Ukuqhathaniswa kokusebenza kwe-carbon fibre tube ne-glass fibre tube

I-Carbon fibre tube kanye ne-glass fibre pipe yizinhlobo ezimbili zokusetshenziswa zamashubhu ayinhlanganisela.I-carbon fiber tube yenziwa ngokusonteka, i-pultrusion noma ukugoqa kwe-carbon fibre prepreg, kuyilapho ithubhu ye-fiber yengilazi idwetshwa futhi ikhishwe nge-glass fibre kanye ne-resin.Amapayipi alezi zinto ezimbili asetshenziswa kabanzi ku-aerospace, ukukhiqiza izimoto, ezemidlalo nezinye izimboni.Uyini umehluko ekusebenzeni kwabo?

Ukuminyana kweshubhu le-carbon fibre ngu-1.6g/cm ³, okungaphansi kwalokho kwe-aluminium alloy, amandla aqinile wepayipi lensimbi ngu-300 ~ 600MPa, amandla aqinile wepayipi le-aluminium alloy ngu-110 ~ 136MPa, futhi amandla aqinile we- I-carbon fiber tube imayelana ne-1500MPa.I-coefficient yokwandisa okushisayo ye-carbon fiber composite ngu-1.4×10 ^-6, engaqinisekisa ukuthi usayizi womkhiqizo uzinzile futhi akulula ukuwohloka.Umkhawulo wamandla wokukhathala we-carbon fiber tube ungama-70% ~ 80% wamandla ayo aqinile.Uma usebenza ngaphansi komthwalo oshintshanayo wesikhathi eside, ishubhu le-carbon fiber lizinza kakhulu futhi linempilo ende yesevisi.Futhi impahla ye-carbon fiber inokuhamba kahle kukagesi nokusebenza okuhle kakhulu kokuvikela i-electromagnetic.

Ukuminyana kweshubhu ye-glass fibre engu-2.53~2.55g/cm ³isinda kunaleyo yeshubhu ye-carbon fibre yesimo esifanayo, amandla aqinile 100 ~ 300MPa, i-modulus of elasticity 7000MPa, ubude ngesikhathi sekhefu 1.554%, isilinganiso sika-Poisson esingu-0.22, ukunwetshwa okushisayo kwe-thermal 4.8×10 ^-4.I-strain nayo inkulu ngokuqhathaniswa, futhi lapho uhlobo lufinyelela ku-1% ~ 2%, i-resin izophuka, ngakho-ke ukucindezelwa okuvumelekile kwe-glass fiber tube akudluli u-60% wengcindezi yomkhawulo, kuyilapho ishubhu le-carbon fiber line- i-elastic modulus enkulu futhi ingagcina izakhiwo ezinhle zemishini ngaphansi kwesimo sokucindezeleka esilinganiselwe.

Ukufingqa, i-carbon fibre tube inezinzuzo eziningi kune-glass fibre tube ezindaweni ezisebenza ngomshini, kodwa ngayinye yazo inenkambu yayo yesicelo, isibonelo, ithubhu ye-glass fibre iyadingeka endaweni yesehlakalo lapho ukufakwa kuyadingeka khona.
