Metodología experimental para determinar los parámetros del proceso de moldeo por compresión de materiales compuestos de termoplástico reciclado y madera recuperada

The objective of this research is to determine the sintering process parameters of wood-plastic composite materials (WPC) manufactured by compression molding and with better properties from an engineering point of view. The structure of this article is, by itself, a proposal of experimental methodology to obtain WPC from recycled thermoplastic particles and recovered wood. This methodology includes the characterization of both starting materials and compression-molding tests, to determine in a first stage the temperature and time of sintering and, in a second stage, the content and size of the wood particles. Using recovered capirona wood (RCW) and recycled polypropylene (RPP); these parameters are evaluated by standardized tests on molded samples. For this case, the parameters are: 50 min of time into the oven at 190 °C, 30% and 70% in volume of RCW and RPP respectively and RCW particles from 0,98 mm to 1,90 mm of size.
