“…In comparison with a GA, the authors concluded that the approach proposed was, in general, faster, and less expensive. Avoiding the direct optimization of the ply-thickness and fibre orientation, Demir et al (2019) [60] applied a leastsquare optimization approach, with continuity constraints, to optimize the lamination parameters of a composite [2]. The authors argue in favour of this parametrization as it leads to the stiffness becoming a linear function of the lamination parameters, instead of a nonlinear trigonometric function of the fibre angle, making it more suitable for gradient-based methods.…”

“…The authors argue in favour of this parametrization as it leads to the stiffness becoming a linear function of the lamination parameters, instead of a nonlinear trigonometric function of the fibre angle, making it more suitable for gradient-based methods. Additionally, this parametrization accounts for any number of layers and possible fibre angles [2]. After obtaining the optimized lamination parameters, the authors used a material library consisting of desired fibre angle and stacking sequences.…”

“…13 Composites are materials formed via two or more materials for achieving properties better than lone materials. 14,15 Matrix and reinforcement are significant components of modern composites; the matrix is a continuous phase providing shape to composite while reinforcement could be continuous or discontinuous responsible for mechanical stability of composites. 16 Textile based composites consist of textile materials, e.g., fibers, yarns and fabrics as reinforcements.…”

The research aims the development of knitted reinforcement structures for inducing self-diagnostic properties into knitted reinforced composites for structural health monitoring. Conductive carbon fiber was used in knitted inlaid structures as inlay yarns, and l × 1 Rib knitted base fabric of polyester filament yarn was used for knitting. The reinforcement’s conductive nature induced self-diagnostic properties into composites using correlation of mechanical damages and changes in electrical resistance values. Single and double stimuli layers and inlay patterns of 3 × 1, 6 × 1 and 9 × 1 was used to check their impact on self-diagnostic properties. Mechanical testing and real-time electrical resistance monitoring proved knitted structures as a solution to induce self-diagnostic properties into composite materials. Composites having double stimuli (conductive) layers exhibited better self-diagnostic properties than single stimuli layer composites, and the self-diagnostic properties also improved as the inlay pattern of reinforcement moved from 9 × 1 to 6 × 1 and 3 × 1 inlay. Such knitted reinforced self-diagnostic composites could be practically used in structural health monitoring applications, e.g., complicated structures of large buildings infrastructures and machinery which require record of each minor happening with structures to keep smooth and successful running of the system.

“…Composites have been used for many purposes in our daily lives where they enhance the material, making it lighter and more durable. The composite manufacturing method was versatile, efficient, and high-tech [1]. The four categories of fibre-reinforced composites described by their matrices are metal matrix composites (MMCs), ceramic matrix composites (CMCs), carbon/carbon composites (C/C), and polymer matrix composites (PMCs) or polymeric composites [2].…”

Natural fibres nowadays have been famously investigated as alternative fibres due to the depletion of petroleum sources. There are several natural fibres such as jute, hemp, sisal, kenaf, and pineapple leaf that have been actively investigated in terms of their mechanical properties. Malaysia produces kenaf and pineapple as its main commodities. The sources of kenaf and pineapple leaf can be obtained easily. Therefore, this research is focusing on the kenaf and pineapple leaf. Previous researchers have proved that the kenaf and pineapple leaf fibres have good mechanical properties. This study aims to characterized the mechanical properties of a hybrid kenaf and pineapple leaf Fibre (PALF) epoxy composite for engineering application. Different compositions ofkenaf and PALF were formulated to compare the best composition in terms of maximum stress. The tensile test was performed via the Universal Testing Machine. Hybridization of pineapple leaf fibre and kenaf fibre at a composition of 75 % pineapple leaf fibre to 25% kenaf fibre which is 87.06 MPa, shows the highest maximum stress. The result found that this composition performs better than the previous investigation of hybrid natural fibre. As a result, the findings of this study may provide a clear indication that natural fibre should be used rather than being discarded, particularly by the agricultural industry.
