SMC composite zakuthupi ndi chidule cha Mapepala akamaumba pawiri. Zopangira zazikuluzikulu zimakhala ndi GF (ulusi wapadera), UP (unsaturated resin), zowonjezera zowonjezera, MD (filler) ndi zowonjezera zosiyanasiyana. Idawonekera koyamba kumayambiriro kwa zaka za m'ma 1960 ku Europe, mu 1965 kapena apo, United States ndi Japan adapanga izi. China chakumapeto kwa zaka za m'ma 80, kukhazikitsidwa kwa mizere yakunja yopangira ma SMC ndi njira zopangira. Ma composites a SMC ndi zinthu zake zopangidwa ndi SMC, zokhala ndi zida zabwino kwambiri zotchinjiriza magetsi, makina amakina, kukhazikika kwamafuta, kukana kwa dzimbiri kwamankhwala. Chifukwa chake kuchuluka kwa zinthu za SMC ndizofala.

Zophimba zitsime zimagwiritsidwa ntchito kuphimba misewu kapena zitsime zakuya kunyumba kuti anthu kapena zinthu zisagwe. Malinga ndi zinthuzo, zitha kugawidwa m'chivundikiro chazitsulo zachitsulo, chivundikiro champhamvu cha simenti ya simenti, chivundikiro cha manhole a utomoni ndi zina zotero. Nthawi zambiri kuzungulira. Itha kugwiritsidwa ntchito pa lamba wobiriwira, misewu, msewu wamagalimoto, doko, kanjira ndi zina zotero.

SMC kuumbidwa dzenje chivundikiro, mtundu watsopano wa zokongola mkulu-mphamvu dzenje chivundikiro, ntchito luso luso ndi akamaumba zida, ndi Unduna wa Zomangamanga, ndi National Center for Quality Kuyang'anira ndi Inspection of Construction Engineering, ndi katundu wolemetsa chivundikiro cha dzenje la kubala. mphamvu mpaka 400KN kapena kuposa, kwambiri kuposa muyezo dziko 240KN, ndipo pa nthawi yomweyo, pambuyo Center National kwa Quality Kuyang'anira ndi Inspection wa kuyezetsa FRP, index okalamba zosagwira kuposa muyezo dziko. Mankhwalawa angagwiritsidwe ntchito bwino kuyambira -40 ℃ mpaka 90 ℃. Moyo wautumiki ndi wautali kuposa chivundikiro cha chitsulo chachitsulo kwa zaka zoposa 5-10, ndipo ndondomeko yake ya ntchito imakwaniritsa ndikuposa zofunikira zapadziko lonse zazinthu zofanana, ndipo ndi chinthu chatsopano chomwe chimalowetsamo zophimba zamtundu wina. Amagwiritsidwa ntchito kwambiri m'matauni, mapaipi, njira, magetsi, madzi ndi ntchito zina.
