Abstract. In this Big Data era, all the scientific research areas be needed by analyzing and mining knowledge from large-scale data sets. Mechanical Property of Composite Material is increasingly being used to improve our industrial product but how to get the advantages and challenges derived from Big Data is important part in vast amount of Composite Material data. Map-Reduce as an open source implementation would be a high reliability, high fault tolerance capability of parallel computing software framework. Map-Reduce based applications can be run in large clusters of parallel processing large data sets. this paper discusses the definition Mechanical Property of Composite Materials research by the parallel processing of Map-Reduce model. The performance this model of new material was established by using the method of Map-Reduction provided the basis for the performance optimization.
