According to the reinforcement material the following groups of Polymer Matrix Composites (PMC) are used: matrix, which can improve the bulk properties especially those of polymer-rich regions and introduce new functions, such as electrical, thermal and shielding, in composites having reinforcement at other scales, such as fibre reinforced polymer (FRP) composites. The SMC composites used in the automotive industry are randomly oriented discontinuous E-glass fiber composites in a thermoset matrix. Polymer Matrix Composites are very popular due to their low cost and simple fabrication methods. Two types of polymers are used as matrix materials for fabrication composites: Thermosets (epoxies, phenolics) and Thermoplastics (Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), polypropylene, nylon, acrylics).

The fibers and the matrix both can consist of any ceramic material, whereby carbon and carbon fibers can also be regarded as a ceramic material. Ceramic Matrix Composites Ceramic matrix composites may be classified into two categories. °C) −1), 1 ceramic fillers are added to these composites. 15.1).Because of their multiformity, their mechanical properties can be readily tailored (Table 15.1). Composite Materials Composite materials are materials that feature “microstructures”that are composed of two or more materials. Also known as FRP – Fibre Reinforced Polymers (or Plastics) – these materials use a polymer-based resin as the matrix, and a variety of fibres such as glass, carbon and aramid as the reinforcement. The term organic matrix composite is generally assumed to include two classes of composites, namely Polymer Matrix Composites (PMCs) and carbon matrix composites commonly referred to as carbon-carbon composites. The primary function of fibre reinforcement is to carry load along the length of the fiber and to provide strength and stiffness in one direction. Fibers, matrices and fillers.

NPTEL provides E-learning through online Web and Video courses various streams. Derived from its name, meaning many repeating units, polymers are often made up of branches of carbon and hydrogen chemically linked together to make a chain. The processing of polymer matrix composites does not involve high temperature and pressure and hence the equipments required are simpler. The most important inorganic non-metallic matrix composite materials are ceramic matrix composites (CMC’s) and carbon-based composite materials such as C/C composite materials. Polymer composites have enjoyed widespread use in the construction industry for many years in non-critical applications such as baths and vanities, cladding, decoration and finishing. There are several fracture modes in polymer composites such as delamination or interlaminar fracture, matrix cracking or intralaminar fracture, matrix-fiber debonding, fiber breaking, fiber pullout etc [3]. FRP represents a class of materials that falls into a category referred to as composite materials. • Continuous glass filaments in a polymer matrix • Strength due to fibers • Polymer simply holds them in place Influence of fiber materials, orientation, concentration, length, etc. Straw-reinforced clay may be considered as one of the first manmade composite materials. environments.

In the 90s the term polymer composite … Volume 1 of the Handbook, titled, “Polymer Matrix Composites Guidelines for Characterization of Structural Materials,” includes detailed discussions on a variety of composite test methods. Therefore, a polymer nanocomposite is a composite where filler and bulk polymer are minor components, and the interfacial polymer is the component that dictates material properties. 9. wich structures fabricated using polymer matrix composites have been explored since early 1980s. Composites comprise carbon fibre and polymer matrix resin. The matrix binds the fiber reinforcement, transfers loads between fibers, gives the composite component its net shape and determines its surface quality. Reinforcements for metal matrix composites have a manifold demand profile, which is determined by production and processing and by the matrix system of the composite material. Chapter 15 - Sandwich Composites 132 Sandwich materials have thin layers of a facing material joined to a lightweight filler material, such as a polymer foam.Neither the filler nor the facing material is strong or rigid, but the composite possesses both properties. Decrease weight without sacrificing strength (hollow glass sphere + polymer composite).

Polymer matrix composites are defined as materials comprising a matrix polymer and inclusions within that matrix polymer. A composite material typically consists of relatively strong, stiff fibres in a tough resin matrix. The cost of either company launching a new small composite plane would exceed $130bn (capital + work in progress + disruption to sales). Polymers (also known as plastics or resins) are far more popular than other two matrix materials, namely, metals and ceramics.
