Multi Criteria Decision Making Technique for Evaluation and Selection performance Large Scale Data of Composite Materials

the composite material is considered basic material in various fields nowadays. Many companies have produced different types of this product according to specific criteria. This paper aims to present a new methodology for evaluation and selection based on multi criteria decision making (MCDM) techniques. A novelty claims by using an evaluation matrix (EM) to evaluate sandwich composite materials performance. The main issue of the evaluation of sandwich composite materials is performed by finding suitable criteria for performance metrics and the trade-off among the different types of composite materials. The methodology implemented in two steps; 1) Creation decision matrix by calculating the data based on the five alternatives, 2) MCDM approach adapted by integrating between AHP and TOPSIS techniques. The finding outcome of the comparison of external with internal aggregation values to select the ideal sandwich composite materials was 5mm/5mm/5mm sample at 10J of threshold which is most recommended, whereas the 15mm sample at 25J of threshold obtained the lowest value, and it is the worst case.
