A delamination or an interlaminar failure is a critical failure mechanism for fibrereinforced composites and, therefore, has already been studied extensively by many researchers. However, it remains an actual research topic, since every day, new polymers with better mechanical properties are being developed for fibre reinforced composites. This manuscript describes an experimental study of both the Mode I and Mode II interlaminar behaviour of a 5-harness satin weave carbon fabric reinforced polyphenylene sulphide (PPS). The mode I crack growth is studied using the Double Cantilever Beam (DCB) setup, whereas the mode II behaviour was studied by the End Notch Flexure (ENF) test. For mode I, an unstable crack-growth was seen resulting in a saw-tooth like force-displacement curve. Therefore, a model based on Linear Elastic Fracture Mechanics was considered to determine G IC for both initiation and propagation. Furthermore, the effect of possible fibre-bridging was assessed and an online microscopic study was conducted so that the origin of the specific jumps in crack growth could be determined. For mode II, stable crack propagation occurred and the Compliance-Based Beam Method was used to determine G IIC for both initiation and propagation. It could be concluded that the considered approach worked well for this material and reproducible results and values were found.

“…Modifying this parameter has been shown [1,17,16] to not significantly alter the overall mechanical response, since the dissipative process is mainly governed by the fracture energy. At time t nd , the initial cable lengths are zero and the directional cohesive elements are assumed to transmit a cohesive traction directed as the normal m k to the opening element side at the k-th integration point and of magnitude T 0 k , being T 0 k the maximum tensile stress at point k ( figure 3).…”

“…The adaptive definition of these latter parameters has also been proposed as a technique to improve accuracy in the presence of coarse finite element discretizations of the process zone [17,16]. In view of these considerations, a correction similar to the one proposed in [9,10] is considered in this work.…”

“…The cohesive zone method has been widely investigated for modelling composite delamination behaviour and was used for modelling fatigue delamination of composites [13], impact loading of UD laminate [14], compression after impact of UD laminate [15], soft impact of 3D woven composite [16], cantilever bending of 3D woven composites [17], and notched quasiisotropic laminate under tension [18]. Turon [19,20], Borg [21] and Harper [22] highlighted the sensitivity and the strategies in defining the cohesive properties.…”

Finite element simulation with cohesive contact is presented, to correlate the vacuum assisted RTM process and the bending performance of Omega beams. The model considers the process induced variations, including part thickness, resin rich pockets and voids. The bending performance prediction relies on cohesive contact to model delamination initiation and propagation. Computing efficiency is achieved by mesh scaling. The modelling approach applies to three variations of Omega beams with the different mode-mixture ratios.The finite element predictions result in a high degree of agreement with the experimental measurements.
