For the specific carbon and glass fibre based composite materials often referred to loosely as composites, see Fibre reinforced polymer. Composites are formed by combining materials together to form an overall structure with properties that differ from the sum of the individual components. A composite material also called a composition material or shortened to composite, which is the common name 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,1 which are known as Robotic Materials. Typical engineered composite materials include Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, racing car bodies, shower stalls, bathtubs, storage tanks, imitationgranite and cultured marblesinks and countertops. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments. HistoryeditThe earliest man made composite materials were straw and mud combined to form bricks for buildingconstruction. Ancient brick making was documented by Egyptian tomb paintingscitation needed. Wattle and daub is one of the oldest man made composite materials, at over 6. Concrete is also a composite material, and is used more than any other man made material in the world. As of 2. 00. 6update, about 7.

Woody plants, both true wood from trees and such plants as palms and bamboo, yield natural composites that were used prehistorically by mankind and are still used widely in construction and scaffolding. Plywood 3. 40. 0 BCcitation needed by the Ancient Mesopotamians gluing wood at different angles gives better properties than natural wood. Cartonnage layers of linen or papyrus soaked in plaster dates to the First Intermediate Period of Egypt c. BCcitation needed and was used for death masks. Cob material Mud Bricks, or Mud Walls, using mud clay with straw or gravel as a binder have been used for thousands of years. Concrete was described by Vitruvius, writing around 2. BC in his Ten Books on Architecture, distinguished types of aggregate appropriate for the preparation of lime mortars. For structural mortars, he recommended pozzolana, which were volcanic sands from the sandlike beds of Pozzuoli brownish yellow gray in colour near Naples and reddish brown at Rome. Vitruvius specifies a ratio of 1 part lime to 3 parts pozzolana for cements used in buildings and a 1 2 ratio of lime to pulvis Puteolanus for underwater work, essentially the same ratio mixed today for concrete used at sea. Natural cement stones, after burning, produced cements used in concretes from post Roman times into the 2. Portland cement. Papier mch, a composite of paper and glue, has been used for hundreds of years. The first artificial fibre reinforced plastic was bakelite which dates to 1. One of the most common and familiar composite is fibreglass, in which small glass fibre are embedded within a polymeric material normally an epoxy or polyester. The glass fibre is relatively strong and stiff but also brittle, whereas the polymer is ductile but also weak and flexible.

ExampleseditComposite Materialsedit. Concrete is a mixture of cement and aggregate, giving a robust, strong material that is very widely used. Plywood is used widely in construction. Composite sandwich structure panel used for testing at NASAConcrete is the most common artificial composite material of all and typically consists of loose stones aggregate held with a matrix of cement. Concrete is an inexpensive material, and will not compress or shatter even under quite a large compressive forcecitation needed. However, concrete cannot survive tensile loadingcitation neededi. Therefore, to give concrete the ability to resist being stretched, steel bars, which can resist high stretching forces, are often added to concrete to form reinforced concrete. Fibre reinforced polymers FRPs include carbon fibre reinforced polymerCFRP and glass reinforced plasticGRP. If classified by matrix then there are thermoplastic composites, short fibre thermoplastics, long fibre thermoplastics or long fibre reinforced thermoplastics.

Autodesk Concrete Building Structures Software Update' title='Autodesk Concrete Building Structures Software Update' />There are numerous thermoset composites, including paper composite panels. Zebronics Stem Mp3 Player User Manual'>Zebronics Stem Mp3 Player User Manual. Many advanced thermoset polymer matrix systems usually incorporate aramidfibre and carbon fibre in an epoxy resin matrix. Shape memory polymer composites are high performance composites, formulated using fibre or fabric reinforcement and shape memory polymer resin as the matrix. Since a shape memory polymer resin is used as the matrix, these composites have the ability to be easily manipulated into various configurations when they are heated above their activation temperatures and will exhibit high strength and stiffness at lower temperaturescitation needed. They can also be reheated and reshaped repeatedly without losing their material propertiescitation needed. These composites are ideal for applications such as lightweight, rigid, deployable structures rapid manufacturing and dynamic reinforcement. Progetto Stradale Completo Autocad 360. High strain composites are another type of high performance composites that are designed to perform in a high deformation setting and are often used in deployable systems where structural flexing is advantageous. Although high strain composites exhibit many similarities to shape memory polymers, their performance is generally dependent on the fibre layout as opposed to the resin content of the matrix. Composites can also use metal fibres reinforcing other metals, as in metal matrix composites MMC or ceramic matrix composites CMC, which includes bone hydroxyapatite reinforced with collagen fibres, cermet ceramic and metal and concrete. Ceramic matrix composites are built primarily for fracture toughness, not for strength. Another class of composite materials involve woven fabric composite consisting of longitudinal and transverse laced yarns. Woven fabric composites are flexible as they are in form of fabric. Organic matrixceramic aggregate composites include asphalt concrete, polymer concrete, mastic asphalt, mastic roller hybrid, dental composite, syntactic foam and mother of pearl. Chobham armour is a special type of composite armour used in military applications. Additionally, thermoplastic composite materials can be formulated with specific metal powders resulting in materials with a density range from 2 gcm to 1. The most common name for this type of material is high gravity compound HGC, although lead replacement is also used. These materials can be used in place of traditional materials such as aluminium, stainless steel, brass, bronze, copper, lead, and even tungsten in weighting, balancing for example, modifying the centre of gravity of a tennis racquet, vibration damping, and radiation shielding applications.
