Zomwe zimalimbitsa ndi mafupa othandizira azinthu za FRP, zomwe zimatsimikizira zomwe zimapangidwira. Kugwiritsiridwa ntchito kwa zinthu zolimbikitsira kumakhalanso ndi zotsatira zina pa kuchepetsa kuchepa kwa mankhwala ndi kuonjezera kutentha kwa kutentha kwa kutentha ndi mphamvu yochepa ya kutentha.

Popanga zinthu za FRP, kusankha kwa zida zolimbikitsira kuyenera kuganizira mozama momwe zimapangidwira, chifukwa mtundu, njira yoyika ndi zomwe zili muzinthu zolimbikitsira zimakhudza kwambiri magwiridwe antchito azinthu za FRP, ndipo zimatsimikizira mphamvu zamakina ndi zotanuka modulus ya zinthu za FRP. Magwiridwe azinthu zopangidwa ndi pultruded pogwiritsa ntchito zida zolimbikitsira zosiyanasiyana ndizosiyana.

Kuonjezera apo, pokwaniritsa zofunikira zogwirira ntchito pakupanga mapangidwe, mtengowo uyenera kuganiziridwanso, ndipo zipangizo zochepetsera zotsika mtengo ziyenera kusankhidwa momwe zingathere. Nthawi zambiri, kuzungulira kosapindika kwa ulusi wa magalasi kumakhala kotsika mtengo kuposa nsalu za ulusi; mtengo wakumva ndi wotsika kuposa wansalu, ndipo kusakwanira ndikwabwino. , koma mphamvu ili yochepa; ulusi wa alkali ndi wotsika mtengo kuposa ulusi wopanda alkali, koma momwe zinthu za alkali zimachulukira, kukana kwake kwa alkali, kukana dzimbiri, ndi mphamvu zamagetsi zimachepa.
