exploded using an aqueous vapor process in a batch reactor. Part of the resultant pulp was ground to pass through a 4-mm sieve. The effect of the grinding on the physicomechanical responses of the fiberboard was evaluated. ANOVA(More)
Polymer layered silicate (PLS) nanocomposites have been prepared with diglycidyl ether of bisphenol-A (DGEBA) epoxy resin as the matrix and organically modified montmorillonite (MMT) as the clay nanofiller. Resin-clay mixtures with different clay contents (zero, two, five and 10 wt%) were cured, both isothermally and non-isothermally, using a(More)
The main objective of this study was to explore the suitability of Vitis vinifera as a raw material and alkaline lignin as a natural binder for fiberboard manufacturing. In the first step, Vitis vinifera was steamexploded through a thermo-mechanical vapor process in a batch reactor, and the obtained pulp was dried, ground, and pressed to produce the boards.(More)
An innovative blended-learning strategy is presented for the subject Laboratory of Elasticity and Strength of Materials, based on the use of different tools combining face-to-face methods with e-learning technologies to improve learning outcomes in Mechanical Engineering. The enhanced teaching environment includes upgraded teaching material, new(More)
Lignin was used as a natural adhesive to manufacture Vitis vinifera fiberboards. The fiberboards were produced at laboratory scale by adding powdered lignin to material that had previously been steamexploded under optimized pretreatment and pressing conditions. The kraft lignin used was washed several times with an acidic solution to eliminate any(More)
Multiarm star polymers, with a hyperbranched poly(ethyleneimine) (PEI) core and poly("-caprolactone) (PCL) arms end-capped with acetyl groups were synthesized by ring-opening polymerization of "-caprolactone from PEI cores of different molecular weight. These star polymers were used as toughening agents for epoxy/anhydride thermosets. The curing process was(More)
