Functionally Graded Natural Fibre and SiC-reinforced Polymer Composite: Mechanical Properties
Abstract: Multifunctional materials, also called functionally graded materials (FGMs), are based on natural fibres or fillers and vary in composition and/or microstructure to control functional, structural, or thermal, properties. Functionally graded materials (FGMs) have been created for use in spacecraft, aircraft, and other engineering applications because they can withstand extremely high temperatures. Particle-reinforced FGMs, which make up the majority of FGMs, are made differently depending on their position. The mechanical and …

Autonomous Agentic AI for Adaptive Cure Optimization and Defect Prevention in Thermoset Polymer Composite Manufacturing
Abstract: Thermoset polymer composites occupy a central position in modern structural manufacturing, from aircraft fuselages to wind-turbine blades. Despite progress in resin chemistry and fiber architecture, the “cure process” that transforms compliant preforms into load-bearing structures remains difficult to manage. Manufacturers encounter ‘voids’, “interlaminar delaminations”, and “spring-back distortion” when curing complex or thick-section parts. The cause is not ignorance of the relevant physics, but rather that ‘temperature’, ‘chemistry’, ‘rheology’, and ‘mechanics’ …

Image-Based Quantitative Mapping of Structure Property Relationships in Polymer Composite Materials
Abstract: The performance of polymer composite materials is intrinsically governed by their microstructural architecture, which is shaped by manufacturing conditions and constituent interactions. Despite extensive experimental characterization efforts, establishing transparent and quantitative structure–property relationships from microstructural images remains a challenge. In this study, an explainable image-driven framework is developed to systematically correlate microstructural features with composite property indicators. Microstructure images are processed to identify voids, fibers, and filler phases, from which …

The Effects of Hydro Confining Pressure on the Flow Properties of Sandstone and Carbonate Rocks
Abstract: There is a significant effect of the hydro confining pressure of the core holder on the flowing properties of the formation rocks. This effect is caused due to the mechanical elastic deformation of the core when carrying out laboratory studies of the water shutoff and polymer compositions. Consequently, this deformation will cause changing in the permeability and voids storage capacity of the studied core samples. Therefore, under the laboratory conditions …
