“…It is not usually desirable to use a material that experiences rapid changes caused by moisture, because moisture affects the physical and mechanical properties of woody materials. Shrinkage is approximately proportional to the amount of water lost from the cell wall [3].…”

Original scientific paper In this study, the aging period (20, 30, 40 and 50 days), the edge banding thickness (0,4; 0,8;1,0 and 2,0 mm) and the type of force used (bending strength-MOR and tensile strength-MOE) were the parameters selected for analysis of the effects on the mechanical properties of melamine coated particle board. To do this, Taguchi's methodology for the design of experiments was used to optimize the process parameters. Trials are conducted using an L16 orthogonal array with 16 combinations of test variables to assess the influence of various factors. Analysis of variance was also employed to investigate which design parameters significantly affect the mechanical properties of melamine coated particle board. The statistical analysis showed that the type of force used was the most significant factor affecting the response. The simulated and experimental results also showed good agreement with each other.

U tu svrhu, Taguchijevo oblikovanje metodologije pokusa provedeno je za optimizaciju procesnih parametara. Pokusi su provedeni po ortogonalnom polju L16 sa 16 kombinacija ispitnih varijabli za procjenu utjecaja različitih čimbenika. Analiza varijance također je bila uključena za istraživanje koji parametri konstrukcije značajno utječu na mehanička svojstva melaminom obložene iverice. Statistička je analiza pokazala da vrsta ostvarivanja sile krajnje promjenjivo djeluje na odziv. Simulirani i eksperimentalni rezultati također pokazuju dobro slaganje jednih s drugima.

“…In addition, a huge amount of planing waste (more than 65%) has been obtained during bamboo strip preparation for panel development (Zhang et al 2013;Sumardi et al 2007;Pannipa et al 2011). Many attempts have been undertaken to improve the utilization ratio of bamboo through reconstituting bamboo (Li et al 2007;Nugroho and Ando 2000;2001;Mhmad and Kamke 2005;, but the production of high-performance bamboobased panel is still impracticable due to the high resin addition and the free formaldehyde emission levels, and high capital requirements for facilities. Particleboard using thermopressing seems to be a viable alternative for the utilization of bamboo wastes.…”

A simple, practical, and low-technology approach was developed to fabricate corrugated bamboo particleboards (CBP), a novel bamboo product with a corrugated structure, from bamboo waste (planer waste). This product could be manufactured anywhere in the world where the bamboo industry develops. The selected mechanical and physical properties of CBP were prepared with urea formaldehyde resin at three press temperatures and two density levels and were evaluated. The results showed that the performance of CBPs is highly dependent upon the board density. The static bending strength of CBP laminated with MDF initially increases, and then decreases with increasing press temperature. Increasing the magnitude of the press temperature has a slightly positive effect on the thickness swelling and water absorption. Compared with the excellent mechanical strength of CBP (laminated with MDF), the thickness swelling value of this bamboo-based particleboard without any waterproofing treatment was lower than the minimal requirement of the EN standard.

“…Variações significativas das propriedades mecânicas de colmos de diferentes idades e avaliados em diferentes posições do colmo têm sido relatadas na literatura, relatando-se que as resistências à tração, compressão e flexão aumentam gradualmente com a idade e a altura (AHMAD, 2000). Apesar do relato de pesquisas bem sucedidas, tem sido reportado o inconveniente para se determinar as propriedades mecânicas dos colmos de bambu, porque não há padronização, e cada pesquisador adota uma metodologia diferenciada, o que torna difícil a comparação de resultados (BERNDSEN, 2008).…”

ResumoO objetivo deste estudo foi analisar o efeito da posição do colmo e da idade nas propriedades mecânicas de flexão estática e compressão paralela às fibras do bambu-mossô (Phyllostachys pubescens), correlacionando a densidade aparente com as propriedades avaliadas. Os corpos de prova utilizados nos ensaios foram produzidos de material laminado colado, adaptados segundo a norma para madeira sólida ASTM D143-96, seguindo as proporções mantidas por Ahmad (2000). Os resultados apresentaram tendência crescente da resistência na flexão estática com a idade e com a posição do colmo em termos absolutos. Para os ensaios de compressão paralela às fibras, a resistência à compressão (fc) e o MOE tiveram a mesma tendência de aumento da resistência com a idade e com a posição. Os ensaios demonstraram estatisticamente que não houve efeito significativo da interação entre a idade e a posição do colmo. A densidade aparente apresentou uma correlação linear e positiva no teste de flexão estática quanto aos valores do MOR e do MOE, assim como no teste de compressão paralela às fibras para a resistência à compressão (fc) e para o MOE. Baixos coeficientes de correlação foram obtidos entre a densidade aparente e as propriedades mecânicas estudadas. Palavras-chave: Propriedades mecânicas; idade; posição no colmo. Abstract Compressive strength and flexure of Moso bamboo (Phyllostachys pubescens).The aim of this study was to determine the mechanical properties of bending and compression parallel to grain of Moso bamboo (Phyllostachys pubescens) and analyze the effect of stem position and age on these properties. It was also studied the correlation between the bulk density and mechanical properties. The tests used specimens produced in glued laminated material, adapted according to ASTM D143 solid wood-96 norm, following proportions maintained by Ahmad (2000). The results revealed increasing trend of resistance in bending with age and stem position in absolute terms. In relation to compression tests parallel to grain, the compression strength (fc) and the MOE had the same tendency to increase resistance with age and with the position. The tests revealed that there was no statistically significant interaction between age and culm position. The apparent density of bamboo revealed a positive and linear correlation in bending test at MOR and MOE, as well as at parallel compression test to the fibers for the compression force (fc) and the MOE. Low correlation coefficients had been obtained between the focused apparent density and mechanical properties.
