Carbon-fiber-reinforced epoxy-matrix composite (CFRP) laminates with thin plies have strong damage-resistance properties compared with standard prepregs. The static and fatigue tensile fracture behavior of cross-ply CFRP laminates with thin plies should be further studied to establish the applicability of thin-ply prepregs for industrial structures. In this study, the static and fatigue tensile properties of cross-ply, high-strength polyacrylonitrile (PAN)-based carbon-fiber (T800SC)-reinforced epoxy-matrix composites with thin plies were investigated. The fiber orientations of the CFRP specimens were set to cross-ply with [0/90]10S (subscript S means symmetry), [(0)5/(90)5]2S, and [(0)10/(90)10]S. The static and fatigue tensile characteristics of the cross-ply CFRPs with thick plies with [0/90]2S and [(0)2/(90)2]S were also investigated for comparison. Under static loading, the tensile strength and failure strain of the thinnest 90°-ply-CFRP specimens were more than 5% higher than those of the other 90°-ply-thickness specimens. However, the tensile moduli and Poisson’s ratios were comparable between the cross-ply CFRPs with thin and thick plies. Under fatigue loading, the fatigue responses of the thinnest 90°-ply-CFRP specimens were 3% higher than those of the other 90°-ply-thickness specimens during lower-fatigue-cycle testing (<105 cycles). However, during higher-fatigue-cycle testing (>105 cycles), the fatigue responses decreased, with a decrease in the 90°-ply thickness, and the fatigue characteristics of the thinnest 90°-ply-CFRP specimen were 7% lower than those of the other cross-ply thin- and thick-ply-CFRP specimens.

“…The analysis of hysteresis loops is an important method for studying the fatigue damage mechanisms as reported by Naito et al 35 Therefore, the stress‐local strain curves were recorded periodically at different intervals depending on the length of the tests using WaveMatrix software. The last 50‐cycles were recorded even if test stops unexpectedly.…”

Scarf adhesive joints (SAJs) in carbon fiber composites were fabricated with 5° taper angle and bondline thickness of 0.17 mm. The joints are modified with SiC‐nanoparticles and characterized through tensile and fatigue loading at room temperature (RT) and 50°C. The analysis of the hysteresis loop in terms of loss and storage moduli, potential and dissipated energies, and damping factor is a quite new topic and one of the important goals of this study. At RT, the fatigue limit of the SAJs was improved by 55% when the bondline thickness decreased from 0.25 to 0.17 mm and further enhanced by 22% with SiC incorporation. For the first time, the evolution of the potential energy versus fatigue cycles of the SAJs can be modeled for early predicting joint life and hence helps in preventing their sudden failure. At 50°C, the fatigue strength of the SiC‐SAJ is approximately equal to the unmodified joint at RT.
