The glass fiber is a material used for the production of composite materials, advanced structural materials or in which different components are integrated together to produce a material for mechanical surprising.

The common experience tells us that glass is a monolithic brittle material. If instead it is spun to a diameter of order less than tenth of a millimeter loses its characteristic weakness to become a material with high mechanical strength.
This is because the fragility of glass is common due to the large number of defects that act as crystallization and micro areas of concentration of effort. On the contrary, the glass fiber does not present all these defects, which achieves high mechanical resistance.

We distinguish different types of fibers depending on their characteristics, on which their use.

The glass fibers are widely used in the production of structural composites in aerospace, marine, automotive, associated with different matrices such as polyamide or epoxy, but synthetic resins.

The Italian Klevers exploits for nearly 30 years the characteristics of glass fiber in the field of thermal and acoustic, producing and marketing products and fabricated with glass wool base.

The glass wool is produced resulting in fusion at a temperature between 1300-1500 ° C a mixture of glass and sand which is then converted to fiber, with the addition of a binder which increases the cohesion of the fibers themselves obtained this ligand is the key and the secret process of industrial production of glass wool. This fiber is then heated to about 200 ° C and subjected to calendering to give additional strength and stability. Finally, the glass wool is spun, carded, or cut the company rolls or panels and bobbin.
