 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.
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.
The plastic is most often polyester or vinylester, but other plastics, like epoxy (GRE), are also sometimes used.

 Attachment of a stainless steel outerbody to a glass reinforced plastic inner body - Patent 4382626
In a structure comprising an inner molded glass reinforced plastic body and an outer shell of sheet material the sheet material is affixed to the body by at least one in-fill panel, the panel bonded to the body and the sheet material attached to the SMC panel by a plurality of self threading fasteners.
Damage to such finish is not always easy to repair and, in fact, in the case of an automobile where part of the GRP body might be damaged in a crash, the problem of a repair which restores the look of the body to what it originally was is somewhat difficult.
In the preferred embodiment, attachment of the stainless steel panels to the GRP body at most points is by means of stainless steel screws engaging rivnuts which are embedded in the GRP body.

 .::: SILENCERMARINE :::.
Silencers in GRP are made by the winding of continuous glass filament impregnated with resins around a spindle, using a technique borrowed from the aerospace sector.
GRP silencer is efficient even at temperatures exceeding 150°C, avoiding partial melting already at around 100°C, as usually happens with silencers made of plastic, maybe cheaper, but certainly less reliable.
They are also characterized by excellent properties of noise reduction and ensure a higher melting point than plastic silencers.

 Glass Reinforced Plastic Bore Casing for Large Diameter and Deep Bores
Stainless steel is approximately twice as expensive to purchase as GRP (glass fibre reinforced plastic) and twice as expensive to install due to factors such as the equipment required to handle the weight and the jointing costs.
Although at the conclusion of this successful project, development of GRP casing to its full potential is not complete, the aims of developing reliability and extending the size and depth range have been met.
The joints on the previously available GRP casing, however, were unreliable and unsafe to use in deeper pressure grouted bores particularly of larger diameter.

 Durability of AR Glass Fiber Reinforced Plastic Bars
The new advances in the field of materials science have resulted in the development of fiber reinforced plastic (FRP) materials that could potentially be used as bars in reinforced concrete structures.
In addition, 10 reinforced concrete beams were tested in flexure until failure, to examine the effects of exposure to concrete and deicing salts.
Since the development of reinforced concrete over a century ago, engineers have constantly struggled with the corrosion problem of steel reinforcement.

 Glass Reinforced Plastic (GRP) and Aluminium Bolted T-joints
Glass Reinforced Plastic (GRP) and aluminium bolted joints were chosen for investigation.
Joint failure was to be regarded as yielding of the aluminium or, for the GRP model, exceeding the failure strength of the composite material.
The GRP joint components consisted of a combination of 0.64mm thick unidirectional plies and 0.4mm thick biaxial woven plies to make up a nominal 12.16mm plate thickness.

 Glass Reinforced Plastics
Glass fibre reinforced plastic is a composite of a resilient durable resin with an immensely strong fibrous glass.
GRP is resistant to most acids, alkalis and hydrocarbons making it the ideal material for lining concrete tanks and bunds, pits and steel vessels.
GRP's excellent corrosion resistance at low and high temperature coupled with high tensile strength, low weight, ease of maintenance and competitive cost make it a superior material to stainless steel in many applications.

 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.

 William George Mitchell - GRP
GRP in the examples illustrated are produced by carving polyurethane sheets into the desired design - painting the finished design in liquid wax to prevent interaction between the polyurethane base and the polyester resin used to laminate the glass fibre sheets.
It is possible to execute work on a large or small scale, an example of an intricate design is the polished bronze GRP plaque depicting the London to Brighton Vintage Car Rally.
All examples were produced without a female mould, thus the design was produced back to front.

 Articles - Carbon fiber
Carbon fiber is most notably used to reinforce composite materials, particularly the class of materials known as graphite reinforced plastic.
By extension, it is also used informally to mean any composite material made with carbon filament; for more on that application, see graphite-reinforced plastic.
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.

 Analysis of a glass reinforced plastic arch for the U2 stage set
LUSAS was used to investigate stresses and forces in the GRP panels and coffin latches caused by the lifting process and, more critically, from a specified design wind loading of 130kmh (80mph) where suction effects tended to pull the joints between panels apart.
Self weight and wind loadcases were applied and a linear static analysis obtained stresses in the GRP panels and forces in the coffin latches for comparison with test results.
LUSAS QSL8 semiloof shell elements modelled the GRP panels and JL46 joint elements were used to model the coffin latches.

 Cambridge University Engineering Dept. - Structures Group
From the tests conducted, it was found that the GRP enclosure significantly enhanced the behaviour of the composite structure in global bending and torsion.
In addition, the punching shear capacity of the slab was found to be much greater than the code-predicted value, and well in excess of Ultimate HB wheel loading, probably due to enhancing membrane effects in the slab, which the codes do not recognise.
The short-term response of the slab to wheel loading was excellent, with no observed cracking or crushing of the concrete up to Ultimate HB loading, and the profiled steel sheeting successfully served as unpropped formwork to the wet concrete, and as bottom lateral reinforcement to the slab.
