3. Bamboo particleboards: recent developments
RESUMO Devido à grande variação dimensional do bambu, a produção de materiais como compensados e laminados produz grande quantidade de resíduos. A produção de painéis particulados poderia ser utilizada para superar este problema e tornar-se uma solução viável na reutilização dos resíduos gerados como matéria-prima para produtos de alto valor

4. Paineis híbridos de lâminas e partículas de madeira para uso estrutural
Resumo O uso de painéis de madeira tem ganhado destaque na indústria da construção civil. Os painéis MDP não atingem requisitos estruturais, ao contrário dos painéis OSB e compensado. Uma alternativa a fim de aprimorar o uso de painéis de partículas de madeira consiste no reforço desses com lâminas de madeira (painéis híbridos). Esta pesquisa o

5. DISPLACEMENT MEASUREMENT IN SAWN WOOD AND WOOD PANEL BEAMS USING PARTICLE IMAGE VELOCIMETRY
ABSTRACT Throughout their useful life structures demand monitoring to verify their conditions of use. Thus, the need arises to seek methodologies capable to evaluate displacements and deformations in structural components of buildings. The objective of this research was to evaluate the use of the particle image velocimetry (PIV) technique to analyze test spe

7. ANALYSIS OF ELASTICITY IN WOODS SUBMITTED TO THE STATIC BENDING TEST USING THE PARTICLE IMAGE VELOCIMETRY (PIV) TECHNIQUE
ABSTRACT The most important parameter in terms of material mechanical behavior knowledge is the modulus of elasticity, being traditionally obtained through destructive tests. The objective of this study is the verification of the potential use of the particle image velocimetry technique (PIV) as a tool to obtain the modulus of elasticity in sawed wood sample
