Specific weight of fiber, properties, advantages, grades, table of values

Fiber is a material made from layers of base paper by impregnating them with a concentrated zinc chloride solution and pressing. Less often, a solution of calcium thiocyanate and sulfuric acid is used instead of zinc chloride. The raw material for fiber production is made from cellulose or bleached rag half-stuff. This type of material is produced in the form of rods, tubes and sheets with sizes from 0.1 to 76 mm. This material is easy to machine.

Table of the specific weight of fiber

The weight of this material depends on such a parameter as the specific weight of fiber. Since this material is complex, it is not possible to calculate its specific weight in field conditions. This procedure is carried out in special chemical laboratories. However, the average specific weight is known and is 1.28 g/cm³.

To make it easier to calculate such indicators as the weight of fiber and its specific weight, the table below shows these values, as well as other calculations for different systems of measurement.

Properties of fiber

Fiber is characterized by low density, but it has high strength. This material is elastic and impact-resistant. It has high abrasion resistance, excellent heat- and electrical-insulation properties, and is also resistant to the action of benzene, petroleum, ether, oils, alcohol and organic solvents. It also has good non-combustibility and resistance to splitting.

This type of material retains its properties in a temperature range from minus 40 to plus 120 degrees Celsius, while withstanding cooling to minus 80 degrees Celsius and restoring its properties after heating to room temperature.

Fiber is considered an environmentally friendly product.

Advantages of using fiber

Fiber is an excellent replacement for reinforcing mesh, which ultimately makes it possible to preserve the load-bearing capacity of concrete-type slabs while reducing the screed thickness. At the same time, the speed of work increases and the labor intensity of construction processes decreases.

The use of fiber significantly reduces carbon dioxide emissions into the environment, because this product is environmentally friendly, which, in turn, occurs due to the reduced use of metal in the structure.

The use of this material makes it possible to achieve the following characteristics:

• Excellent resistance to dynamic and static loads
• High crack resistance
• Good wear resistance and durability
• High strength
• High resistance of concrete to vibration

Fiber grades

Fiber grades depend on the field of application. This type of material is divided into the following types:

• FT grade fiber, technical fiber for creating insulating and structural parts for devices, machines and other machine-building products
• FE grade fiber, electrical fiber for manufacturing electrical-insulation parts and general-purpose industrial parts
• FP grade fiber, craft fiber for manufacturing containers, suitcases and other similar products
• FPK grade fiber, oxygen-resistant gasket fiber for creating parts and gaskets with high resistance to oxygen exposure
• KGF grade fiber, castor glycerin fiber for creating sealing-type parts used for connecting pipelines and metal-type structures
• PFS grade fiber, layered fiber plastic for creating insulating and structural parts used in mechanical engineering
