Summary: The study shows that increasing scarf angle reduces the tensile strength of the repaired composite structures, resulting in different types of failure. Finite element analysis using cohesive zone modeling accurately predicts the experimentally observed response, with stress concentration distribution over the bonding area playing a crucial role in determining the failure type. Further investigation reveals that adhesive defects can significantly decrease the strength of the bonded specimens.

Summary: This study investigated the in-plane shear deformation of unbalanced 3D interlock woven reinforcement through experiments and finite element modeling. The bias extension process was simulated from macro and meso scales, showing three stages of deformation: meso scale deformation stage, multiscale deformation stage, and reinforcement failure stage. The results were consistent with experiments, revealing the asymmetric deformation and failure mechanisms of the reinforcement material.

Summary: A novel deep neural network was proposed for predicting the mechanical behavior of plain carbon fabric reinforced woven composites. The network was trained using a pre-simulated stress-strain curve database based on yarn structures and material properties. Micro-mechanics-based multi-scale analyses were conducted for progressive damage analysis, and the network was optimized using the Hyperband algorithm. The predicted mechanical behavior of the composites was validated through mechanical tests.

Summary: The study focuses on the design requirement of soft ballistic armour, which aims to achieve maximum ballistic energy absorption, lower backface deformation, and minimum weight. The properties of yarn mechanical play a crucial role in determining the armour characteristics. The study aims to find the optimal combination of yarn mechanical properties that can satisfy all the design objectives. A new parameter, Inertial Work, is introduced to categorize the armour backface deformation in a mass normalized manner, and a Specific Ballistic Energy Absorption parameter is used to compare fabrics of different densities. The study also analyzes the ballistic response of woven fabrics commonly used in ballistic protection and proposes a concept of hybridized multilayer-multimaterial armour to address the limitations of a single material armour. The results show that hybridization significantly influences the ballistic performance of the armour, and the arrangement of different layers of materials can result in higher energy absorption and lower deformation.

Summary: Previous studies have focused on simulating ballistic impact on fabric panels at the yarn level, failing to capture the responses of individual fibers. This study uses a finite element model at the fiber bundle level to investigate the influence of fabric architecture on ballistic responses. Ballistic tests were conducted on fabrics with different architectures, revealing that yarn cross-section shape and yarn crimp ratio are dominant factors. Finite element modeling showed an increase in frictional energy dissipation during ballistic impact, and the aspect ratio and crimp ratio significantly affect energy absorption.

Summary: This study evaluates the deformation of plain woven composite structures induced by the curing process. The effective material property is calculated by considering fabric parameters closely related to the material properties. The theoretical models for predicting the cure behavior and effective material property are incorporated into finite element-based three-dimensional cure simulation. The results revealed the relationship between deformation and composite yarn thickness, as well as the gap between adjacent yarns. The process-induced deformation considering fabric parameters can contribute to improving the manufacturing quality of woven composite structures.
