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 Gauge Length 13mm 2mm 50mm 15 DGEBA+ 3wt% GnP M25 Extension Load [N] [mm] 0 0 5 228 10 423 15 569 20 748 25 908 37.5 1414 50 1788 62.5 2198 2571 87.5 2896 100 3155 112.5 3403 125 3594 137.5 3738 150 3881 Neat DGEBA Extension Load [N] [mm] 0 0 5 91 10 169 228 20 299 25 363 38 566 50 715 879 1029 88 1159 100 1262 113 1361 125 1438 138 1495 150 1553 175 1633 200 1675 225 1698 250 1698 275 1698 63 75 75 DGEBA+ 6% CTBN Extension Load [N] [mm] 0 0 5 58 10 108 15 146 20 191 25 233 38 362 50 458 63 563 75 658 88 742 100 808 113 871 125 920 138 957 150 994 175 1045 200 1072 225 1086 250 1086 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.
