Chimiro chakaumbwa chinogona kugadzirwa nemaitiro ekugadzira.Iyo matrix-yakaputirwa fiber inopa yakakwana uye yakananga chimiro chechinhu, uye inodzivirira iyo fiber kubva pakuipa nekuda kwezvakatipoteredza pesvedzero, uye inoitawo sebhiriji kuendesa kushushikana pakati pemafibhi;nepo faibha inotakura yakawanda yesimba rekunze neayo akanakisa mechaniki zvivakwa uye inogona kupfuura Iyo chaiyo kurongeka kunoita mabasa akasiyana.Nekuda kwekudzikira kwayo uye kusimba kwepamusoro, fiber yekudyara inogona kuvandudza michina zvivakwa uye kuchengetedza yakaderera density painogadzirwa kuita FRP macomposites.Pamusoro pezvo, mafiibhi ekudyara anowanzo kudyara maseru aggregates, uye mapako uye maburi arimo anogona kuunza yakanakisa kupisa kupisa zvivakwa kune izvo.Pamberi pesimba rekunze (zvakadai sekudengenyeka), inobatsirawo kubva kune porosity yayo, iyo inobvumira simba kuti rikurumidze kupera.Uyezve, iyo yakakwana yekugadzira nzira yekudyara fiber inoburitsa kusvibiswa kushoma uye inoshandisa mashoma makemikari, ine yakaderera tembiricha yekushanda, ine mukana wekushomeka kwesimba rekushandisa, uye dhigirii rekupfeka kwemechini panguva yekugadziriswa zvakare yakaderera;uyezve, chirimwa faibha yakasikwa Renewable hunhu, inoenderera kugadzirwa inogona kuwanikwa pasi pekutonga kwakanaka uye kutonga.Nekubatsirwa kwehunyanzvi hwemazuva ano, kuparara uye kushorwa kwemamiriro ekunze kwezvinhu zvakadzorwa zvakanaka, kuitira kuti zvigone kuomeswa mushure mehupenyu hwechigadzirwa, pasina kukonzera kuunganidzwa kwemarara, uye kabhoni inoburitswa nekuora inotorwawo kubva pakukura kwekutanga.Iyo carbon source mumhepo inogona kunge isina kabhoni.
