Ubumaji nkawe - fiberglass!

Mu mpera za 1920, mugihe cy'ihungabana rikomeye muri Amerika, guverinoma yasohoye Itegeko ryiza: kubuza. Ibibujijwe byamaze imyaka 14, kandi abakora amacupa ya divayi bagize ibibazo umwe umwe. Isosiyete ya Owens Illinois niyo yari ikora amacupa manini manini muri Amerika muri kiriya gihe. Yashoboraga kureba gusa itanura ryibirahure bizimya. Muri iki gihe, umuntu wubahwa, wica imikino, byabaye hafi y itanura ryikirahure asanga ibirahuri byamazi yamenetse byajugunywe muburyo bwa fibre. Imikino isa nkaho Newton yakubiswe mumutwe na pome, kandifibreyabaye kuri stade yamateka kuva icyo gihe.
Umwaka umwe, Intambara ya Kabiri y'Isi Yose yaradutse, kandi ibikoresho bisanzwe byari bike. Mu rwego rwo guhaza ibikenewe mu ntambara ya gisirikare, fibre y'ibirahure yabaye umusimbura.
Abantu bagiye basanga buhoro buhoro ibi bikoresho bifite ibyiza byinshi - uburemere bworoshye, imbaraga nyinshi, kubika neza, kubika ubushyuhe no kubika ubushyuhe. Kubwibyo, tanks, indege, intwaro, ikoti ryamasasu nibindi byose ukoreshe fibre yibirahure.
Fibreni shyashyaibikoresho bitari ubutare, ikozwe mumabuye y'agaciro nka kaolin, pyrophyllite, umucanga wa quartz na hekeste binyuze munzira nyinshi nko gushonga ubushyuhe bwo hejuru, gushushanya insinga no kuzunguruka ukurikije formula imwe. Diameter yacyo ya monofilament iri hagati ya microne nyinshi na microne zirenga 20, ibyo bikaba bihwanye na 1 / 20-1 / 5 byumusatsi. Buri bundle ya fibre ibanziriza igizwe na magana cyangwa ibihumbi bya monofilaments.

Inganda zikora ibirahuri by’Ubushinwa zazamutse mu 1958. Nyuma y’imyaka 60 y’iterambere, mbere y’ivugurura no gufungura, byibanze cyane cyane mu ngabo z’igihugu ndetse n’inganda za gisirikare, hanyuma bihinduka imikoreshereze y’abaturage, kandi bigera ku iterambere ryihuse.
