Ungawabumba kanjani ama-thermoplastics aqiniswe ngefayibha ende?

2. Izingxenye kanye nomklamo wesikhunta
Izingxenye ezinhle kanye nomklamo wesikhunta nakho kunenzuzo ekugcineni ubude be-fiber ye-LFRT.Ukuqeda amakhona acijile emaphethelweni athile (okuhlanganisa izimbambo, abaphathi, nezinye izici) kungagwema ingcindezi engadingekile engxenyeni ebunjiwe futhi kunciphise ukugqokwa kwefayibha.
Izingxenye zizosebenzisa idizayini yodonga lokuzilibazisa ngokuqina kodonga olufanayo.Ukwehluka okukhulu kokuqina kodonga kungaholela ekugcwalisweni okungahambisani kanye nokuma kwefiber okungafuneki engxenyeni.Lapho kufanele kube kushubile noma kube mncane, izinguquko ezingazelelwe ekujikeni kwezindonga kufanele zigwenywe ukuze kugwenywe ukwakheka kwezindawo ezigunda kakhulu ezingase zilimaze imicu futhi zibe umthombo wokugxilisa ingqondo.Ngokuvamile zama ukuvula isango odongeni obukhulu futhi ugeleze engxenyeni encane, ugcine ukuphela kokugcwalisa engxenyeni encane.
Umgomo ojwayelekile wokuklama ipulasitiki omuhle uphakamisa ukuthi ukugcina ukujiya kodonga kungaphansi kuka-4mm (0.160in) kuzothuthukisa ukugeleza okuhle nokufanayo futhi kunciphise amathuba okuba nezintuba nama-voids.Kuzinhlanganisela ze-LFRT, ukujiya kodonga olungcono kakhulu kuvamise ukuthi kube ngu-3mm (0.120in), kanti ukujiya okuncane kakhulu kungu-2mm (0.080in).Lapho ubukhulu bodonga bungaphansi kuka-2mm, amathuba okuphuka kwefayibha ngemva kokuba impahla ingene esikhunjini ayanda.
Ingxenye iyisici esisodwa kuphela sokuklama, futhi kubalulekile ukucabangela ukuthi impahla ingena kanjani ekubunjeni.Lapho abagijimi namasango beqondisa impahla emgodini, uma kungekho umklamo olungile, umonakalo omkhulu we-fiber uzokwenzeka kulezi zindawo.
Lapho uklama isikhunta sokwenza izinhlanganisela ze-LFRT, umgijimi oyindilinga ngokugcwele ungcono kakhulu, futhi ububanzi bawo obuncane bungu-5.5mm (0.250in).Ngaphandle kwabagijimi abagcwele i-fillet, noma yiziphi ezinye izinhlobo zabagijimi zizoba namakhona abukhali, okuzokwandisa ukucindezeleka ngesikhathi senqubo yokubumba futhi abhubhise umphumela wokuqinisa we-glass fiber.Amasistimu womgijimi oshisayo anabagijimi abavulekile ayamukeleka.
Ubukhulu obuncane besango kufanele bube ngu-2mm (0.080in).Uma kungenzeka, thola isango onqenqemeni olungavimbeli ukugeleza kwento engena emgodini.Isango elingaphezulu kwengxenye lizodinga ukujikeleza ngo-90 ° ukuvimbela ukuphuka kwe-fiber nokunciphisa izakhiwo zemishini.
Okokugcina, qaphela indawo yomugqa wokuhlanganisa futhi wazi ukuthi zithinta kanjani indawo lapho ingxenye ingaphansi komthwalo (noma ingcindezi) ngesikhathi sokusetshenziswa.Umugqa wokuhlanganisa kufanele uhanjiswe endaweni lapho izinga lokucindezeleka lilindeleke ukuba libe phansi ngokuhlelwa okunengqondo kwesango.
Ukuhlaziywa kokugcwalisa isikhunta ngekhompyutha kungasiza ekunqumeni ukuthi le migqa yokushisela izotholakala kuphi.I-Structural finite element analysis (FEA) ingasetshenziswa ukuqhathanisa indawo yokucindezelwa okuphezulu nendawo yomugqa wokuhlangana onqunywe ekuhlaziyeni kokugcwalisa isikhunta.
Kumele kuqashelwe ukuthi lezi zingxenye kanye nemiklamo yesikhunta yiziphakamiso kuphela.Kunezibonelo eziningi zezingxenye ezinezindonga ezincane, ukujiya kwezindonga ezihlukene, nezici ezintekenteke noma ezinhle.Ukusebenza okuhle kufinyelelwa kusetshenziswa izinhlanganisela ze-LFRT.Kodwa-ke, uma uqhubeka uchezuka kulezi zincomo, kuzothatha isikhathi nomzamo owengeziwe ukuze uqinisekise ukuthi izinzuzo ezigcwele zobuchwepheshe befayibha ende ziyafezeka.
