Particle reinforced metal matrix composites are playing a vital role in many applications, such as aerospace, aviation and automotive industry. According to production process the particle shapes vary with particle size, particle sphericity and weight fraction of particles with in composites structure. The preset work aims to examine the relationship between the mechanical behavior and composite structure of silicon carbide (SiC) particle reinforced aluminium matrix composite. Mechanical behavior testing was carried out on samples of SiC/Al composites of varying weight fractions by producing the composite specimen by stir casting production process. The particle size of SiC was estimated by measuring from the Scanning Electron Microscope (SEM) image of supplier using webplotdigitizer. Numerical simulation was carried out to generate SiC/Al composite and mechanical behavior was estimated by considering Representative Volume Element (RVE) of SiC/Al composite. The simulation was carried out using a recent software called DIGIMAT which is a non-linear multi-scale material and structural modeling platform. The simulations were carried out for different weight fractions of SiC/Al composites. Elastoplastic material properties, strengthened matrix properties and particle-matrix bonding behavior are introduced to simulate the mechanical behaviors of SiC/Al composites. The parameters like enough fine meshes, reasonable loads and proper boundary conditions were established to enhance the accuracy and reduce the computing cost. The numerical and experimental results were well corroborated. The work makes an effective attempt to establish the relationship between the actual composites structure and mechanical behaviours within the particle reinforced metal matrix composites.

A self-healing fiber-reinforced structural polymer matrix composite material is demonstrated. In the composite, a microencapsulated healing agent and a solid chemical catalyst are dispersed within the polymer matrix phase. Healing is triggered by crack propagation through the microcapsules, which then release the healing agent into the crack plane. Subsequent exposure of the healing agent to the chemical catalyst initiates polymerization and bonding of the crack faces. Self-healing (autonomic healing) is demonstrated on width-tapered double cantilever beam fracture specimens in which a mid-plane delamination is introduced and then allowed to heal. Autonomic healing at room temperature yields as much as 45% recovery of virgin interlaminar fracture toughness, while healing at 80 8C increases the recovery to over 80%.

Advanced fibre-reinforced plastic (FRP) composite materials are ideal for structural applications where high stiffness-to-weight and strength-to-weight ratios are required. Such materials are inherently heterogeneous. Typically, they are made of a polymeric matrix reinforced by continuous or discontinuous fibres. The wide range of fibre and matrix types along with the multiple fibre arrangement possibilities makes FRP composites behave in a more complex way than conventional metals. As a result, they not only have a strong anisotropic behaviour but also predicting failure can be challenging. In this webinar, we will explain how to predict intra-laminar failure in long continuous FRP composite structures subjected to real life multiaxial loading conditions. We will demonstrate how to select the right criterion for detecting critical regions where failure is likely to occur. We will also show how to accurately predict margin to failure.

What is COMPOSITE CONSTRUCTION? What does COMPOSITE CONSTRUCTION mean? COMPOSITE CONSTRUCTION meaning - COMPOSITE CONSTRUCTION definition - COMPOSITE CONSTRUCTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Composite construction is a generic term to describe any building construction involving multiple dissimilar materials. Composite construction is often used in building aircraft, watercraft, and building construction. There are several reasons to use composite materials including increased strength, aesthetics, and environmental sustainability. In structural engineering, composite construction exists when two different materials are bound together so strongly that they act together as a single unit from a structural point of view. When this occurs, it is called composite action. One common example involves steel beams supporting concrete floor slabs. If the beam is not connected firmly to the slab, then the slab transfers all of its weight to the beam and the slab contributes nothing to the load carrying capability of the beam. However, if the slab is connected positively to the beam with studs, then a portion of the slab can be assumed to act compositely with the beam. In effect, this composite creates a larger and stronger beam than would be provided by the steel beam alone. The structural engineer may calculate a transformed section as one step in analyzing the load carry capability of the composite beam. A flitch beam is a simple form of composite construction sometimes used in North American light frame construction. This occurs when a steel plate is sandwiched between two wood joists and bolted together. A flitch beam can typically support heavier loads over a longer span than an all-wood beam of the same cross section. The traditional decking material is pressure treated wood. The current material many contractors choose to use is composite decking. This material is typically made from wood-plastic composite or Fiberglass Reinforced Plastic (FRP). Such materials do not warp, crack, or split and are as versatile as traditional pressure treated wood. Composite decking is made through several different processes, and there are a multitude of sizes, shapes, and strengths available. Depending on the type of composite selected the decking materials can be used for a number of other construction projects including fences and sheds. In a composite steel deck, the dissimilar materials in question are steel and concrete. A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Additionally, composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load deflection in comparison to previous construction methods. Cement-polymer composites are being developed and tested as a replacement for traditional cement. The traditional cement used as stucco rapidly deteriorates. The deterioration causes the material to easily crack due to thermo-processes becoming permeable to water and no longer structurally sound. The United States Environmental Protection Agency in conjunction with Materials and Electrochemical Research Corporation tested a cement-polymer composite material consisting of crumb rubber made from recycled rubber tires and cement. It was found that 20% crumb rubber can be added to the cement mixture without affecting the appearance of the cement. This new material was tested for strength and durability using American Society for Testing and Materials (ASTM International) standards.

Introduction to composite materials… A composite material is also called a composition material or shortened to composite which is the common name. It is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons. Common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials. Typical engineered composite materials include mortars, concrete, Reinforced plastics, such as fiber-reinforced polymer, Metal composites and Ceramic composites such as composite ceramic and metal matrices. Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and countertops. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments.

"Interphase Chemical Mapping Of Carbon Fiber-epoxy Composites By Afm-ir Spectroscopy" The properties and performance of carbon fiber reinforced polymer matrix composites are highly influenced by the chemical interactions of the fiber/matrix interface region. Many researchers have hypothesized that the presence of carbon fibers in epoxy causes a chemical gradient to form around the fiber during the curing stage. However, the chemical makeup of the interphase region and how it influences composite behavior is yet to be fully understood. One of the obstacles has been the lack of experimental techniques available to chemically probe the interphase with sufficient resolution. High-resolution spectroscopy techniques recently developed to study biological processes at the cellular level also have significant potential for characterization of synthetic materials systems. Here, we apply atomic force microscopy based infrared (AFM-IR) spectroscopy to investigate the interphase region developed between carbon fibers and epoxy matrix in an aerospace-grade composite material. The working principle of the technique will be reviewed and key findings will be highlighted. AFM-IR spectra of the bulk matrix material are in excellent agreement with spectra collected by traditional FTIR in both the low wavenumber range (900-1700/cm) and in the high wavenumber range (more than 2500/cm). Chemical maps of the interphase region provide preliminary evidence for distinct variations in matrix chemistry near the fiber surface in comparison to bulk.

The range of structural composite materials on the market is vast but all are typically made of a polymeric matrix reinforced by continuous or discontinuous fibres. The wide variety of fibre and matrix types along with the multiple fibre arrangement possibilities makes FRP composites behave in a more complex way than conventional metals. Such materials are inherently heterogeneous and as a result, they not only have a strong anisotropic behaviour but also predicting failure can be challenging. Historically the solution has been to focus on experimental testing but the amount of testing on full size components can be significant. When combined with experimental test data derived from a pyramid of testing approach, the Composite Failure Analysis module in nCode DesignLife gives a method of exploring how the laminate design might influence the fatigue behaviour of composite components in service. In this 45-minute webinar, Dr. Peter Heyes - Technical Specialist at HBM Prenscia, will explain how to predict intra-laminar failure in long continuous FRP composite structures subjected to real life multiaxial loading conditions.
