Flax bundles exhibit the same non-linear behaviour under mechanical stress as elementary fibres. Video recorded tests revealed that during tensile loading, fibre bundles undergo a coupling between tension and rotation. Three different scenarios were identified: pure tension, tension-torsion coupling to failure, and partial tension-torsion coupling ending before specimen failure. Elementary fibre decohesion was also observed during fibre bundle tensile tests. Overall, the tensile behaviour of fibre bundles is influenced by their initial morphology, especially the degree of twist, and the mechanical efficiency of the lamella between the elementary fibres (middle lamella). In addition, the influence of the geometric model used to represent the cross-section on the mechanical properties was investigated using circular and elliptical models. The results show a significant dependence on the geometrical model considered. Therefore, a standardised method for measuring the cross-sectional area of plant fibres is required to enable comparison of results from the literature.

AB - Drilling multidirectional (MD) carbon fiber reinforced polymers (CFRPs) has posed tremendous challenges to modern manufacturing community due to their unique properties including anisotropy and heterogeneity. Critical defects such as delamination, burrs and tearing are vital issues to be finely addressed for the industrial applications. To deal with the technical issues, the current study analyzes the damage formation and surface integrity for MD-CFRP drilling via both numerical and experimental approaches. The key novelty of this research lies in uniquely addressing the interfacial interaction between individual plies and integrating the vital effect of ply directionality on drilling responses. Based on the developed macroscopic CFRP models, drilling simulations have been conducted along with cutting experiments. The current work offers a comprehensive understanding of how variations in drilling parameters influence the machinability aspects and cutting-induced damages for MD-CFRP laminates. The dynamic delamination formation, which was not fully addressed in traditional experiments, is revealed in the study. The burrs are mainly formed in the exit side of cut CFRP holes and are primarily influenced by the feed rate. Increasing the feed rate significantly exacerbates the tearing damage by 0.18 mm2, while elevating the spindle speed from 1326 to 5305 rpm slightly reduces tearing by 0.03 mm2. To minimize surface damage, low feed rates and moderate spindle speeds are recommended for use from the industrial point of view. The results obtained provide technical guidance and practical implications to realize damage-free drilling of MD-CFRPs for industrial applications.

AB - Although polymer composites are increasingly used in structural applications, methods for predicting their creep time to failure are still not accurate, generalizable, or efficient enough. Most approaches rely on model fitting to numerous experimentally measured creep rupture points, making them costly and labor-intensive. This study presents a novel method for predicting the creep time to failure of thermoplastics and thermoplastic composites, based on a master curve constructed using the time–stress superposition (TSS) principle combined with a constant stress-rate loading curve. Our approach allows the estimation of stress–time and strain–time creep rupture envelopes. The method was validated through tests on injection-molded polypropylene (PP) and glass fiber–reinforced PP (PP + GF) composites with varying fiber contents for tensile and flexural load. Compared to established models, our stress-time creep rupture prediction outperforms the Reiner–Weissenberg, Modified Reiner–Weissenberg, Maximum strain, and Maximum work stress models. We showed that the instantaneous strength parameter (σR) introduces errors in these traditional methods. Our stress-time creep rupture prediction matches the accuracy of the Power law and Zhurkov models and does not rely on σR. Moreover, it requires significantly less measurement data, making it more robust and less sensitive to uncertainties associated with long-term extrapolation and parameter estimation. Overall, our approach provides a simple yet reliable tool for predicting the creep time to failure of thermoplastic composites, and it has high predictive accuracy based solely on experimental data.

AB - Mechanochromic materials, which exhibit visible color changes in response to mechanical stress, offer significant potential for real-time damage detection and structural health monitoring. However, many existing systems suffer from high activation thresholds and limited operational temperature ranges, which hinder their practical application in complex environments. In this study, we present the development of a Rhodamine-functionalized epoxy composite (Rh-MC) reinforced with nano-Al2O3, demonstrating excellent mechanochromic performance across a wide temperature range (-60 degrees C similar to 140 degrees C). Under compressive stresses as low as 150 MPa, the composite undergoes progressive color changes and fluorescence enhancement due to the ring-opening of Rhodamine units, exhibiting a strong linear correlation between applied stress and fluorescence intensity ratio. The incorporation of nano-Al2O3 significantly enhances the mechanical properties of the composite, promoting uniform stress transfer at the bulk scale while simultaneously amplifying local stresses near mechanophores, thereby enabling more efficient mechanochromic activation. Reversibility tests demonstrate that the mechanochromic signal can be thermally erased, confirming the recoverable nature of Rhodamine activation and the thermal stability provided by the nano-filler. To the best of our knowledge, this is the first report of a mechanochromic composite exhibiting reliable, reversible, and quantifiable stress responses across such an extensive temperature range. This enables the potential application of Rh-MC as a robust all-climate, multifunctional material platform for stress visualization, damage pre-warning, and intelligent sensing in harsh service environments.
