Summary: A high-shear rate processing method has been proposed to quickly and easily produce low-viscosity resin for manufacturing meltblown nonwoven fabrics, which were traditionally expensive and not widely available on the market. By using a high-shear extruder, polypropylene with the necessary melt flow rate was produced from standard grade resin, enabling the successful fabrication of meltblown nonwoven fabric sheets.

Summary: This study investigates the acoustic performance of fibrous sound absorbers incorporating nanofibrous structures. The results show that electrospinning nanofibrous structures on the back side of the nonwoven fabric enhances viscosity resistance absorption, while electrospinning on the front side changes the absorption mechanism to resonance type. Hollow nanofibers demonstrated superior acoustic behavior compared to core-shell structures. The increase of membrane thickness improved the acoustic performance at low and middle frequencies.

Summary: This research paper discusses the manufacturing and impact analysis of double fabric layered helmets, as well as the evaluation of energy and blocking forces in different zones of police-head protector shells. Results are compared with previous studies on single piece riot-police-helmet-shells, showing significant differences in impact resistance performance. This suggests potential for the development of riot-police-helmet-shells that can withstand high velocity impacts.

Summary: This paper investigates the ballistic mechanism of 3D angle interlock woven fabric (3DAWF) under normal and oblique impact. A mesoscale model of 3DAWF under different impact directions and angles was studied to reveal its ballistic mechanism. The numerical studies showed that the 3DAWF's ballistic performance increases non-linearly with impact obliquity and the ballistic mechanisms change with impact directions due to the anisotropic structure of 3DAWF. The impact damage mechanism, energy absorption evolution, and stress wave distribution of the 3DAWF under oblique high-velocity impact were also demonstrated. These findings are constructive for the application of 3DAWF in ballistic protection.

Summary: The study shows that the wadded TTAI reinforced composite exhibits higher energy absorption and efficiency in energy absorption compared to plain weave fabric reinforced composite. Additionally, it also demonstrates a reduced delamination damage volume and a highly fibrillated failure morphology at the impact location.

Summary: This study aims to predict fabric deformation during the draping process and develop a comprehensive understanding of fabric deformation using a discrete Finite Element Analysis (FEA) based on textile architecture. A new efficient discrete fabric modeling approach is proposed, representing textile architecture using virtual fiber tows modeled as Timoshenko beams connected by springs and dashpots. The model's predictive capability is demonstrated through predicting the deformation and shear angles of a fabric subject to hemisphere draping. The development of the virtual fiber tow model provides an efficient method to illustrate individual tow deformation during draping while achieving computational efficiency in large-scale fabric draping simulations.

Summary: A novel multiaxial 3D angle-interlock woven composites (MAWC) was developed and tested using different weave patterns to study the influence of bias yarns on in-plane shear performance and failure modes. Results showed that bias yarns significantly improved in-plane shear modulus and strength, with primary failure modes being fiber slippage, tow splitting, and interfacial debonding in MAWC architectures.

Summary: Experimental and numerical methods were used to study shear pre-deformed 3D angle-interlock woven composites under tension load. A novel non-orthogonal mesoscopic finite element model was developed to predict mechanical properties and reveal damage mechanisms. The effects of shear pre-deformed angles on the stiffness and strength of the composites were discussed based on simulation results.

Summary: The usage of textile composites as lightweight gadgets is increasing day by day. The application range varies from personal protective tools to aerospace vehicle parts. However, every specific application demands specific functionality. Anisotropic nature of textile materials makes it possible to design composites in structural as well as non-structural shapes. This research focuses on the fabrication of single and multilayered textile composites using cotton woven fabric and unsaturated polyester resin. The impact property of the resultant composite was analyzed by varying the degrees of curvature and fabric orientations. The results show that curved specimens have higher strength and increasing the number of layers increases the strength of the composite. The fabric orientation has no significant effect on double and triple layered composites.

Summary: Bagasse waste from the sugarcane industry was converted into useful composites in this study, with fibers treated with sodium hydroxide showing improved tensile properties. Hand lay-up technique was used to manufacture bagasse composite samples, with longer fiber length and higher weight percentage resulting in better tensile properties. Bagasse-cotton fabric composites were also produced, demonstrating higher tensile strength and strain, although modulus decreased due to cotton fabric elongation. It was observed that tensile properties decreased with increasing weight percentage, potentially due to incomplete wetting of bagasse fibers during manufacturing. Further investigation on this phenomenon is needed.
