Thermal conductivity of the composites decreases on addition of vermiculite aspore-maker. Physical and mechanical properties of the composites are improved by incorporating pol-ypropylene fibers. A nonlinear finite element model of a three point bending model and a design of experiments analysis have been developed to evaluate and optimize the additive concentrations and also to understand the effects provided by the additives on the mechanical strength. Statistical response surface method with three-level factorial was employed to evaluate the effect of addition of vermiculite and polypropylene fibers on gypsum composites. Our methodology can be applied to other nonlinear materials for property optimization. | URI: | http://ri.uaemex.mx/handle20.500.11799/79894 | Other Identifiers: | http://hdl.handle.net/20.500.11799/79894 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
