Abstract Structural natural composites are synthesized and maintained by living organisms in mild conditions of temperature and pressure or in challenging aqueous saline environments unlike their synthetic counterparts, having remarkable properties. The study of the properties of bones, trees, or sea shells allows con…
Abstract Ceramic matrix composites today are being developed for applications in thermal structures, heat exchangers, and a number of applications involving extreme conditions. Nanofibers have great potential for enhancing the properties of ceramic composites. In the recent years, there has been a growing interest in…
In a glass of champagne, glittering, pearl-like bubbles rise. Why do most of them form at definite spots and according to which laws do they move to the surface?
Abstract Sandwich composite panels are being primarily utilized in many engineering sectors such as civil, infrastructure, mechanical, aerospace, marine, space, and nuclear industry primarily because of their high strength and stiffness to low weight ratio. This article considers primarily sandwich composite construct…

Abstract This article discusses many different aspects of 3D woven textile composites. The basics of 3D weaving are introduced along with the fabrication techniques and a discussion of the general types of architectures. Mechanical properties are then examined showing the benefits and drawbacks of the architecture sys…
Abstract Since the last decade, the whole world is facing a sharp increase in energy consumption in conjunction with a fast growth in world population and an increasing demand in emerging economies. The vast majority of energy sources are actually derived from fossil. Chemical industry also uses fossil sources, primar…
Abstract Rotors are the systems allowing helicopters to flight, providing lift, and directional thrusts. Composite materials are nowadays widely used in rotor components construction and, namely, for blades and hubs. Typical applications are described. The evolution in the usage of fibrous composites from the simple s…
Abstract This article discusses vinyl ester resins that are produced by the esterification of a polyfunctional epoxy resin with an unsaturated monocarboxylic acid, usually methacrylic or acrylic acid, in the presence of a polymerization inhibitor, followed by the addition of a polymerizable diluent, usually styrene. T…
Abstract General composition, materials, and processes used to manufacture laminated wood composites are described in this article. Commonly used structural composite lumbers intended for structural and nonstructural applications, the mechanical properties of these types of laminated wood composites, and their perform…
Abstract Residual stresses can have important consequences for the manufacture and the resulting properties of polymeric, metallic, and ceramic matrix composite materials and components. Because of the different mechanical, thermal, and shrinkage properties of the fibers and matrices, as well as the anisotropy of the…
Abstract The present articles deals with polymeric matrixes for composite systems. Both thermoplastic and thermoset matrixes are discussed with reference to their structure‐property relationship, processing techniques, and application exploitation. The more recent modification strategies for tailoring of relevant matr…
Abstract This article summarizes the current status of the characterization methods for the strength properties of woven composites at cryogenic temperatures. The double‐notch and short‐beam shear test methods are examined for evaluation of the cryogenic interlaminar shear strength of woven glass fiber‐reinforced poly…
Abstract The degradation of polymer composites exposed to aggressive environmental conditions may result from several factors, such as loss of strength of reinforcing fibers by stress corrosion or water/solvent plasticization, matrix degradation by water/solvent sorption or chemical attack, and deterioration of fiber–…
Abstract A few unique aspects of composite structures are attained using a powder injection molding (PIM) approach. First, since the materials are not melted, it is possible combine different materials into a single component. Significant flexibility is possible by adjusting the size, size ratio, amount, and particle…
Abstract The review article gives historical insight to the developments in this area and where future activities should focus on as the industry moves forward with high temperature materials in a few select applications. Processing of the latest generation of partially fluorinated polyimides has improved significantl…
Abstract Carbon fibers have been widely used in fibre‐reinforced composites where strength‐to‐weight ratio is of upmost importance. In this article, a brief discussion of the production of PAN‐based carbon fibers is presented. The characterization of the physical and chemical properties of carbon fibers is discussed.…
Abstract The intention of the present article is to provide an overview of up‐to‐date understanding of matrix‐controlled failure modes. This subject covers distinct themes including failure criteria, micromechanics analysis, and theory of fracture mechanics. The effect of environmental conditions, rate dependency, del…
Abstract In this article, cost is defined and various components of cost to manufacture composite material products are presented. These components include material cost, labor cost, and tooling and capital cost. Factors constituting these components of cost are discussed in detail. Various costing methods being used…
Abstract This article aims primarily at providing basic understanding about the vibrational damping characteristics of polymer composite materials. The materials being looked at are continuous and discontinuous‐fiber‐reinforced, two‐phase as well as three‐phase; randomly oriented short‐fiber reinforced; laminated fibe…
