CRUZ-SALGADO, Javier; ALONSO-ROMERO, Sergio; DOMINGUEZ-DOMINGUEZ, Jorge  and  ZITZUMBO-GUZMAN, Roberto. Optimization of the Tensile and Flexural Strength of a Wood-PET Composite. Ing. invest. y tecnol. [online]. 2015, vol.16, n.1, pp.105-112. ISSN 2594-0732.

The large amount of disposable bottles presently produced makes the search for alternative products that reuse these materials imperative. Wood-plastic composites are sustainable, organic materials, that show potential for the development of environmentally friendly products. This paper presents the optimization of tensile and flexural strength of a wood-plastic composite made ​​from polyethylene-terephthalate, as thermoplastic resin, and sawdust as fiberfill. The goal of this study was to establish the operating conditions that provide the optimum properties of the wood-plastic composites, with minimal variance. The particle size of the fiber filler was taken as a noise factor. The response surface methodology, by contour lines, in a combined design of experiment was applied.

Keywords : response surface methodology; wood-PET composites; tensile and flexural strength; polyethylene-terephthalate; robust design.
