Summary: The study investigated the effects of stacking sequence and ply orientation on the mechanical properties of PALF/carbon hybrid laminate composites. Different laminate configurations led to varied tensile and flexural performance, with the highest strengths and moduli observed in specific configurations. Failure analysis revealed that failure typically initiated at the weakest PALF layer, with various failure modes observed.

Summary: This study investigated the potential of woven pineapple leaf fibre (PALF) in reinforcing epoxy resin (ER) composites. The results showed that the 3-layer woven PALF performed better in terms of tensile and flexural properties, and the composite with warp direction had slightly higher performance than the weft direction. Scanning electron microscopic (SEM) analysis revealed that the interfacial adhesion of the 3-layer woven PALF successfully transferred the load to the epoxy resin matrix.

Summary: The study shows that alkali-treated pineapple leaf fibers can improve the interfacial bonding with rice starch matrix, further increasing the tensile strength of the films. Incorporating PALF into rice starch matrix improves the dynamic mechanical properties and thermal stability of the films.

Summary: This study investigated the impact response behaviors of PALF/carbon hybrid laminate composites for different ply orientations and stacking sequences. The results showed that the hybrid effect of PALF and carbon as reinforcements improved the overall impact properties of the laminates. The stacking sequence and ply orientation had an influence on the energy absorption capacity of the laminates.

Summary: Synthetic fiber composites are widely used in various industries due to their high strength-to-weight ratio, but environmental concerns arise from their production and non-degradable characteristics. Natural fibers like PALF, derived from pineapple leaves, are biodegradable and can be used as a sustainable alternative in composite materials, offering solutions to environmental issues and economic opportunities for farmers and industries. This review paper discusses surface treatment methods, mechanical and thermal properties, and the potential for future research in PALF reinforced composites.

Summary: The study found that the physical and structural characteristics of PALF are similar to jute fiber, and in some cases PALF is even better. Additionally, PALF has a greater diameter compared to jute fiber, resulting in a smaller quality ratio value for PALF yarn than that of jute yarn.

Summary: The objective of this research is to investigate the suitability of olive tree leaves powder (OTL) as reinforcement in epoxy composites along with pineapple leaf fibre (PALF). The study found that increasing the proportion of PALF in the hybrid composites significantly improved impact strength, but the bending strength and flexural modulus were lower than the parent composites. DMA results showed that hybrid composites outperformed parent composites in terms of storage modulus, loss modulus, and damping factor.

Summary: The incorporation of roselle fibre reduced the workability of self-compacting concrete but improved mechanical characteristics. Higher fibre content resulted in increased compressive strength, splitting tensile strength, modulus of rupture, and modulus of elasticity. However, a 4% fibre addition may lead to a slight decrease in compressive strength and modulus of elasticity of the self-compacting concrete.

Summary: This study aimed to determine the physical and mechanical properties of pineapple leaf fibre (PALF) and Kevlar reinforced unsaturated polyester (UP) hybrid composites. The results showed that the hybrid composites exhibited superior physical and mechanical properties, including higher tensile strength, modulus, and flexural strength, as well as better impact resistance compared to pure PALF composites. SEM scans revealed a stronger interfacial adhesion between the fibres and matrix in the hybrid composites.

Summary: Due to their biodegradability, affordability, low density, and numerous other benefits, natural fiber polymer composites are preferred over conventional GFRP in maritime applications. However, their mechanical qualities deteriorate when exposed to moisture. This study explores the use of pineapple leaf fiber (PALF) as reinforcement in epoxy matrices, and the incorporation of nanoclay to improve mechanical and water absorption properties. The results show that the combination of 30 wt% PALF and 1.5 wt% nanoclay achieves the maximum mechanical properties.

Summary: The study demonstrates that alkali treated PALF can effectively enhance the thermal stability and mechanical properties of thermoplastic composites, as well as reduce water absorption. Alkali treated PALF can improve the compatibility between fibers and polymers, which is significant for substituting synthetic fibers.

Summary: The effect of granite powder grain size and grinding time on the properties of cement paste was studied. The best results were obtained for a sample with granite powder ground for 3 h, in which 50% of the particles were smaller than 4 mu m, and 90% were below 20 mu m, indicating the potential application of granite powder in cementitious composites.

Summary: Researchers have used various sources to calculate the successful management of Construction and Demolition Waste (C&DW). However, there is limited research in the field of Construction and Demolition Waste Management (C&DWM), leading to a lack of effective management techniques. This study proposes using a Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) model to predict the amount of waste materials obtained from a building at the end of its useful life. The results show that the proposed deep learning models outperform existing methods with an average R-squared value of 0.98 and a Mean Absolute Error of 18.1 and 20.14.
