“…However, this failure mode was relatively rarely observed. Most of samples showed large plastic deformation with or without a small drop of stress after the elastic region (see Figure 13B) which can reveal the presence of crack propagation (van Rijswijk et al, 2009;Vieille et al, 2011;See et al, 2015;Obande et al, 2019). According to these results the failure mode cannot be directly related with the pressure level of the consolidation.…”

The main objectives of this article were to examine the feasibility of high quality laminate (carbon PEKK-Poly-Ether-Ketone-Ketone) manufacturing under low pressure and to analyze the principal phenomena governing the consolidation quality. The quality of laminate was evaluated in terms of the interlaminar shear strength measured by short-beam shear test and the residual voids observed by micrographic images. This work underlined the possibility to obtain a good interlaminar consolidation quality, i.e., interlaminar shear strength of 100 MPa under a low pressure of 7.0 × 10 4 Pa even for prepregs which were not designed for out-of-autoclave processes. To better understand the interlaminar consolidation phenomena, we developed an experimental setup for the in-situ monitoring of the laminate consolidation to measure the change of laminate thickness and the temperature gradient in the thickness direction during the manufacturing process. In particular, we identified two major phenomena, the establishment of intimate contact between the adjacent layers at the glass transition temperature and the molten matrix flow at the melting temperature. The assumption on the intimate contact establishment at the glass transition temperature was confirmed by the heat transfer simulation considering the change of thermal contact resistance at the interlaminar interface.

“…The DIC approach reveals the strain measurement on the specimens to restrict only in the region around the machined holes during the tensile test. 14 The failure characteristics of CFRP were also examined during the tensile test using a thin PZT piezoelectric ceramic plate, φ 9.0 × 0.12( t ) mm, which attached on the specimen directly. Concept of this approach is related to the acoustic emission method for detection of the localized failure.…”

The effects of machined circular holes on the mechanical properties and failure characteristics of a unidirectional CFRP were investigated. Our approach was to change the location and the number of holes: (i) a two-set hole was machined with different modes: (A) parallel, (B) 45°and (C) a direction perpendicular to the loading direction; and (ii) multiple holes from n = 0 to 5 were made in the sample parallel to the loading direction. The higher tensile and higher fatigue strengths were obtained for the CFRP sample produced by mode A, compared to modes B and C. This was attributed to the different extend of the maximum stress and stress distribution, caused by the geometrical effects on the sample. The ultimate tensile strength (σUTS) of the sample was well predicted by the geometrical criterion. If the number of holes was increased from n = 0 to n = 2, the tensile strength decreased dramatically. However, the tensile strength did not strongly decrease further for samples with multiple holes from n = 2 to 5. The tensile strength is correlated with the maximum stress adjacent to the hole(s). Those stress values were verified by a 2D digital image correlation and a finite element analysis. Material failure of the CFRP during tensile loading was revealed by nondestructive testing using a piezoelectric ceramic, and debonding of the fibers occurred even at a low applied stress of approximately 35% σUTS.

“…They found that those nanoparticles showed great potential to improve the mechanical and tribological properties of conventional thermoplastic/CF composites for structural applications. Liu et al [26] explored the interfacial micromechanical performance of carbon fiber T (CF) reinforced polyphenylene sulfide (PPS) composites by micro-bond test and concluded the interfacial shear strength increased with increasing fiber embedded length below 0.02 mm/s and above 0.04 mm/ s. Vieille et al [27] investigated the influence of temperature on mechanical properties and behaviors of carbon fiber fabric reinforced polyphenylene sulfide (PPS) laminates subjected to different loadings and they exhibited that a temperature up to the glass transition temperature (T g ) softens the matrix behavior and reduces mechanical properties (in-plane shear, compressive, flexural and interlaminar shear).…”

In this paper, two kinds of PPS/GF composite samples (PPS-0°, PPS-90°) were prepared with two different fiber main orientations related to the injection direction. A wide range of their properties were discussed. Using DMTA analysis, it was shown that the PPS/GF composite under study obeyed the time-temperature equivalence principle. Moreover, Perez model was verified and gave a good estimation of the viscoelastic properties of the PPS/ GF. Monotonic and fatigue behaviors and fatigue life of PPS/GF were investigated. Fiber's orientation, applied amplitude and loading frequency effects were emphasized. Self-heating effect on fatigue strength was also analyzed. SEM fracture surface observations allowed analyzing, at the local scale, the main deformation mechanisms occurring during mechanical loading. No evident damage development was observed for both monotonic and fatigue loading. PPS matrix plasticity appeared to be the predominant deformation mechanism until a semi-ductile or semi-brittle final failure depending on the loading conditions and local microstructure.
