The inorganic fibers are constituted mainly by inorganic chemicals, based on natural elements such as carbon, silicon and boron, that, in general, after receiving treatment at elevated temperatures are transformed into fibers.
Inorganic fibers, also sometimes dubbed high performance fibers or super-fibers, have characteristics and properties that differ from other non-natural fibers and therefore rarely find applications in the field of conventional textiles.
Effectively, these fibers have general characteristics as high thermal and mechanical resistance, which makes them especially in engineering solutions applied in many cases in combination with other materials – composites.
In these applications, they compete normally with conventional materials, replacing them often due to their ease of processing, thermal resistance, resistance to chemical agents and especially due to the excellent weight/mechanical properties correlation.
In general, the inorganic fibers are difficult to process by conventional textile techniques, such as weaving or knitting, due to the fact that easily break in flexure (weak), presenting low elongation at break and possess high coefficients of friction with metals , forcing many times to its surface lubrication.
