“…Based on the previous researches, the nonlinear behavior of CF/PEEK unidirectional lamina can be described by the combination of orthotropic elastic model and plastic accumulation. [21][22][23][24] The plastic accumulation model applied in this study is based on the research of Sun and Wang. [23,24] Wang introduces elastic stiffness degradation model into elastic part of Sun's model to make the predicted more accurate.…”

“…Considering that CF/PEEK composites have a marked plastic stage compared to thermoset composites with epoxy matrix, [21][22][23][24]17] it is expected that the interference fit may offer a greater advantage in CF/PEEK riveted joints. Therefore, in the present paper, a nonlinear constitutive model of unidirectional CF/PEEK composite is proposed and implemented into ABAQUS user subroutine VUMAT.…”

Carbon fiber reinforced polyetheretherketone polymer (CF/PEEK) thermoplastic composites have a marked plastic yield stage compared to thermoset composites with epoxy matrix. During the interference fit riveting process, extrusion between rivet and composites laminate creates plastic deformation on the hole wall, which will enhance the bearing capacity of composites hole. Therefore, it is expected that the interference fit will play a greater advantage in enhancing the bearing strength of CF/PEEK riveted joint. Numerical and experimental study are applied to investigate the effect of interference fit on bearing strength of CF/PEEK riveted joint. Results show that the plastic deformation of CF/PEEK composites hole wall is positively correlated with the bearing strength of CF/PEEK riveted joint. When the interference fit size exceeds 2.6%, the bearing capacity of CF/PEEK riveted joint reduces because of the increase of fiber damage. It is concluded that the plastic deformation of riveted hole wall can enhance the bearing capacity of CF/PEEK riveted joint, while fiber damage reduces the bearing capacity of CF/PEEK riveted joint. As the increase of interference-fit size, bearing strength of CF/PEEK riveted joint raises first then decreases, the appropriate interference-fit size is in the range of 2.0%~2.6%, which is larger than that of thermoset composites.

“…• On the exposed surface: 401 C under 40 kW/m 2 In tensile specimens subjected to one-side heat fluxes, there are temperature differences within the laminates (Figures 7 and 8). These differences leading to a heterogeneous stress distribution within the laminates, the tensile curves are presented in terms of tensile force rather than tensile stress (Figure 9).…”

Study of thermomechanical coupling in carbon fibers woven‐ply reinforced thermoplastic laminates: Tensile behavior under radiant heat flux

et al. 2020

The present work focuses on the thermomechanical behavior of carbon fibers woven‐ply polyphenylene sulfide (PPS thermoplastic)‐based composite materials subjected to the combined action of a tensile mechanical loading and one‐side heat flux (40‐60 kW/m2) representative of fire exposure. An experimental bench was specifically designed to provide an insight in the coupling between a medium heat flux thermal aggression and a tensile mechanical loading (either in monotonic or creep mode) within quasi‐isotropic C/PPS laminates. When subjected to a monotonic tensile loading, a 50% increase in the heat flux lead to a 50% increase of the temperature at the exposed surface resulting in a 10% decrease in the maximum load borne by the laminates. When subjected to a creep loading at 60 kW/m2 (worst case scenario with the cone calorimeter), by dividing by 2.6 the applied creep stress (from 31% to 12% of the ultimate strength σ0u), it results in a time‐to‐failure multiplied by 2.5. The temperature distribution on the exposed and back surfaces are measured to evaluate the influence of PPS matrix melting, pyrolysis, and fibers oxidation on the stress redistribution within the laminates plies.

“…Dynamic mechanical analyzer (DMA) is a common method to test the dynamic mechanical properties of materials, which is widely used to evaluate the dynamic mechanical behavior of various materials. [18][19][20][21] At the same time, it can provide the tensile mode required for flexible material testing. Venkateshwaran et al 22 carried out a dynamic mechanical analysis on the handmade banana fiber/epoxy composite at different frequencies to obtain the dynamic mechanical properties of the composite.…”

The dynamic thermo-mechanical analysis test is performed on the architectural coating fabric based on the dynamic thermo-mechanical analyzer (DMA). The effects of excitation frequency, constant temperature, and dynamic temperature on the dynamic mechanical properties of architectural membrane materials are discussed. Through analysis and discussion, the various rules of damping loss factor, loss modulus, and storage modulus of architectural membrane materials in the application temperature and frequency range are obtained. As the frequency of the external excitation force increases, the storage modulus, loss modulus, and loss factor all increase, while the influence of temperature is nonlinear. Under the action of dynamic temperature and constant temperature, the difference between storage modulus and loss modulus is obvious, but the difference of loss factor is small. Due to the anisotropy of the polyester fiber substrate, the damping characteristics of the membrane material in the warp and weft yarns are different regardless of the effect of external excitation frequency or temperature. The discussion in this article provides a theoretical basis for further research on the damping characteristics of membrane materials and the vibration response of membrane structures.
