Summary: The study investigates the relationship between the thickness and flexural strengths of laminar carbon fibre reinforced polymer (CFRP) plates through experimental and analytical methods. A simple composite formula is used to link the thickness effect to the ply thickness. Different sample thicknesses are tested, and the flexural strengths are evaluated and modeled using the Strength of Materials (SOM) formula and the simple composite formula. The ASTM standard D7264 is justified analytically, suggesting that a thickness of 4 mm is sufficient for CFRP plates with typical ply thicknesses around 120-130 μm.

Summary: The research focuses on characterizing the mechanical properties and morphology of polyester/coconut shell powder composites filled with corn husk fibre (CHF). Results show that increasing CHF content leads to higher flexural strength but lower tensile strength of the composite. The enhancement of the interfacial bonding between CHF-CSP-polyester and the reduction of fiber pull-outs contribute to the improved properties.

Summary: In this study, NBR/WLF composites with different weight percentages were fabricated and evaluated for their mechanical properties, dynamic mechanical properties, solvent absorption, and morphology. The results showed that increasing WLF content up to 50% improved tensile strength and tear strength, while further increasing WLF content decreased these properties. Additionally, hardness and solvent resistance of the composites increased with higher WLF content.

Summary: This study investigates the strength, durability, and microstructural properties of Pervious Concrete (PC) made with Fly Ash (FA) and Silica Fume (SF) substitution. Nine different mixes of pervious concrete were cast to evaluate the study's objective. The influence of FA and SF on various properties of pervious concrete, such as workability, porosity, compressive strength, and acid resistance, were assessed. The study also utilized Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) for microstructural analysis. The results showed that substituting 10% of FA and SF significantly improved the strength and durability properties of PC, with a notable increase in compressive strength at different curing ages. The microstructural analysis revealed densified micrographs with even-layered C-S-H and C-A-S-H gel formation, contributing to the improved mechanical and durability characteristics of pervious concrete.

Summary: The study introduces a simplified approach to correlate the experimental tensile strength values of randomly oriented short fiber reinforced polymer-based composites, deriving a constitutive model based on a rule of mixtures. The experimental results demonstrate the significant influence of fiber orientation and interfacial stress on the composite's tensile strength, with the proposed model showing good agreement with experimental data. The analytical model outperforms other models in accurately predicting the behavior of short fiber reinforced composites.

Summary: The present research investigated the mechanical properties of wood flour reinforced polyethylene polymer composites with varying wood flour size, aspect ratios, and mold injection temperature. Results showed that reducing the wood flour size decreased the tensile strength and modulus, flexural strength and impact energy, while increasing the flexural modulus. Additionally, increasing the injection molding temperature decreased the tensile strength and modulus, impact energy, while increasing the flexural strength and modulus. Thus, optimizing the injection molding temperature can improve the mechanical properties of the composite.
