A low weight resistant porous glass fiber having physical chemical or biological properties

A low weight resistant porous glass fiber of type I is disclosed with a developed specific surface area of 5 times to 120 times the outer surface of a standard glass fiber, and a material having physical, chemical or biological reactive properties deposited on the developed surface area of said porous glass fiber. A low weight resistant porous glass fiber of type II is disclosed as well with a developed specific surface area of 20 times to 200 times the outer surface of a standard glass fiber. The developed surface of said porous glass fiber is covered with a material capable of being a support for receiving a material having physical, chemical or biological reactive properties, and a material having physical, chemical or biological reactive properties is deposited on the intermediate support material covering the porous glass fiber. Corresponding processes of preparation and various uses are described.
