Epoxy polymers are widely used for structural applications. One challenge is the brittle nature of the material and there are many approaches to enhancing the toughness. Two such approaches are the addition of graphene nanoplatelets (GnP) and the addition of carboxyl-terminated butadiene- acrylonitrile (CTBN) rubber. However, both of these approaches have been documented to have impacts on other mechanical properties as well. The following data (extension and load) were generated in a series of tensile experiments. All samples failed during testing. The following sample dimensions were used in the test: Sample Width Sample Thickness 13mm 2mm Gauge Length 50mm Neat DGEBA DGEBA+ 3wt% GnP M25 DGEBA+ 6% CTBN Extension Extension Extension Load [N] Load [N] Load [N] (mm] (mm] [mm] 5 91 228 58 10 169 10 423 10 108 15 228 15 569 15 146 20 299 20 748 20 191 25 363 25 908 25 233 38 566 37.5 1414 38 362 50 715 50 1788 50 458 63 879 62.5 2198 63 563 75 1029 75 2571 75 658 88 1159 87.5 2896 88 742 100 1262 100 3155 100 808 113 1361 112.5 3403 113 871 125 1438 125 3594 125 920 138 1495 137.5 3738 138 957 150 1553 150 3881 150 994 175 1633 175 1045 200 1675 200 1072 225 1698 225 1086 250 1698 250 1086 275 1698 275 1086 300 1077 325 1060 338 1040 350 1023 375 982 400 949 Using this tensile data, answer the following questions by developing MATLAB m-files.
