non-biodegradable. It is speculated that enhanced with wood powder is a viable alternative in the production of new materials, which retain the characteristics thermal and of biodegradability morphological and possessing characteristics with gains mechanical in relation properties, to starting materials. This study aimed to develop a composite, and to obtain specimens through the process of injection / extrusion, formed by PHB, PCL and wood powder different concentrations.…

2008 Received in revised form 20 April 2009 Accepted 27 April 2009 Available online 28 May 2009 Keywords: Adhesion Polymer Thermodynamic Diffusion Molecular bonding Plasma Blends abstract Most industrially applied polymer resins and composites have low surface free energy and lack polar functional groups on their surface, resulting in inherently poor adhesion properties. A strong research momentum to understand polymer adhesion in the last decade has been motivated by…

madeira natural, para a fabricação de deques e cercas. Esses materiais foram denominados madeira plástica reciclada (RPL), cuja sigla origina-se do inglês recycled plastic lumber. Fabricavam-se tais perfis de plásticos reciclados ou a partir de composições com fibras de madeira (WPC), cuja sigla provém do inglês wood polymer composites. A expressão madeira plástica, segundo a American Society for Testing and Materials (ASTM), se aplica aos produtos manufaturados com conteúdo de plástico…

thermodynamic mechanical analysis. The thermal treatment (annealing) performed after the manufacture of the ethermoplastic starch reinforced plates allowed the materials to develop certain rigidity and higher mechanical strength compared to the untreated composites that were flexible and less tensile strength. The addition of fibers in the matrix of the thermoplastic starch resulted in decreased absorption of water, reduced value of the equilibrium moisture content, increased relative…

madeira, o que acabou incentivando a busca de alternativas para reaproveitamento desses resíduos. Nesses países, a escassez de madeira também tem provocado o aparecimento de produtos conhecidos como compósitos termoplásticos com madeira ou wood-plastic composites, WPC. Esses produtos têm encontrado grande aceitação no mercado em aplicações como perfis para construção civil e como componentes automobilísticos graças a sua leveza, versatilidade e baixo custo, quando comparados com a…
