The mechanical behavior of the panels was tested for perpendicular compression and tensile, longitudinal compression, three and four point bending, and shear. The load–displacement curves, patterns and cracking fractures were analyzed. The cork agglomerate provided a high performance under perpendicular compression, while the wood layers protected the core material and increased mechanical strength under tensile loads. Failure occurred mostly by fracture between cork granules. Multilayered sandwich panels showed higher strength and an increased number of layers improved the mechanical performance of the composite structure. The results suggested that these sandwich panels may be used as construction materials for paneling or partition walls in interior applications with the advantage of environmental friendliness and cost effectiveness.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pereira, H</style></author><author><style face="normal" font="default" size="100%">Baptista, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of raw-material quality and process parameters in the production of insulation cork agglomerates</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Wood and Wood Products</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemical composition</style></keyword><keyword><style  face="normal" font="default" size="100%">CORK AGGLOMERATES</style></keyword><keyword><style  face="normal" font="default" size="100%">Raw materials</style></keyword><keyword><style  face="normal" font="default" size="100%">structure</style></keyword><keyword><style  face="normal" font="default" size="100%">trituration behaviour (Voyant)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1993</style></year></dates><volume><style face="normal" font="default" size="100%">51</style></volume><pages><style face="normal" font="default" size="100%">301-308</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">{Insulation cork agglomerates are produced with different low-cost raw-materials unsuitable for other products: virgin corks (from prunmgs, thinnings anti dead trees), reproduction corks (refuse and underaged) and industrial byproducts (corkback strips).

The ability of adhesives to form good joints depends, among other factors, on the wetting of cork by the adhesives. The main objective of this research was to study the behaviour of adhesive drops deposited on cork substrates through measurements of contact angles and their time dependence. Several polyurethane prepolymers were tested to establish a correlation between the wetting characteristics and the chemical structure and physical properties of the adhesives. The effect of the morphology of cork on the interfacial properties was also investigated. The initial contact angles were related to the chemical nature of the adhesive. The kinetics of the wetting process were found to depend mainly on the viscosity of the adhesive.</style></abstract></record></records></xml>
