“…9,10 Usually, creep tests require long experimental times, large specimens, and high loads (over 35 MPa), making creep experiments time-consuming and costly. 11 Fancey 5,12 mentioned the possibility of predicting the mechanical tensile modulus using a low-stress creep response, aiming to optimize the results. In this regard, dynamic mechanical analysis (DMA) is an excellent alternative since the tests use smaller specimens and loads.…”

This work presents the short-term creep behavior of novel epoxy composites reinforced by post-consumed yerba-mate (YM). Particulate composites were manufactured using 5, 10, and 20 wt.% of YM. The composite morphologies were related to the dynamic mechanical and creep behavior at the glassy state (∼30°C). Creep tests were performed using three different stress loads (1.5, 3.0, and 6.0 MPa). Weibull model, Artificial Neural Network (ANN) approach and Response Surface Methodology (RSM) were used to fit the experimental curves and to predict results. A better fit was obtained using the ANN approach than the Weibull model due to the capability of ANN to learn from own data and in fitting complex nonlinear data. The RSM approach proved to be an intelligent and reliable technique to access a higher range of results, reducing experimental time and cost and keeping statistical significance. Also, the present methodology can be extended to model and predict other properties and/or optimize parameters.

Traditional thickness-prediction methods underestimate the actual dome thickness at polar openings, leading to the inaccurate prediction of the load-bearing capacity of composite hydrogen storage vessels. A method of thickness prediction for the dome section of composite hydrogen storage vessels was proposed, which involved fiber slippage and tow redistribution. This method considered the blocking effect of the port on sliding fiber tows and introduced the thickness correlation to predict the dome thickness at polar openings. The arc length corresponding to the parallel circle radius was calculated, and then, the actual radius values corresponding to the bandwidth were obtained by the interpolation method. The predicted thickness values were compared with the actual measured thickness. The maximum relative error of the predicted thickness was 4.19%, and the mean absolute percentage error was 2.04%. The results show that the present method had a higher prediction accuracy. Eventually, this prediction method was used to perform progressive damage analysis on vessels. By comparing with the results of the cubic spline function method, the analysis results of the present method approached the actual case. This showed that the present method improved the accuracy of the design.

“…Non-Fickian behaviors were found in both cellulose fiber and synthetic fiber woven composites [ 18 , 19 , 25 , 26 , 27 ]. Perrier et al [ 25 ] investigated the water uptake of hemp-fiber-reinforced plain weave composites, showing that the weave pattern had an influence on moisture diffusion, while non-Fickian absorption was observed, which have may been related to the different types of fiber reinforcement.…”

“…A dual-diffusivity model was then successfully established to describe this non-Fickian behavior. Eggers et al [ 27 ] investigated the moisture diffusion behavior of filament-wound composite rings under harsh environments. The initial experiment results at room temperature and with hot water fit Fick’s law, while ±60/±90 composites showed non-Fickian behavior, namely fast transient diffusion at the beginning followed by a slower diffusion rate.…”

Cellulose-fiber-reinforced plain weave composites absorb lots of water from humid environments because of their inherent susceptibility to moisture. Moisture absorption experiments with cellulose fiber plain weave composites have been reported by some researchers; however, few theoretical studies have been performed to date to predict their moisture diffusion behavior. In this paper, the moisture diffusion behavior of cellulose-fiber-reinforced plain weave composite is predicted using a novel superposition method considering its microweave pattern. The overall moisture uptake of the composite is treated as moisture absorption superposition of the fiber bundles part, resin part, undulated fiber bundles and resin-rich part in the unit cell. The moisture diffusion of the undulated fiber bundles and resin-rich part is more complicated than the other parts; thus, a solution for a unique three-phase diffusion problem is used to solve this special moisture diffusion issue. Both finite element analysis and experiments are carried out to validate the proposed approach, with the results showing that the predictions can effectively characterize the moisture diffusion behavior of cellulose-fiber-reinforced plain weave composites.
