Abstract

A high temperature damage tolerant epoxy resin system was modified with three types of nanoparticles: chemically modified montmorillonite (MMT) organodays, surface treated nanosilica, and surface modified carbon nanofibers (CNF) to create mew types of epoxy nanocomposites. Wide angle X-ray diffraction (WAXD) and transmission electron microscopy (TEM) were used to determine the degree of dispersion. Dynamic mechanical thermal analysis (DMTA) was used to determine the T g and complex modulus of the polymer nanocomposites. The TEM analyses indicated that the MMT clay, nanosilica, and CNF dispersed very well in the epoxy resin system. Evidence is presented that a nanophase is formed when nanoparticles such as surface treated clay, surface treated nanosilica, or carbon nanofibers are introduced into the epoxy resin. Higher T g and complex modulus values from DMTA for the nanomodified materials are presented as evidence for nanophase presence in the epoxy resin system as compared to lower T g and complex modulus for the epoxy resin control The DMTA data of the neat epoxy nanosilka nanocomposite (2% Aerosil® R202) show the highest T g (258°C) and the highest complex modulus (964 MPa). Five epoxy nanocomposites and a control were selected to produce prepregs using AS4-6K fabric, followed by fabrication into composite panels. The short beam shear values of all epoxy nanocomposites were slightly lower than the baseline with 3% Aerosil® R202 and 2% PR-19-PS-Ox CNF higher than the baseline. The flexural strength of all the epoxy nanocomposites were slightly lower than the baseline with the 2% Cloisite® 10A and 3% Aerosil® R202 materials higher than the baseline. Flatwise tension strength values of all the eposy nanocomposites were slightly lower than the baseline with 2% PR-19-PS-Ox and 2% Aerosil® R202 samples higher than the baseline material. The G 1c and G 2c values of all the epoxy nanocomposites were below the baseline with the least knockdown for 2% Aerosil® R805 (G 1c) and 2% PR-19-PS-Ox (G 2c) being higher than the baseline.
