316L stainless steel fatigue samples produced by laser powder bed fusion (L-PBF) process were stress relieved at 900 °C for 2 h to understand the effect of residual stress on fatigue strength. Two groups of fatigue samples were produced: “polished” and “machined and polished”. “Polished” samples were built to final fatigue sample geometry and then polished to avoid surface roughness effect while preserving the residual stress at the surface. The machined and polished samples were built to rod sh...

Abstract Fatigue characterization of injection moulded carbon fibre is conducted on specimens from ten locations on a flat plaque and two locations from an automotive oil pan. Fatigue testing was carried out using tension-tension and fully reversed loading at room temperature and 120° C using the specimens from the flat plaques. The stiffness and microstructure of the ten locations are used to calibrate a micromechanics model to evaluate the maximum interface stress for the stresses applied duri...

Abstract This study focuses on the notch effect on the fatigue failure of chopped carbon fiber chip-reinforced sheet molding compound (SMC) composites by using both experimental and numerical methods. The S-N diagrams of notched specimens are first obtained experimentally, which exhibit large scatter and are shown to depend on the spatial distribution of local fiber orientations. After considering the effect of this spatial distribution by adopting a new fatigue damage parameter to normalize the...

The fatigue behaviour of a biaxial carbon/epoxy Non-Crimp-Fabric (NCF) composite is evaluated at room temperature and 130o C for automotive applications. A new specimen geometry is developed allowing three stress ratios R = 0.1, R = −1 and R = 10 to be tested at 130o C without the use of anti-buckling fixtures for axial loadings. The three stress ratios show good agreement in fatigue life using an equivalent stress amplitude. The fracture surfaces from failed fatigue test specimens are compared ...

Abstract The material behavior of chopped carbon fiber chip-reinforced Sheet Molding Compound (SMC) composite is investigated under both quasi-static and cyclic fatigue loading conditions in the present study. Quasi-static tensile and compressive strength data is collected, followed by a series of fatigue tests under three different cyclic loading conditions, i.e., Tension-Tension (T-T), Compression-Compression (C-C), and Tension-Compression (T-C). The experimental results show a considerable am...

Abstract In present study, the fatigue damage behavior of chopped carbon fiber chip-reinforced composite has been experimentally and numerically investigated. A large scatter is exhibited in the S-N diagram due to the random distribution of carbon fiber chips, and therefore a new analysis procedure is proposed to link the local microstructure to the fatigue behavior of the bulk material. Interrupted fatigue tests are also performed so that microstructure characterization can be conducted on the ...

Abstract Fatigue tests for unidirectional (UD) CFRP composite specimens of various sizes are conducted under different stress ratios. The results show that the specimen size has considerable influence on the transverse tension-tension fatigue performance of UD laminates. The underlying fatigue mechanisms are also investigated through SEM observations. Moreover, a fatigue life prediction method considering size effects is presented, and a good correlation is observed between the prediction and th...
