Mechanical and thermal properties optimization of a synthetic agglomerate by using the Taguchi Method

In this work, the Taguchi Experimental Design model was applied for the optimization of the mechanical and thermal properties of an agglomerated composite material and to obtain the most appropriate parameters for its elaboration. The importance of the development of synthetic agglomerates is in the use of agricultural waste to give it a useful use when supplying high demand materials. Rice husk, clay, sand and aloe gel were used as raw materials. With the variation of the values ​​of the control factors: percentage of rice husk (R), temperature (T) and time of heat treatment (t), the different experimental combinations were performed. For the optimization of the mechanical and thermal properties according to the Taguchi methodology, the mechanical and thermal tests were selected: the modulus of elasticity, the energy absorbed in the impact, the modulus of maximum breakage and the initial decomposition temperature for each combination chipboard experimental. For the processing of this data, the software for the automatic design and analysis of Taguchi experiments, Qualitek-4, was used under the characteristic of higher-better quality. The optimal parameters obtained for each level of control were R = 15%, T = 120 C and t = 3 h. These results were validated with the performance of a confirmatory experiment, where properties similar to those of wood species were obtained for this agglomerate. The development of this prototype of alternative material will be useful as a substitute for wood and will contribute to the reduction of the environmental impact generated by waste products.
