mazkur maqolada zamonaviy qurilish amaliyotida qo‘llanilayotgan kompozit armaturalarning (FRP — fiber reinforced polymer) fizik-mexanik va ekspluatatsion xususiyatlari chuqur ilmiy tahlil asosida o‘rganilgan. Kompozit armaturaning yuqori tortilish mustahkamligi, past zichligi, korroziyaga va agressiv muhitlarga chidamliligi, elektromagnit o‘tkazmaslik xususiyati kabi afzalliklari temir armatura bilan qiyosiy tahlil asosida baholangan. Shu bilan birga, uning elastiklik modulining nisbatan pastligi, mo‘rt buzilish xususiyati, yuqori harorat ta’sirida mexanik xossalarining keskin pasayishi hamda loyihalash me’yorlarining yetarli darajada shakllanmaganligi kabi kamchiliklari ham atroflicha ko‘rib chiqilgan.
