Summary: This paper presents a method for the detection and size estimation of impact damages in glass fiber reinforced polymers. Capacitance measurements between carbon fiber bundles are used to detect the damages, and the magnitude of capacitance decrease is used for size estimation.

Summary: The study demonstrates that the influence of fiber orientation and applied strain rate on the tensile strength can be multiplicatively decomposed for fiber-reinforced systems, regardless of various factors such as fiber type, length, weight fraction, matrix type, and interfacial interaction level. This factorization suggests the possibility of significantly reducing experimental efforts required for composite characterization. The anisotropic viscoplastic model developed by van Erp et al. accurately describes the load-angle and strain-rate dependence of tensile strength, as well as provides accurate creep lifetime predictions for different loading angles when combined with a critical strain concept.

Summary: A new fiber-reinforced high-performance lightweight engineered cementitious composite (LWECC) was proposed and thoroughly investigated for its fresh properties, compressive strength, and flexural strength, then calibrated through a printability assessment. The addition of hollow glass microspheres (HGMs) significantly improved the lightweight property of the material but inevitably negated mechanical properties. Superior toughness was observed when the printed filament was perpendicular to the loading direction, resulting in a 63% increase in compressive strength and a 40% increase in flexural strength.

Summary: Fibre-reinforced polymeric composite materials are increasingly being used in the repair and replacement of metallic materials due to their high stiffness. This study investigates the effects of fibre volume fraction and stress level on the fatigue performance of glass fibre-reinforced polyester (GFRP) composites, and validates prediction models for fatigue life.

Summary: This review article investigates the fibre-matrix interface in fibre-reinforced polymers (FRPs) and describes four main interface characterisation methods. The article reviews the interface-forming mechanisms, three primary factors affecting the interface, and critically evaluates detailed data reduction schemes, numerical approaches and challenges. Finally, comprehensive conclusions and future research directions are provided.

Summary: Glass Fibre Reinforced Gypsum (GFRG) panels filled with reinforced concrete (RC) are used as load-bearing walls and can also be used as floor and roof slabs. The contribution of GFRG to flexural strength and stiffness is significant and provision of joints in the GFRG does not affect the performance of the composite slab.

Summary: This study systematically investigates the effect of fibre length on the mechanical performance of MJF-printed GF/PA12 composites, showing that longer fibres promote fibre alignment but also increase porosity in the composite parts. When GFs with an average length of 226 pm are added, the ultimate tensile strength and tensile modulus of the composites are significantly improved in the powder bed spreading direction.

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.

Summary: The mechanical properties of recycled carbon and glass fiber-reinforced epoxy composites were investigated using finite element methods to develop FE models for analyzing their tensile and impact behaviors. The developed models accurately predicted the results of defect-free recycled composites, demonstrating the potential for validating complex mechanical properties and damage behaviors in experimental testing.

Summary: The study found that the annealing process can significantly improve the mechanical performance of continuous and chopped fibre reinforced polyamide 6 material in the build-up direction, including an increase in Young's modulus and ultimate tensile strength. Additionally, air voids within the parts were identified as the main cause of embrittlement.
