Yize inqubo ye-classical fused deposition molding (FDM) inezinzuzo ezingokwemvelo ekwakhiweni kwezingxenye eziyinkimbinkimbi zokwakheka, izingxenye ezenziwa kusetshenziswa lobu buchwepheshe zisenezinkinga zamandla anganele nokumelana nokushisa okuphansi.

Ukukhulisa amandla womkhiqizo, ukusetshenziswa kwezinto ezingasindi, ezinamandla amakhulu okuqinisa izinto kuyindlela ephumelela kakhulu. Abanye abacwaningi bahlanganise imicu eqoshiwe ezintweni ezenziwe ngotshani nezintambo eziqiniswe i-fiber ze-FDM. Yize inqubo ejwayelekile ye-FDM ezuzwe njengefa kwezintambo eziqinisiwe ze-fiber inenzuzo yokwakha izingxenye eziyinkimbinkimbi ze-geomorphic, ukuqiniswa kwayo kwamandla omkhiqizo akubonakali kakhulu, futhi ayikwazi ukuhlangabezana nezidingo zamandla aphezulu ebesizilindele . Uma kuqhathaniswa nezinto eziqoshiwe zensimbi eqinisiwe, izinto eziqinisiwe zefayibha zingakhuphula kakhulu amandla omkhiqizo, kepha ngenxa yemikhawulo eqhubekayo yefayibha, indlela yokubumba inokuntuleka kwamandla okwenza izingxenye eziyinkimbinkimbi zokwakha.

Ukuze kuxazululwe le nkinga eshiwo ngenhla yokubumba okuqinisiwe kwefayibha, abaphenyi BAMI kanye no-YK abavela esikoleni esiphakeme saseJapan abakhethekile ekwakhiweni nasekwakhiweni kohlobo olusha lombhobho wesikhumba se-extrusion (Umfanekiso 1).

Ngokungafani nemishini ejwayelekile yokuqinisa i-fiber, umbhobho usebenzisa amadivayisi okuphakelayo amabili ukulawula okuphakelayo kocingo oluqhubekayo lwe-carbon fiber oluqiniswe ngocingo lwe-thermoplastic kanye nocingo olwengeziwe lwe-resin. I-fiber eqhubekayo iqinisa i-thermoplastic wire esetshenziswa yibo ngocingo olwenziwe nge-PA6 esongwe i-carbon fiber enobubanzi obungu-0.3 mm, lapho okuqukethwe yivolumu ye-carbon fiber Vf ilawulwa ku-50%, futhi into eyengeziwe ye-resin yinayiloni 645. Eyodwa Isigaba esinqamulelayo sabadlali esiphrintwe ngumbhobho sikhonjiswa ku-Fig. 2. Ingxenye engezansi yesendlalelo esisodwa iyintambo eqhubekayo ye-fiber eqinisiwe ye-thermoplastic, kanti ingxenye ephezulu ingumbhalo we-resin owengeziwe. Njengoba kungabonakala kulesi sibalo, okokusebenza okwengeziwe kwe-resin kungenza ukuqiniswa kwe-fiber. I-gully yempahla inciphisa ukwenziwa kwama-voids ngesikhathi sokuphrinta.

Ngaphezu kwalokho, i-MY ne-YK basebenzise imishini eyenziwe yibo ukulungiselela ama-specimens wokuqina futhi benziwa izivivinyo zokuqina kokuqina. Imiphumela yokuhlolwa ikhombise ukuthi i-elastic modulus E yamasampuli ifinyelele kuma-53 Gpa, isilinganiso sikaPoisson γ 0.39, namandla aqine σb 701 MPa.

Ngokusho kokubukwa kwe-MY ne-YK, bacabanga ukuthi ukutholakala kwama-pores angaphakathi kusendlalelo esisodwa sengxenye ebunjiwe kube nomthelela omkhulu kuzakhiwo zomkhiqizo zomkhiqizo, futhi bekucatshangwa ukuthi ngemuva kwalokho banqume inqubo yokwelashwa kokushisa ngokusho kohlobo lwendaba ukushisa isampula. Nokucindezela okushisayo ukuqeda i-porosity yangaphakathi. Imiphumela ikhombise ukuthi ukwelashwa kokushisa akuzange kuthuthukise kakhulu amandla we-tensile wesampula (20%), kepha isampula ngemuva kokucindezela okushisayo liphindwe kabili ngemodulus nokunwebeka kwamandla okuqina uma kuqhathaniswa nesampula engalashwa. Abaphenyi bakholelwa ukuthi inqubo yokucindezela eshisayo iqeda ama-pores ku-monolayer futhi iholela ekukhuleni okukhulu kwezakhiwo zomkhiqizo.

Izithenjwa:Yamawaki, M., &Kouno, Y. (2018). Ukwenziwa kanye nokusetshenziswa kwezinhlamvu zemishini ye-thermoplastic ye-carbon fibre-reinforced thermoplastic kusetshenziswa i-preform ngokuphrinta okunezinhlangothi ezintathu nangokubumba kokucindezela okushisayo. Izinto Ezithuthukisiwe Ezihlanganisiwe, 27(2), 209-219. doi: 10.1080/09243046.2017.1368840

Xhumanisa nale ndatshana: Ukucindezela okushisayo ngemuva kokulashwa kwe-3D ukuphrinta okuqhubekayo kwe-carbon fiber kuqiniswe i-thermoplastic

Isitatimende Esiphrintiwe: Uma ingekho imiyalo ekhethekile, zonke izindatshana ezikulesi sayithi zingokoqobo. Sicela ukhombise umthombo wokuphrinta kabusha: https: //www.cncmachiningptj.com/ ezinthanks！
