“…[ 2 ] Properties of CFRTP are decided by CF, thermoplastic matrix, as well as the interphase formed between the two phases. The interface transfers the load from matrix to fibers, [ 3 ] which is the crucial region determining the set of composite properties, such as mechanical performance, reliability, and so forth. [ 4–6 ] The interface theories of CFRTP mainly include physical bonding, such as wetting behavior, [ 7 ] mechanical interlocking, [ 8,9 ] interfacial crystallization [ 10 ] and chemical bonding.…”

Carbon fiber (CF) reinforced polyphenylene sulfide (PPS) composite shows extraordinary thermal stability, chemical resistance, and processability. The interface between CF and PPS transfers the load, and its properties are crucial to determine composite properties such as mechanical performance, reliability, and so forth. This work explores the relationship between surface properties of CFs (with/without sizing layer) and the interfacial properties of CF/PPS composite. X‐ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscope were employed to evaluate surface physicochemical properties of CFs, and reveal the increasing roughness and decreasing content of functional groups on the CF surface after desizing. Inverse gas chromatography and dynamic contact angle tests were adopted to characterize the surface energy of CFs, and present that the dispersive component of surface energy increases, while the polar component decreases, and the total surface energy is barely changed after desizing. Differential scanning calorimetry measurement reveals the increasing crystallinity of CF/PPS after CF desizing. Microbond test was performed to analyze interfacial shear strength (IFSS) of CF/PPS, displays that IFSS keeps almost constant after CF desizing. The results demonstrate that the surface energy of CF is important to the interfacial crystallinity, but not the critical factor for interfacial strength of CF/PPS composite.

“…[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. [31,32] TP laminates usually demonstrate lower structural loss up to 200%, lower contact force by 14%, and lower absorbed energy by 48% compared with those of TS counterparts.…”

“…Significant differences are usually observed in terms of internal damages when composite laminates are subjected to quasi-static indentation or dynamic loadings. [28,29] From the brief literature review, it appears that the influence of temperature on the impact behavior of thermoplastic-based laminates significantly depends on the temperature testing conditions, and more specifically the thermally induced damages. In other words, depending on the physico-chemical phenomena taking place within polymer-based laminates, it is expected that the polyether ether ketone (PEEK) matrix will experience various degradation mechanisms that will change their capabilities to transfer the mechanical loading when laminates are subjected to low velocity impacts at high temperature.…”

High temperature in situ impact testing of hybrid thermoplastic polyether ether ketone laminates

et al. 2023

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.

“…Recently, researchers have gained interest in the three‐Network model (TNM) [ 31 ] for accurately predicting the nonlinear, viscoelastic, or viscoplastic behavior of different polymers at small and large strains. TNM has been studied for various applications, including the effect of thermoplastic composites, [ 32 ] to explore the time and temperature‐dependent behavior of high‐density polyethylene, [ 33 ] to design novel polymer‐on‐metal hip joint prosthesis, [ 34 ] and to investigate the strain rate and temperature effect on epoxy polymer. [ 35 ] Although we have a wide range of models available in the literature to predict the mechanics of traditional hyperelastic materials, the behavior of hollow melt–extruded fibers has yet to be dissected extensively.…”

Melt‐extruded hollow thermoplastic fibers are a new class of materials for advanced applications, i.e., robotic clothes, stretchable touch and twist sensors, and programmable knitted textiles. Under large mechanical deformation (strain), such materials exhibit hyperelasticity. However, fundamental knowledge of strain‐energy density harnessing integrated computational materials engineering (ICME) has remained untapped for hollow fibers. Due to this key knowledge gap, most emerging applications demand iterative and costly approaches to producing and studying hollow fibers. Herein, a data‐driven pathway harnessing the ICME is introduced to study, predict, and optimize the hyperelastic behavior of hollow fibers. MCalibration software is used to calibrate the material properties of the fibers utilizing the Three‐Network Model (TNM) and emulated experimental stress–strain behavior in a finite‐element‐based multiphysics environment (COMSOL) with 99.99% confidence. The feasibility of predicting strain‐energy density is shown to modulate shape and geometries for new understandings without running cost‐incurring melt extrusions or experiments. Furthermore, the strain‐energy density is leveraged as a tool to attach fibers on fabrics that otherwise need iterations. As a proof‐of‐concept, fibers to fabrics are attached for wearable microfluidic demonstrations. This ICME approach can be extended to design the next generation of pre‐programmed, undiscovered functional devices fabricated from hyperelastic hollow fibers.
