Unidirectional carbon ribbons



Unidirectional carbon ribbon LR-STR-A is produced according to TU 1916-011-45680943-2011 (technical conditions) on the basis of domestic and foreign carbon braids. Various types of ribbons (based on carbon and aramid fibers and glass-reinforced fiber, combined) are available.

Properties:
— enhanced resistance of reinforced structures to impact and explosion loads;
— resistance to chemical substances and atmospheric factors;
— universality in application: units with different surface geometries (beams, columns, pillars, flues, walls) can be reinforced;
— easiness: the reinforcement system creates no additional load on the structure;
— minimum time and labor expenses for works;
— possibility to perform works without stopping exploitation of buildings or installations;
— no additional expenses or subsequent exploitation.

The carbon ribbon corresponds to requirements and values indicated in the table:
