What is glass fiber reinforced plastic?

Glass fiber reinforced plastic, also known as GRP, is a stable material made of plastic and glass fiber.

Where can GRP be used?

The areas of application for GRP are diverse and can be used in industry as well as in the private sector.

What are the advantages of Fibrolux GRP products?

Our Fibrolux products are durable and lightweight, making them ideal for a wide range of applications. They are characterized by a number of advantages. These include corrosion resistance, electrical insulation, high temperature resistance and a host of other benefits.

What advantages does fiberglass offer over traditional materials such as steel or aluminum?

Fibrolux GRP products offer you high strength at a significantly lower weight compared to steel or aluminum. In addition, unlike metals, GRP is not susceptible to corrosion and is resistant to various chemical substances. Furthermore, our GRP products retain their mechanical properties even under extreme environmental conditions such as UV radiation, moisture and temperature fluctuations over a long period of time.

How can I process GRP?

A conventional metal saw is sufficient for sawing smaller quantities. For larger volumes, however, the use of a diamond-tipped saw blade is recommended. The diameter of the saw blades should be between 200 - 500 mm, depending on the wall thickness. Extraction is recommended for dry processing. Cutting speed 1800 to 3600 m/min.

For turning smaller quantities, standard equipment such as that used for conventional metalworking is sufficient. For larger quantities, however, carbide tools such as those used for brass or aluminum machining should be used. Water cooling is always advisable. Cutting speed as for brass or aluminum.

Hardened steel tools should be used for punching. However, the material thickness of the workpiece to be processed should not be greater than 10 mm. Max. Material thickness when punching = 10 mm

Threads should only be cut if the connection is not subjected to excessive tensile stress. The pull-out strength is around a third of that of metallic threads, but sufficient strength for many applications can be achieved with an exact fit and the use of adhesive. Tubular and trapezoidal threads enable better force transmission than metric threads

GRP can be bonded easily and firmly with polyurethane and epoxy resin-based adhesives. However, the instructions given should be observed.

1. Roughen the surface 2. Remove dust 3. Degrease with solvent 4. Follow the manufacturer's guidelines when applying the adhesive.

When riveting, the hole should be slightly larger than the rivet diameter. The use of adhesives to increase the bond strength is recommended. The use of adhesives increases the bond strength.

For lightly loaded connections, self-tapping screws are sufficient. Machine screws should be used for connections that are subject to heavy loads. The use of adhesives is also recommended when screwing to increase the bond strength.

The surface to be painted should be thoroughly cleaned with a solvent and degreased before applying the paint. We recommend a polyurethane-based lacquer system. The best painting results are achieved with 2-component PUR paints.

How can I bond GRP?

As glass fiber mats also essentially consist of polyester resin, vinyl ester resin and acrylic resin, the adhesive should also be selected according to the respective resin type of the component to be bonded. Consequently, resin adhesives with chemically and physically similar properties to the respective plastic base of the GRP are suitable as construction adhesives.

There are polyester resin adhesives and epoxy resin adhesives as well as formulations made of polyurethane or acrylate on the market. Dissolving adhesives are rather unsuitable. To bond GRP to metals such as aluminum, stainless steel or steel with high strength, 2-component construction adhesives based on acrylate or epoxy resin are suitable.

For example, 3M Scotch-Weld 7270 with a suitable epoxy or acrylate formulation and color indicator, which clearly indicates the curing status by changing color from yellow to green.

Reaction adhesives are suitable for bonding wood (painted, primed or coated) with glass fiber-reinforced thermosetting plastic. However, the different surface finishes affect the bonding properties. 3M Scotch-Weld DP 110, a fast-curing, clear 2-component construction adhesive based on epoxy resin, which also bonds GRP to metal and a variety of other plastics such as PC, rigid PVC and ABS, is recommended here.

Bonding GRP (duroplastic) to wood (untreated) or thermoplastic-duroplastic GRP combinations is possible with 3M Scotch-Weld DP 490, a viscoplastic black two-component construction adhesive based on epoxy resin with increased heat resistance and good ageing behavior.
