A cikin 'yan shekarun nan, an yi amfani da shi sosai a sararin samaniya, ci gaban teku, jiragen ruwa, manyan motocin dogo, da dai sauransu. Saboda nauyinsa mai sauƙi, juriya na lalata, ƙarfin zafin jiki, da ƙarfin gaske, ya taka muhimmiyar rawa a cikin mutane da yawa. filayen, maye gurbin Yawancin kayan gargajiya.
A halin yanzu, gilashin fiber da carbon fiber composite kayan suna taka rawar gani sosai a fagen ginin jirgi.
1.0 Aikace-aikace a cikin jiragen ruwa
An fara amfani da kayan haɗin gwiwar a cikin jiragen ruwa a tsakiyar 1960s, da farko don ɗakunan ajiya a kan kwalekwalen sintiri. A cikin 1970s, babban tsarin ma'adinai kuma ya fara amfani da kayan haɗin gwiwa. A cikin 1990s, an yi amfani da kayan haɗin gwiwar gabaɗaya zuwa cikakkiyar mast da tsarin firikwensin (AEM/S) na jiragen ruwa. Idan aka kwatanta da kayan gini na jirgin ruwa na gargajiya, kayan haɗin gwiwar suna da kyawawan kaddarorin inji kuma ana amfani da su don kera ƙwanƙwasa. Suna da haske a cikin nauyi kuma suna da karin makamashi, kuma tsarin masana'antu yana da sauƙi. Aikace-aikacen kayan haɗin gwiwa a cikin jiragen ruwa ba kawai yana samun raguwar nauyi ba, har ma yana haɓaka radar infrared Stealth da sauran ayyuka.

1.1 Gilashin fiber
Ƙarfin gilashin fiber mai ƙarfi yana da halaye na ƙarfin ƙarfi mai ƙarfi, matsakaicin ƙarfin ƙarfin ƙarfi, juriya mai kyau mai ƙarfi, kwanciyar hankali mai kyau na sinadarai, juriya mai kyau, juriya mai zafi, da dai sauransu Ana iya amfani da harsashi mai zurfi na ruwa, sulke mai hana harsashi, jiragen ruwa. , manyan tasoshin ruwa da propellers, da dai sauransu. Sojojin ruwa na Amurka sun yi amfani da kayyakin kayyaki wajen kera manyan jiragen ruwa da wuri, kuma adadin jiragen da aka sanye da kayan gini su ma sun fi girma.
An fara amfani da ƙaƙƙarfan ƙaƙƙarfan tsarin jirgin ruwan sojojin ruwa na Amurka don ma'adinai. Tsarin filastik ne wanda aka ƙarfafa duka-gilashi. Shi ne mafi girma duka-gilashi haƙar maƙarƙashiya a duniya. Yana da babban tauri, ba shi da halaye masu karyewa, kuma yana da kyakkyawan aiki lokacin da yake jure tasirin fashewar ruwa. .
1.2 Carbon fiber
Aiwatar da matsuguni masu ƙarfi na carbon fiber akan jiragen ruwa a hankali yana fitowa a hankali. Dukkanin jirgin ruwan na Navy's corvettes na Yaren mutanen Sweden an yi shi ne da kayan haɗin gwiwa, yana samun babban aiki na ɓoyewa da rage nauyi da kashi 30%. Filin maganadisu na dukkan jirgin "Visby" yana da ƙasa sosai, wanda zai iya guje wa yawancin radars da tsarin sonar na ci gaba (ciki har da hoto na thermal), cimma tasirin sata. Yana da ayyuka na musamman na rage nauyi, radar da infrared ninki biyu.
Hakanan za'a iya amfani da abubuwan haɗin fiber na carbon a wasu bangarorin jirgin. Alal misali, ana iya amfani da shi azaman mai daɗaɗɗen shafting a cikin tsarin motsa jiki don rage tasirin girgizawa da hayaniyar ƙwanƙwasa, kuma ana amfani dashi mafi yawa a cikin jiragen bincike da jiragen ruwa masu sauri. Ana iya amfani da shi azaman tuƙi a cikin injuna da kayan aiki, wasu na'urori na musamman na inji da tsarin bututu, da dai sauransu. Bugu da ƙari, igiyoyin fiber carbon fiber masu ƙarfi kuma ana amfani da su sosai a cikin igiyoyin jiragen ruwa na ruwa da sauran kayan soja.
Ana amfani da kayan haɗin fiber na carbon fiber a cikin wasu aikace-aikacen jiragen ruwa, irin su propellers da propulsion shafting a kan tsarin motsa jiki, don rage tasirin girgizawa da hayaniyar ƙwanƙwasa, kuma galibi ana amfani da su don bincikar jiragen ruwa da jiragen ruwa masu sauri.

2.0 Jiragen ruwa na farar hula
Babban jirgin ruwa mai saukar ungulu, kwandon jirgi da bene an lullube shi da carbon fiber/epoxy resin, hull ɗin yana da tsayin mita 60, amma jimlar nauyin 210t kawai. Carbon fiber catamaran da aka gina a Poland yana amfani da vinyl ester resin sandwich composites, kumfa PVC da abubuwan fiber carbon. Mast da albarku duk nau'ikan fiber carbon ne na al'ada, kuma ɓangaren ƙwanƙwasa kawai an yi shi da fiberglass. Nauyin shine kawai 45t. Yana da halaye na saurin sauri da ƙarancin amfani da man fetur.
Bugu da ƙari, ana iya amfani da kayan fiber na carbon zuwa fatunan kayan aiki da eriya na jiragen ruwa, rudders, da ingantattun sifofi kamar bene, ɗakuna, da manyan kantuna.
Gabaɗaya magana, aikace-aikacen fiber carbon a cikin filin ruwa ya fara da ɗan lokaci kaɗan. A nan gaba, tare da haɓaka fasahar kayan haɗin gwiwa, haɓaka aikin sojan ruwa da haɓaka albarkatun ruwa, gami da ƙarfafa ƙarfin ƙirar kayan aiki, buƙatun fiber carbon da kayan haɗin gwiwar za su ƙaru. bunƙasa.
