Abstract: We consider questions connected with strength properties of continuous fibers from basalt, carbon and fibreglass under the influence of hostile alkaline $\rm KOH$; environment in researches were carried out on plaits, having 4000 threads of continuous fiber. The influence of hostile environment on strength properties of fiber and on its structure of surface layer is shown.

Keywords: basalt, glass, carbon, alkali, fiber, thread, plait, strength, composite, armature, building.
