Ukusetshenziswa Kwezinto ze-CF / PEEK Emkhakheni Wezokwelapha

Kuyini i-CF / PEEK?

Izinto ezihlanganisiwe eziqhubekayo ze-CF / PEEK zibhekisa ku-carbon fiber CF eqhubekayo njengokuqiniswa ne-PEEK, eyokuqala yamaplastiki akhethekile obunjiniyela, njenge-matrix. Lezi zimbili zakhiwa ukushisa okuphezulu kanye nenqubo yokubumba ingcindezi ephezulu, futhi impahla ye-resin igxiliswa ku-carbon fiber. Lezi zombili zihlangene ngokomzimba. Impahla ehlanganisiwe.

Ukusebenza kwe-CF / PEEK

Uma kuqhathaniswa nezinhlanganisela ezijwayelekile ze-CF eziqinisiwe ze-epoxy-based, i-PEEK inebanga elibanzi lokusebenzisa imitholampilo nokusebenza okungcono. I-epoxy resin iyi-matrix ejwayelekile ye-thermosetting resin. Uma kuqhathaniswa ne-PEEK, i-epoxy resin inezici zokuqaqamba okukhulu nokumelana nokushisa okuphansi. Ngesikhathi esifanayo, i-epoxy resin inokumelana okuncane kwe-hydrolysis. Ukunwebeka kuphakathi kuka-5-7%, futhi ubude be-PEEK resin bungafinyelela ngaphezu kuka-20%. Ubulukhuni obuphakeme bezinto ze-PEEK zenzelwe ukukhubazeka kwe-epoxy resin. Ubulukhuni buhle, okokusebenza kuhloselwe ukumelana nokukhathala okuhle, ukubopha okuhle kwe-interlayer futhi akulula ukuqhekeka. Ngakho-ke, izinto ezihlanganisiwe ze-CF eziqinisiwe ze-epoxy resin zisetshenziswa kakhulu kumatafula wokusebenza wezokwelapha, amafreyimu ahleliwe, umbhede nezinye izinto, futhi azikulungele ukuhlinzekelwa ukwenziwa kwamathuluzi okuhlinza amathambo.

I-PEEK resin matrix material emsulwa inokumelana namazinga okushisa esikhathi eside ngenhla kwama-260 ° C. Izinto ezihlanganisiwe zeCF / PEEK eziqhubekayo zithuthukisa kakhulu ukumelana nokushisa Imishini ye-PEEK izinto zokwakha. Ucwaningo oluhlobene lukhombisa ukuthi izinga lokushisa lokumelana nokushisa kwezinto ezihlanganayo ze-CF / PEEK lisondele endaweni yokuncibilika ye-PEEK, eyi-334. izinga lokushisa kanye nengcindezi ephezulu yokushisa inzalo.

Uma kuqhathaniswa ne-aluminium alloy yendabuko kanye nensimbi engagqwali, ubukhulu be-aluminium alloy bungu-2.8g / cm3, ubukhulu bensimbi engagqwali ngu-7.3g / cm3, futhi ubukhulu bezinto ezihlanganayo ze-CF / PEEK ngu-1.5-1.6g / cm3. Inesisindo esincane kepha inamandla amakhulu. Imiphumela yokuhlolwa ikhombisa ukuthi ezinye izakhiwo ze-CF-PEEK zidlule insimbi engagqwali. Ngasikhathi sinye, i-PEEK egcizelela i-carbon fiber eqhubekayo inokudluliswa okuhle kwe-X-ray, okwenza ukuhlinzwa komtholampilo kube enembile futhi kuphephe kakhulu. Izinto eziqiniswe nge-carbon fiber azinawo umuzwa obandayo wensimbi lapho uthinta, okwenza udokotela azizwe ekhululekile ngesikhathi sokuhlinzwa.

Uma kuqhathaniswa nempahla yendabuko ye-carbon fiber powder eguquliwe ye-PEEKCF30, amandla aphezulu we-CF-PEEK nezimpawu zemodeli ephezulu kunika izinto ezihlanganisiwe amandla aphezulu, ama-modulus nezimpawu zokulwa nokukhubazeka. Amandla womshini andiswa okungenani ama-3 times, futhi i-modulus nayo inyuswe okungenani ama-3 times. It has ukuzinza ntathu kangcono nokumelana ukusonteka.
