“…Thermoplastic composites have gained increasing attention for their higher toughness and better damage tolerance than thermoset composites. [1][2][3][4] A few references have compared the low velocity impact behaviors of thermoplastic laminates at room temperature (RT) [3][4][5][6][7][8][9][10] as well as at low, [11][12][13][14][15][16] high temperatures, [17][18][19][20][21][22][23][24][25][26] including strain rate effects. [27][28][29][30] The influence of hybridization on the impact behavior was investigated as well.…”

In order to evaluate the severity of thermal degradation on the impact response of carbon (C) and glass (G) fibers reinforced polyether ether ketone laminates, low velocity impact tests have been conducted at a temperature higher than the glass transition temperature (150°C). An instrumented Charpy pendulum (CP) equipped with a heating device was specifically designed to estimate its capability to perform low velocity impact tests at high temperature. The first important effect resulting from temperature increase is a reduction of the impact energy required to induce the barely visible impact damage (BVID), whose role is utmost important regarding the damage tolerance. The second effect is that temperature has also a tremendous influence on the internal damage as there is virtually no delamination at high temperature for impact energies. Finally, compared with the impact behaviors observed with the same laminates impacted with a drop tower and quasi‐static indentation, the impact velocity is about 2.5–3 times as low during CP impacts. As a result, slow loading rates are instrumental in increasing both the dissipated energies and the permanent indentation (PI) values (1.6–2 times as high) that are always higher than the BVID. Ultimately, as higher PI is usually correlated to higher impact damage tolerance.

“…Boccardi et al [9] used infrared tomography to study the effect of frequency on the temperature of cantilever glass-and jute-based woven thermoplastic composite specimens subjected to cyclic bending. Sorentino et al [10] fabricated and characterized polyethylene naphthalate (PEN) thermoplastic composites at 100 • C by 3-point bending, DMA and impact tests. As far as shear loading characterization is concerned, Hufenbach et al [11] performed Iosipescu tests on woven thermoplastic composites and used high-speed camera and digital image correlation for studying the deformation and failure in order to develop material modeling strategies in commercial finite element software.…”

The effect of hot-wet storage aging on the mechanical response of a carbon fiber polyether ether ketone (PEEK)-matrix woven composite has been studied. A wide range of static loads and selected cyclic load tests on the interlaminar fatigue strength were performed. Static tests were conducted in batch mode, including on- and off-axis tension, compression, flexure, interlaminar shear strength (ILSS) and fracture tests in Modes I, II and I/II. Respective mechanical properties have been determined, indicating a degrading effect of aging on strength-related properties. The measured response in general, as well as the variance quantified by batch-mode test execution, indicated the appropriateness of the applied standards on the material under consideration, especially in the case of fracture tests. The material properties presented in the current work may provide a useful basis towards preliminary design with PEEK-based woven thermoplastic composites during service in aerospace applications.

“…To take full advantages of thermoplastic composites, it is important to clarify the mechanical behaviours of thermoplastic composites under different loading conditions Hyert, 1993, 1994;Thomason and Vlug, 1996;Sorrentino et al, 2017aSorrentino et al, , 2017bErkendirci, 2016;Duan et al, 2016;Tan et al, 2016;Koricho and Belingardi, 2015;Sorrentino et al, 2017aSorrentino et al, , 2017b. Except the investigations at room temperature (RT, 25°C), considerable attentions have been paid upon the mechanical properties of thermoplastic composites at elevated temperatures (Gabrion et al, 2016;Eftekhari and Fatemi, 2016;Walther, 1998;Vieille and Taleb, 2011;Sorrentino et al, 2017aSorrentino et al, , 2017bVieille et al, 2016). However, the complex compressive failure behaviours of fibre reinforced thermoplastic laminates at high temperature were seldom studied.…”

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.
