Stiffness Estimates for Composites with Elliptic Cylindrical Voids [PDF]
Materials, 2020 A two-step homogenization procedure is presented to investigate the stiffness of a unidirectional continuous fiber-reinforced composite material containing voids of different shapes and volume contents. Since the Mori–Tanaka scheme is limited to moderate volume contents of the inhomogeneity phase, fiber and matrix are homogenized with semi-empirical ...

Effect Mechanism and Simulation of Voids on Hygrothermal Performances of Composites [PDF]
Polymers, 2022 Voids are comment defects generated during the manufacturing process and highly sensitive to moisture in the hygrothermal environment, which has deleterious effects on the mechanical performances. However, the combined impact of void content and water-absorbed content on mechanical properties is not clear.

Manufacturing Method of Carbon/Phenolic Composites and its Implication on Ablative Charactristics [PDF]
علوم و تکنولوژی پلیمر, 2013 Carbon/phenolic composites are used in the nozzle parts of solid rocket motors due to their heat-resisting, ablation, and high strength characteristics, which are required to endure the high temperature and pressure of combustion gas passing through the ...

Hierarchical structure of the cosmic web and galaxy properties [PDF]
Monthly Notices of the Royal Astronomical Society, Volume 527,
Issue 2, pp.4087-4099, January 2024, 2023 Voids possess a very complex internal structure and dynamics. Using $N$-body simulations we study the hierarchical nature of sub-structures present in the cosmic web (CW). We use the SpineWeb method which provides a complete characterization of the CW into its primary constituents: voids, walls, filaments, and nodes.
