Summary: The drapability of a textile composite reinforcement refers to its ability to be formed on a double curved shape without wrinkling. By analyzing the deformation modes and internal virtual works during draping, a physics-based Drapability Ratio can be determined, which is influenced by the in-plane shear stiffness and bending stiffness of the textile reinforcement. This ratio helps identify the suitable reinforcement for a given geometry.

Summary: The use of hemp fibers as reinforcements for composite materials is not common, despite the increasing interest in natural fibers in this field. This study compares the properties of a quasi-unidirectional fabric and two woven fabrics (balanced and unbalanced in terms of fiber content) at different levels: mechanical and preforming properties of the reinforcements in dry state, and mechanical properties of composite materials reinforced by these fabrics. The results show that the quasi-unidirectional reinforcement exhibits enhanced properties at both fabric and composite scale, making it a promising alternative to flax-based structures already available on the market.

Summary: Parachutes and other inflatable aerodynamic decelerators commonly use flexible fabrics for their lightweight and high load-carrying capacity. The behavior of fabrics during complex deformations is mainly influenced by their shear properties, which can be explained by the shear stiffness or shear modulus. This paper proposes a coupling method based on computational fluid dynamics and structural solver LS-DYNA to investigate the effect of shear modulus on the inflated shapes of parachute canopies. The findings reveal that different shear moduli have little effect on the overall shape and in-plane shear strain of parachutes, but significant effects on in-plane stress distribution and wrinkles.

Summary: Hemp is gaining popularity as a valuable source of fine fibers for garment textiles. In the Normandy region, the existing flax industrial value chain is being adapted for hemp, with successful results demonstrated in a complete value chain from field to fiber production. The study showed that early harvesting and optimized scutching process parameters can yield about 18% of the stem mass as long fibers, with a production rate of 1.1 tons per hectare. The tensile properties of the long fibers are suitable for textile applications, and growing hemp for textiles can provide higher incomes for farmers compared to traditional crops.

Summary: In this study, the influence of noncircularity and cross-sectional area evolution on the measurement of mechanical properties of fibres is investigated. The results show that the circular assumption underestimates the elastic modulus and stress at failure for fibres with noncircular cross sections. Additionally, a numerical model is developed to accurately determine the elastic modulus of fibres with elliptical cross sections. Recommendations are made to better account for the variability along a fibre in cross-sectional area evaluation.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
