Ngaphezu kweminyaka emibini sele idlulile oko kwaqhambuka i-COVID-19, kodwa impembelelo yobhubhane kwimveliso isavakala.Lonke ikhonkco lokubonelela liphazamisekile, kwaye ishishini le-fiberglass alikho ngaphandle.Ukunqongophala kwee-composites ezifana ne-fiberglass, i-epoxy kunye ne-polyester resins eNyakatho Melika kubangelwe ukulibaziseka kokuthunyelwa kwenqanawa, ukunyuka kweendleko zokuthumela kunye ne-container, ukunciphisa ukuthunyelwa kwemimandla evela e-China, kunye nemfuno ephantsi yabathengi.
Nokuba kukho imiba yonikezelo, imarike ye-fiberglass yase-US ikhule ngeepesenti ezili-10.8 ngo-2021, imfuno inyuke yaya kutsho kwi-2.7 yeebhiliyoni zeeponti, xa kuthelekiswa ne-2.5 yeebhiliyoni zeeponti ngo-2020. iimarike zezicelo zikhule kakhulu ngo-2021, ngelixa imakethi ye-aerospace inqabile.
Ishishini le-fiberglass e-United States lizuze kakhulu ekukhuleni kweshishini lomoya ngo-2021. Oku kungenxa yokuba iiprojekthi ezininzi zomoya zisebenza kwangethuba ukuze zifanelekele ukukhululwa kwirhafu phambi kokuba intengo yetyala yerhafu iphelelwe ekupheleni konyaka.Njengenxalenye yephakheji yoncedo lwe-COVID-19, urhulumente wase-US wandise i-PTC yakhe ukuya kuma-60 epesenti yetyala lilonke leeprojekthi zamandla omoya eziqala ukwakhiwa nge-31 kaDisemba, 2021. I-Lucintel iqikelela ukuba imakethi yomoya yase-US izakukhula nge-8% ngo-2021, emva kokukhula okuphindwe kabini ngo-2020.
Imakethi yesikhephe nayo ikhule njengoko abathengi befuna izinto zokuzonwabisa ezikhuselekileyo, ezingenantlalontle zangaphandle ngexesha lobhubhani, kunye ne-US Marine fiberglass imakethi eqikelelwa ukuba ikhule nge-18% ngo-2021.
Ngokuphathelele ukubonelela kunye nemfuno kwishishini le-fiberglass, izinga lokusetyenziswa kwamandla ngo-2021 linyuke ukusuka kwi-85% ngo-2020 ukuya kwi-91% ngenxa yokwanda kokusetyenziswa kwe-fiberglass kwiindawo zokuphela kwesicelo.I-Global fiberglass umthamo wokuvelisa kwi-2021 yi-12.9 yeebhiliyoni zeeponti (iitoni ezi-5,851,440).U-Lucintel ulindele ukuba izityalo ze-fiberglass zifikelele kwi-95% yokusetyenziswa kwamandla ngo-2022.
Kwiminyaka eyi-15 ukuya kwe-20 ezayo, kuya kubakho ukuqalwa kwezinto ezintsha kwishishini le-fiberglass, ngakumbi kumandla aphezulu, i-high-modulus fibers yeglasi ekhuphisanayo kunye nezinye iifiber ezisebenza kakhulu ezifana ne-carbon fiber.Ukukhanya okulula kunye nokunciphisa ukukhutshwa kwekhabhoni kuya kuba ngabaqhubi ababini beemarike abakhokelayo kwixesha elizayo.
Umzekelo, izisombululo ezikhaphukhaphu ziya zisibaluleka ngakumbi kwimarike yamandla omoya ngenxa yokukhula kwenani leeinjini zomoya ezikude nonxweme, ukuveliswa kwakhona kweeinjini zomoya ezindala, kunye nokufakelwa kwee turbines ezinomthamo ophezulu ngakumbi kwiindawo ezifumana umoya ohamba ngesantya esiphezulu.Kuyo yonke imarike yomoya, ubungakanani obuqhelekileyo beeinjini zomoya buyaqhubeka ukukhula, kuqhuba imfuno yeeblade ezinkulu nezinamandla, ezithi zona zifake amafutha kwimfuno yemathiriyeli ekhaphukhaphu nenamandla.Iinkampani ezininzi, kubandakanya i-Owens Corning kunye ne-China Megalithic, zenze iintsinga zeglasi eziphezulu zemodulus ukuhlangabezana nemfuno yemarike.
Imihlanganisela eyomeleziweyo yefayibha yeglasi yinxalenye ebalulekileyo yecandelo lokuhamba ngesikhephe kwaye itekhnoloji entsha iyabutshintsha ubuso bemarike.I-Moi Composites iphuhlise iteknoloji ye-3D ephezulu ukuvelisa i-MAMBO (i-Electric Incremental Manufacturing Vessel).Isikhitshane semoto esiprintiweyo se-3D senziwe nge-fiberglass eqhubekayo eyomelezwe imathiriyeli ehlanganisiweyo ye-thermosetting kwaye iyi-6.5 yeemitha ubude.Ayinalo ulwahlulo lwedekhi ye-hull kwaye ibonisa i-concave kunye ne-convex imilo engenakwenzeka ngeendlela eziqhelekileyo zokuvelisa izinto ezidibeneyo.Ishishini lephenyane lithathe amanyathelo okuphucula ukuzinza.I-RS Electric Boat iphuhlise isikhephe sokuqala sombane esine-inflatable (RIB) sokuqala esine-fiberglass kunye ne-carbon fibre esetyenzisiweyo njengezona nxalenye zesakhiwo.
Lilonke, izicelo ze-fiberglass kumashishini ahlukeneyo kulindeleke ukuba zibuyele kwiziphumo eziyingozi zobhubhani we-COVID-19.Uthutho, ulwakhiwo, imibhobho kunye neemarike zetanki, ngakumbi izikhephe, ziya kudlala indima ebalulekileyo ekubuyiseleni imarike ye-fiberglass yase-US kwiimeko zangaphambi kobhubhane.Ithathiwe kunye, imakethi ye-fiberglass yase-US kulindeleke ukuba ifezekise ukukhula olomeleleyo ngo-2022 kwaye iphinde iphile ngokupheleleyo kwimpembelelo yobhubhane.
