Kodayake tsarin gyare-gyaren ajiya na gargajiya (FDM) yana da fa'ida ta asali wajen kera rikitattun sassa na tsari, abubuwan da aka ƙera ta amfani da wannan fasaha har yanzu suna da matsalolin ƙarancin ƙarfi da ƙarancin zafi.

Don ƙara ƙarfin samfurin, yin amfani da nauyin nauyi, kayan ƙarfafa ƙarfin fiber mai ƙarfi shine hanya mai mahimmanci. Wasu masu bincike sun gauraya yankakken zaruruwa cikin kayan guduro da sarrafa wayoyi masu ƙarfafa fiber don FDM. Ko da yake tsarin FDM na yau da kullun da aka gada ta irin wannan yankakken fiber-ƙarfafa wayoyi yana da fa'idar samar da hadaddun sassan geomorphic, haɓakar ƙarfin samfurin ba a bayyane yake ba, kuma ba zai iya biyan buƙatun ƙarfin da muke tsammani ba. . Idan aka kwatanta da yankakken kayan da aka ƙarfafa fiber, ci gaba da ƙarfafa kayan aikin fiber na iya ƙara ƙarfin samfurin sosai, amma saboda ci gaba da iyakancewar fiber, hanyar gyare-gyaren ba ta da ikon samar da sassan sassa masu rikitarwa.

Domin warware matsalar da aka ambata a sama na ci gaba da ƙarfafa gyare-gyaren fiber, masu bincike MY da YK daga makarantar sakandaren Jafananci sun ƙware a cikin ƙira da kera sabon nau'in bututun ƙarfe (Figure 1).

Ba kamar na al'ada ci gaba da fiber ƙarfafa kayan aiki, bututun ƙarfe yana amfani da na'urorin ciyarwa guda biyu don sarrafa ciyarwar ci gaba da fiber carbon fiber ƙarfafa thermoplastic waya da ƙarin guduro waya. Ci gaba da fiber ƙarfafa thermoplastic waya da ake amfani da su waya ce da aka yi da carbon fiber nannade PA6 tare da diamita na 0.3 mm, inda a cikinsa carbon fiber abun ciki na Vf ana sarrafa a 50%, da kuma ƙarin resin abu ne nailan 645. Guda guda. -Layer giciye sashe buga ta bututun ƙarfe aka nuna a cikin siffa 2. Ƙananan ɓangare na daya Layer ne ci gaba da fiber ƙarfafa thermoplastic abu, da kuma babba sashi ne wani ƙarin guduro abu. Kamar yadda za a iya gani daga adadi, ƙarin kayan aikin resin na iya zama don ƙarfafa ƙarfin fiber. Gully na kayan yana rage haɓakar ɓarna yayin bugawa.

Bugu da kari, MY da YK sun yi amfani da na'urorin da aka samar da su don shirya nau'ikan nau'ikan juzu'i da kuma gwajin injin injin. Sakamakon gwajin ya nuna cewa modules E na samfuran samfuran sun kai 53 Gpa, ma'aunin Poisson γ 0.39, da ƙarfin tensile σb 701 MPa.

Bisa ga lura na MY da YK, sun yi hasashe cewa kasancewar pores na ciki a cikin Layer guda ɗaya na ɓangaren da aka ƙera yana da tasiri sosai a kan kayan aikin injiniya na samfurin, kuma an ɗauka cewa daga baya sun ƙayyade tsarin maganin zafi. bisa ga yanayin kayan don zafi samfurin. Kuma matsawa mai zafi don kawar da porosity na ciki. Sakamakon ya nuna cewa maganin zafin jiki bai inganta ƙarfin ƙarfin samfurin ba (20%), amma samfurin bayan da aka yi zafi ya ninka sau biyu a cikin ma'auni na roba da ƙarfin ƙarfi idan aka kwatanta da samfurin da ba a kula da shi ba. Masu bincike sunyi imanin cewa tsarin matsawa mai zafi yana kawar da pores a cikin monolayer kuma yana haifar da irin wannan karuwa mai yawa a cikin kayan aikin injiniya na samfurin.
