Sekudlule iminyaka engaphezu kwemibili kwaqubuka i-COVID-19, kodwa umthelela walolu bhubhane kwezokukhiqiza usazwakala.Lonke uchungechunge lokuhlinzeka luphazamisekile, futhi imboni ye-fiberglass nayo ihlukile.Ukushoda kwezinhlanganisela ezifana ne-fiberglass, i-epoxy ne-polyester resins eNyakatho Melika kubangelwe ukubambezeleka kokuthunyelwa kwemikhumbi, ukukhuphuka kwezindleko zokuthumela kanye neziqukathi, ukunciphisa ukuthunyelwa kwesifunda okuvela e-China, kanye nesidingo esiphansi samakhasimende.
Noma kunezinkinga ze-supply chain, imakethe ye-fiberglass yase-US ikhule ngamaphesenti angu-10.8 ngo-2021, isidingo sikhuphuka safinyelela kumaphawundi ayizigidi eziyizinkulungwane ezingu-2.7, uma kuqhathaniswa namaphawundi ayizigidi eziyizinkulungwane ezingu-2.5 ngo-2020. izimakethe zezicelo zakhula kakhulu ngo-2021, ngenkathi imakethe ye-aerospace yehla.
Imboni ye-fiberglass e-United States izuze kakhulu ekukhuleni kwemboni yomoya ngo-2021. Lokhu kungenxa yokuthi amaphrojekthi amaningi omoya asebenza kusenesikhathi ukuze afanelekele ukukhululwa enteleni ngaphambi kokuba ikhredithi yentela yokukhiqiza iphelelwe yisikhathi ekupheleni konyaka.Njengengxenye yephakheji yosizo lwe-COVID-19, uhulumeni wase-US wandise i-PTC yakhe yafinyelela kumaphesenti angama-60 esamba sesikweletu samaphrojekthi kagesi omoya aqala ukwakhiwa ngoDisemba 31, 2021. U-Lucintel ulinganisela ukuthi imakethe yomoya yase-US izokhula ngo-8% ngo-2021, ngemva kokukhula okunamadijithi amabili ngo-2020.
Imakethe yezikebhe iphinde yakhula njengoba abathengi befuna izindawo zokungcebeleka zangaphandle eziphephile, ezingenazo inhlalo phakathi nalolu bhubhane, kanti imakethe yase-US Marine fiberglass ilinganiselwa ukuthi izokhula ngo-18% ngo-2021.
Mayelana nokuhlinzekwa kanye nesidingo embonini ye-fiberglass, izinga lokusebenzisa amandla ngo-2021 lenyuke lisuka ku-85% ngo-2020 laya ku-91% ngenxa yokwanda kokusetshenziswa kwe-fiberglass ezindaweni zokufaka izicelo.Umthamo wokukhiqiza we-fiberglass yomhlaba wonke ngo-2021 ungamaphawundi ayizigidi eziyizinkulungwane eziyi-12.9 (amathani angama-5,851,440).I-Lucintel ilindele ukuthi izitshalo ze-fiberglass zifinyelele ukusetshenziswa kwamandla angama-95% ngo-2022.
Eminyakeni eyi-15 kuye kwengama-20 ezayo, kuzoba nokuqanjwa okusha embonini ye-fiberglass, ikakhulukazi emicu yengilazi enamandla kakhulu, enemodulus ephezulu eqhudelana neminye imicu esebenza kakhulu efana ne-carbon fibre.Ukukhishwa kwekhabhoni engasindi kanye nokunciphisa kuzoba yizici ezimbili zemakethe ezihola emisha yesikhathi esizayo.
Isibonelo, izixazululo ezingasindi ziya ngokuya zibaluleke kakhulu emakethe yamandla omoya ngenxa yenani elikhulayo lezinjini zomoya zasolwandle, ukukhiqizwa kabusha kwama-turbine amadala, kanye nokufakwa kwezinjini zomoya ezinamandla kakhulu ezindaweni ezithola umoya wesivinini esikhulu.Kuyo yonke imakethe yomoya, usayizi omaphakathi wezinjini zomoya uyaqhubeka nokukhula, okwenza kube nesidingo sama-blade amakhulu nanamandla, okubuye kubhebhethekise isidingo sezinto ezilula neziqinile.Izinkampani ezimbalwa, ezihlanganisa i-Owens Corning kanye ne-China Megalithic, zenze imicu yengilazi ene-modulus ephezulu ukuze ihlangabezane nesidingo semakethe.
Inhlanganisela ye-Glass fiber reinforced iyingxenye ebalulekile yomkhakha wezikebhe futhi nobuchwepheshe obusha buyashintsha ubuso bemakethe.I-Moi Composites ithuthukise ubuchwepheshe obuthuthukisiwe be-3D ukukhiqiza i-MAMBO (Isitsha Sokukhiqiza Ugesi Esikhulayo).Isikebhe esiphrintiwe se-3D senziwe ngezinto ezihlanganisiwe ze-fiberglass eziqinisiwe ze-thermosetting futhi singamamitha angu-6.5 ubude.Ayinakho ukwahlukaniswa kwedekhi ye-hull futhi iveza umumo we-concave kanye ne-convex okungenakwenzeka ngezindlela ezivamile zokukhiqiza eziyinhlanganisela.Imboni yezikebhe nayo ithathe izinyathelo zokuthuthukisa ukusimama.I-RS Electric Boat ithuthukise isikebhe sokuqala esiqinile esiqinile esine-inflatable (RIB) esine-fiberglass kanye ne-carbon fiber egaywe kabusha njengezingxenye eziyinhloko zesakhiwo.
Sekukonke, izicelo ze-fiberglass ezimbonini ezahlukahlukene kulindeleke ukuthi zilulame emiphumeleni eyingozi yobhubhane lwe-COVID-19.Ezokuthutha, ezokwakha, zamapayipi kanye nezimakethe zamathangi, ikakhulukazi izikebhe, zizodlala indima ebalulekile ekubuyiseleni imakethe ye-fiberglass yase-US ezimeni zangaphambi kobhubhane.Sekuhlangene, imakethe ye-fiberglass yase-US kulindeleke ukuthi ikhule ngokuqinile ngo-2022 futhi ilulame ngokuphelele emthelela walo bhubhane.
