 Encyclopedia: Fibre reinforced plastic
Fibre reinforced plastic (FRP) is a composite material comprising a polymer matrix reinforced with fibres usually of glass, carbon, or aramid (and in the case of Duroplast even cotton or wool) and is commonly used in aerospace, automotive and marine industries.
Fibre reinforced plastic (FRP) is a composite material comprising a polymer matrix reinforced with fibres usually of glass, carbon, or aramid and is commonly used in aerospace, automotive and marine industries.
Reinforced carbon-carbon (RCC) consists of carbon fibre-reinforced graphite, and is used structurally in high-temperature applications, such as the nose cone and leading edges of the space shuttle.

 Glass-reinforced plastic - Wikipedia, the free encyclopedia
Glass-reinforced plastic (GRP), is a composite material or fibre reinforced plastic made of a plastic reinforced by fine fibers made of glass.
Sailplanes have been built almost exclusively of reinforced plastic since the mid-1960s, with carbon, aramid and other fibres taking the place of glass in modern competition sailplanes, and with extensive use of high strength rovings.
Like graphite-reinforced plastic, the composite material is commonly referred to by the name of its reinforcing fibers (fiberglass), an example of part-for-whole metonymy.

 Fibre reinforced plastic structures and method and apparatus for producing same - Patent 4417937
Fibre reinforced plastic materials are currently finding wide application in the production of various structures such as panels, hoods, doors, tanks, boats and pipes which require such features as corrosion resistance and a high strength to weight ratio.
Fibre reinforced plastics products made by the technique described herein comprise a plurality of fibrous strands embedded in a matrix of plastics material, the fibrous strands being in the form of cut fibre lengths lying essentially parallel to one another.
Such structures are generally formed by placing resin coated high tensile strength filaments or fibres on suitable moulds or mandrels, and subsequently curing the resin and removing the fibre reinforced plastic part.

 Infostore: Demonstration Project for Recycling Waste Fibre Reinforced Plastic (FRP) Products
Fibre Reinforced Plastic (FRP), a thermosetting resin combined with inorganic material such as glass fibre, is multi-purpose and used widely in the production of bathtubs, ships, tanks, construction material, and automotive parts.
The mixed waste plastics were easy to handle when they were put in the kiln, and it was confirmed that they could be used as alternate materials and fuel for cement because they had little effect on kiln operation and cement quality.
They built a full-scale experimental waste-plastic crushing plant to verify crushing technology, calorie regulating technology, and noise and dust control methods.

 Concrete Reinforced with Fibre Reinforced Plastic
The durability is a function of both the resin and the fibre, while the amount and type of fibre are keys to determining the mechanical properties of FRPs.
The results, which apply to the particular resin and fibre combinations studied, show that the composite rods resist the alkaline environment well, with no significant degradation during the test period.
Part of a berthing facility at docks in Qatar was also constructed using FRP reinforcement, and another application was as reinforcement for the concrete fencing around a test facility for sensitive electrical equipment where conventional steel bars would have caused magnetic interference, (figure 1).

 Patents on Natural fibre Composites at Wageningen UR
Commodity plastics such as PP and (HD)PE are successfully reinforced by several natural fibres types such as flax, hemp, jute, kenaf and sisal; in addition reject streams from the pulp and paper/fibre processing industries turned out excellent cheap raw material as fillers in plastics.
When natural fibres are used it is important that during the extrusion process these fibres obtain and maintain a high aspect ratio so as to obtain a compounded material with mechanical properties comparable with those of materials containing glass fibres.
The design of this process is such that during the continuous mixing the natural fibres are opened up to elementary fibres with a high aspect ratio, which are homogeneously distributed in the polymeric melt.

 SP, a global manufacturer of advanced composite materials and technology solutions
They usually consist of a bulk material (the ‘matrix’) and a reinforcement, which is used primarily to increase the strength and stiffness of the matrix.
One of the earliest examples of a composite application was a mud hut, where mud was the matrix and straw was the reinforcement.
In its most basic form, a composite material is a combination of at least two elements working together to produce material properties that are different from the properties of those elements on their own.
