Abstract The objective of this research is to evaluate the possibility of use of tropical hardwood species (Amburana cearensis and Cedrella fissilis) for grilling plank production. Physical, chemical and organoleptic properties were evaluated and compared with properties of a well-used wood specie for grilling plank across Europe and USA, Western Red Cedar (Thuja plicata). For chemical analysis, three techniques were used: hydro distillation, soxhlet and head space. Normality test and analysis o...

Abstract Natural fibres have many advantages over synthetic ones, making them attractive for reinforcing polymer materials. This work evaluates the use of an Amazonian plant, namely Curaua (Ananas erectifolius), as a reinforcement phase of biocomposites fabricated by cold pressing. Curaua fibres have been shown to be a promising fibre for composite materials, especially due to their higher elastic modulus than other plant species. An L9 Taguchi design is used to investigate the effect of fibre f...

This study aimed to investigate the influence of moisture content variation on 12 mechanical properties of the Cedrelinga catenaeformis species. Of the 12 properties, four were significantly affected (based on analysis of variance at 5% significance level), and the compression and shear strengths in the direction parallel to the fibers exhibited the greatest difference in values from the saturated moisture condition of up to 12% (approximately 34% increase). Toughness exhibited a behavior differ...

Abstract This work describes the experimental and numerical behaviour of sandwich panels made of aluminium skins and bamboo core under low-velocity impact test. A statistical design is carried out to evaluate the effect of the bamboo diameter (O20 and O30 mm) and the adhesive type (epoxy and biopolymer) on the maximum load, energy to maximum load, total deflection and total energy of the panels, which are assessed through graphical and failure analysis. A non-linear finite element (FE) analysis ...

This work investigates a novel concept of sandwich panel composed of discarded polypropylene (PP) bottle caps as circular honeycomb core and skins made with a hybrid glass fibre/silica composite. A full factorial design (DoE) is carried out to identify the effects of the core packing system and the inclusion of silica particles in the composite skins, on the flexural properties of the sandwich panels. Finite element analysis validated by the experimental results is used to investigate and predic...

Por ser um material anisotropico e heterogeneo, o uso racional da madeira em estruturas requer o conhecimento de uma serie de propriedades fisicas e mecânicas. Parte das propriedades e obtida com o uso de equipamentos de grande porte, geralmente encontrados em poucos centros de pesquisas. A vibracao transversal consiste em um metodo de ensaio nao destrutivo utilizado na determinacao da rigidez da madeira, em funcao agilidade proporcionada na realizacao dos ensaios. Essa pesquisa objetivou, com b...
