Carbon Basalt Multilayer PPR Pipe

Dear Partner
As you know,  we have begun to work on a new generation of pipe, we finished our testing and our supply and next step is to give you some further informations about the materials we use to better fit your needs.
Our pipes have two different generation fibers: Basalt and Carbon fiber. For that reason we would like to  first do a quick introduction for Basalt and carbon fibers.
Basalt
Basalt-FiberBasalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fiber and fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products.
Benefits of Basalt Fiber
• High chemical resistance, including to concentrated acids.
• High thermal resistance (thermo stability) and low flammability.
• Relatively high mechanical strength, abrasion resistance and elasticity.
• Low degradation of strength at temperatures as high as 900 degrees Fahrenheit.
• Tensile strength greater than same size steel mesh.
• High thermal and acoustic insulation properties.
• Excellent adhesion to polymer resins and rubbers.
• High electrical insulating properties.
• Renewable alternative to metal building materials.
• Ecologically clean and non-toxic to the end user.

Carbon (fiber)
Carbon-Fiber-PipeCarbon fiber, alternatively graphite fiber or CF, is a material consisting of fibers about 5–10 μm in diameter and composed mostly of carbon atoms.
To produce carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber as the crystal alignment gives the fiber high strength-to-volume ratio (making it strong for its size). Several thousand carbon fibers are bundled together to form a tow, which may be used by itself or woven into a fabric.
The properties of carbon fibers, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion, make them very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared to similar fibers, such as glass fibers or plastic fibers.
Carbon fibers are usually combined with other materials to form a composite. When combined with a plastic resin and wound or molded it forms carbon-fiber-reinforced polymer (often referred to as carbon fiber) which has a very high strength-to-weight ratio, and is extremely rigid although somewhat brittle. However, carbon fibers are also composited with other materials, such as with graphite to form carbon-carbon composites, which have a very high heat tolerance.
Benefits of Carbon Fiber Include:
•Stronger than steel
•Only 1/16th of an inch thick
•Lightweight and flexible
•No downtime
•70% lighter weight than steel, and 40% lighter weight than aluminumTDs
•High strength-to-weight ratio
•Highly corrosion resistant
•Application flexibility
•Low mass
•No excavating, bolting, or drilling!
•Abrasion-resistant
•Temperature-resistant
•Chemical-resistant, even to acids, alkalis, and solvents

Glass Fiber
Glass fiber (or glass fibre) is a material consisting of numerous extremely fine fibers of glass.
Glassmakers throughout history have experimented with glass fibers, but mass manufacture of glass fiber was only made possible with the invention of finer machine tooling. In 1893, Edward Drummond Libbey exhibited a dress at the World’s Columbian Exposition incorporating glass fibers with the diameter and texture of silk fibers. This was first worn by the popular stage actress of the time Georgia Cayvan. Glass fibers can also occur naturally, as Pele’s hair.
Glass fiber has roughly comparable mechanical properties to other fibers such as polymers and carbon fiber. Although not as strong or as rigid as carbon fiber or basalt fiber, it is much cheaper and significantly less brittle when used in composites. Glass fibers are therefore used as a reinforcing agent for many polymer products; to form a very strong and relatively lightweight fiber-reinforced polymer (FRP) composite material called glass-reinforced plastic (GRP), also popularly known as “fiberglass”. This structural material product contains little air, is more dense than glass wool, and is an especially good thermal insulator.
Glass Fiber
Glass is by far the most used fiber in reinforced plastic composites. In many industries it represents over 90% of the reinforcements used. Its main advantages are:
• Low cost
• High strength
• Light weight (relative to steel)GlassFiber
• High chemical resistance

The main disadvantages are:
• Low modulus (relative to other reinforcing fibers)
• Low fatigue resistance (relative to carbon fibers)
• High weight (relative to other reinforcing fibers)
• Highly abrasive when machined
• Susceptibility to stress corrosion
• Easy to break
