This article addresses the experimental investigation and modelling of the uneven fibre distribution inside yarns of a textile composite. The test data is given for the tri-axial carbon-fibre braid; a considerable irregularity is revealed for the fibre distribution along and across the yarns. The importance of this effect for the damage resistance is illustrated with a simple finite-element (FE...

Physical and mechanical performance of natural fiber composites can be tailored by hybridizing with synthetic fibers. Jute fibers are promising highly available at a low cost in some countries, they have been used several applications, the extra benefit helping socially depressed people who commonly explore this plant. This work investigates effect hybridization on properties jute/glass jute/ca...

A novel Bayesian optimisation framework is proposed for the design of stronger stacking sequences in composite laminates. The first to incorporate high-fidelity progressive damage finite element modelling a data-driven methodology. Gaussian process regression used as surrogate model, minimising number computationally expensive objective function evaluations. case open-hole tensile strength inve...

A major concern affecting the efficient use of carbon fibre reinforced composite laminates in the aerospace industry is the low velocity impact damage which may be introduced accidentally during manufacture, operation or maintenance of the composite structures. It is widely reported that the contact behavior of composite laminates under low-velocity impact can be obtained under quasi-static loa...

In this paper, a new shape memory alloy (SMA) hybrid basalt fibre reinforced polymer (BFRP) composite laminate was fabricated and a new surface modification method with both silane coupling agent KH550 and Al₂O₃ nanoparticles was conducted to enhance the interface performance. The mechanical performance of BFRP composite laminates with and without SMA fibres and the influence of SMA surface mod...

We reveal the sophisticated and hierarchical structure of honeybee combs and measure the elastic properties of fresh and old natural honeycombs at different scales by optical microscope, environmental scanning electron microscope, nano/microindentation, and by tension and shear tests. We demonstrate that the comb walls are continuously strengthened and stiffened without becoming fragile by the ...

Femur fractures are often treated by fixing metallic bone plates in the fractured area. But subjected to stress shielding. To overcome shielding, a material with similar strength and stiffness that of human can be better suited. The present study focuses on fabrication carbon-flax/bioepoxy hybrid composite. femur plate was modeled using SOLIDWORKS ® 2020 3D modeling software package. Hybrid com...

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...
