vermiculite and actinolite. All types of fibrous silicate minerals belonging to asbestos family are composed of long, thin crystals, each one composed of a multitude of microscopic fibrils that are easily released into atmosphere. Their inhalation triggers lung health conditions including mesothelioma, asbestosis and cancer, see [1]. For such reasons composites with asbestos are completely banned in many countries. One characteristic sample of chrysotile asbestos from the biggest asbestos mine in the world – Jeffrey Mine, Quebec, Canada, is shown in **Figure 2**. Chrysotile asbestos belongs to the family of serpentine minerals.
