Abstract
The purpose of the study is to access the applicability
of full factorial experimental design in predicting mechanical properties of polypropylene based composites. The
polypropylene based composites reinforced with kenaf fibers
were manufactured by melt mixing and consequently compression molded. For all manufactured composites the
tensile and flexural strengths were determined. The preparation of the composites was conducted by applying 22 full factorial experimental design. The fiber/resin ratio was taken to be the first factor and the second – mixing temperature. For the first factor, low and high levels are chosen to be 20/80 and 40/60, respectively and for the second factor – 175oC and 195oC, respectively. Based on the experimental data, the regression equations were obtained which best describes the influence of the chosen factors on the mechanical properties of the composites. The first-order linear model to approximate the response, i.e. the flexural and tensile strength and modulus of the composites within the study domain (20/80 – 40/60) ratio x(175-195) oC was used. The influence of each individual factor to the response function is established, as well as the interaction of both factors. It was found that the estimated first-order regression equation with interaction gives a very good approximation of the experimental results of the mechanical properties of composites within the study domain. The polypropylene based composites exhibit good
characteristics for application as construction materials for housing systems.
