“…143,144 Scientists have studied the influence of fibre architecture on the fracture behaviour and strength reduction of laminates having holes or cracks. [181][182][183] The failure mechanism of laminates made from woven fabrics appeared slightly different from that found in composites made from UD tapes because of the yarn interlacement. Compared to UD tape laminates, the fabric laminates are more resistant to delamination and splitting, and prevent crack propagation in the matrix due to their undulating nature that hinders these damage mechanisms.…”

As the use of composite laminates are unceasingly increasing more and more in many applications, the in-depth understanding about the impact response of composite laminates in certain areas like sport, aerospace and automotive has gained more attention of the designers and scientists over the last two decades. The authors have focused to review the impact properties of fibre reinforced composites particularly impact damage tolerance. Impact resistance, damage tolerance, composite failure and methods of assessing damage tolerance are presented. Furthermore, the approaches for improving damage tolerance such as fibre architectures resin system, and hybridisation using either yarn hybridisation or hybrid layers are discussed. In the end, a survey of modelling the impact damage of laminated composites is made by considering the inter-laminar and intra-laminar failures as key point for evaluating the response of laminates under impact loading.

“…For example, for cross-ply plain E glass-epoxy composites, (Reis et al, 2012) pointed out that the Young's modulus is almost insensitive to strain rates for a fiber volume content of 47% and engineering strain rates between 1,6 10 1,6 10 , conversely to the strength, which is importantly influenced by the strain rate. In contrast, (Boey & Kwon, 2013) reported a relevant increment in the Young's modulus of the composite with the strain rate for nominal strain rates between 5 10 5 10 , using a bidirectional fiberglass E cloth with vinylester resin. The authors also reported an important increment in the strength when the strain rate is higher.…”

“…As it was aforementioned, many authors have studied the influence of the strain rate on the elastic modulus and tensile strength of woven composites (Boey & Kwon, 2013;O I Okoli & Smith, 2000;Reis et al, 2013Reis et al, , 2012. Some equations describing such relationship have been used by those authors.…”

“…One simple explanation of this phenomenon was exposed by (O I Okoli & Smith, 2000): when the strain rate increases, the strength and stiffness of the fibers also increase and the material tends to fail first by fiber pull out because the fiber-matrix interface strength is Latin American Journal of Solids and Structures 13 (2016) 344-364 exceeded before the ultimate tensile strength of the fiber is reached. Nevertheless, (Boey & Kwon, 2013)recently investigated the progressive failure of specimens under several strain rates by recording the tests and concluded that the failure started with matrix cracking and interfacial debonding, followed by fiber breakage, independently of the strain rate. On the other hand, the change of the size of the damaged region with the strain rate for unidirectional glass/epoxy composites was analyzed by (Shokrieh & Omidi, 2009) .…”

High performance composites are exposed to severe loading and environmental conditions. In this work, mechanical properties of Fiberglass Reinforced Polyester (FRP) manufactured by resin transfer molding were evaluated. The effect of the strain rate on mechanical properties under three quasi-static testing conditions, four fiber contents and several orientations was studied using instrumented tensile tests. A model was fitted to predict Tensile strength, Young's modulus and shear modulus and the failed samples were analyzed to understand the failure mechanisms. The results showed that the fitted model is reliable enough to conclude about the effect of the fiber volume fraction and the strain rate on the mechanical properties. Young's modulus and tensile strength increased when the strain rate is higher. Tensile strength also increased with fiber content (Vf) up to 41%. The predominant failure mechanism is fiber rupture for the main directions and for the off-axis directions, the failure mechanisms are fiber pullout and delamination.

“…The failure modes were mainly fibre micro-buckling and delamination (Waas and Babcock, 1986;Soutis and Fleck, 1991). A localized failure in the vicinity of the hole was observed prior to catastrophic failure (Boey and Kwon, 2013). The damage propagation behaviours greatly depended upon the temperature (Vieille and Taleb, 2011).…”

Purpose This paper aims to study the effect of elevated temperature on the compression behaviour of carbon fibre polyphenylene sulphide (CF/PPS) laminates notched and unnotched specimens made by film stacking method (FSM). Design/methodology/approach The surface of CF was coated with a silane coupling agent to form an effective transition layer with PPS, so as to enhance the interfacial interaction between CF and PPS. Considering the influence of fabrication pressure, forming temperature and cooling rate on the properties of laminates to obtain a reasonable preparation process. Conducting a compressive experiment of notched and unnotched specimens at different temperatures, which failure modes were examined by scanning electron microscope and stereo microscope. Findings The experimental observations highlight that with the increase of temperature, the transition failure mode from fibre broken to kink-band appeared in unnotched specimens, which were closely attributed to the matrix state. The notched specimens appeared more complex failure mode, which can be attributed to the joint effect of temperature and opening hole. Research implications A simple way of FSM for composite material laminates has been developed by using woven CF and PPS films. Originality/value The outcome of this study will help to understand the compression response mechanism of composite materials made by FSM at different temperature.
