Resumen:
The purpose of this project has been to obtain new composites using filler and resin obtained from renewable resources, combining low cost and good mechanical properties. The matrix consisted in a polyester resin synthesized from linseed oil and further crosslinked with styrene in a peroxide initiated reaction Composite materials made from the unsaturated polyester/styrene thermoset and containing different percentages of woodflour were prepared and tested. The relationship between the filler content, porosity fraction and the mechanical properties of the materials were evaluated. The bending modulus and strength of the composites were significantly higher than that of the matrix. Simple models were successfully applied in the analysis of the mechanical properties of the materials. The porosity effect was also considered in the model predictions. The results of the mechanical and dynamic mechanical tests, the scanning electron micrographs of surface fractures and the adhesion parameter calculated from the strength models, agree in indicating that there is a strong interfacial interaction between matrix and filler.
