Hoʻohālikelike hana o ka paipu pulupulu kalapona a me ka paipu pulu aniani
ʻO ka paipu pulupulu kalapona a me ka paipu pulu aniani ʻelua mau ʻano noi o nā paipu hui.Hana ʻia ka paipu pulupulu kalapona ma ka wili ʻana, pultrusion a i ʻole ka wili ʻana o ke kalapona fiber prepreg, ʻoiai ua huki ʻia a hoʻokuʻu ʻia e ke aniani fiber a me ka resin.Hoʻohana nui ʻia nā paipu o kēia mau mea ʻelua i ka aerospace, ka hana kaʻa, nā haʻuki a me nā ʻoihana ʻē aʻe.He aha nā ʻokoʻa o kā lākou hana?
ʻO ka nui o ka paipu carbon fiber he 1.6g / cm ³, ʻoi aku ka liʻiliʻi ma mua o ka alumini alumini, ʻo ka ikaika tensile o ka paipu kila he 300 ~ 600MPa, ʻo ka ikaika tensile o ka paipu alumini alumini he 110 ~ 136MPa, a me ka ikaika tensile o ʻO ka paipu kalapona he 1500MPa.ʻO ka helu hoʻonui wela o ka carbon fiber composite he-1.4 × 10 ^ -6, hiki ke hōʻoia i ka paʻa o ka nui o ka huahana a ʻaʻole maʻalahi ke deform.ʻO ka palena ikaika o ka luhi o ka carbon fiber tube he 70% ~ 80% o kona ikaika tensile.I ka hana ana ma lalo o ka manawa lōʻihi alternating haawe, ka carbon fiber paipu i oi paʻa a me ka lōʻihi lawelawe ola.A he maikaʻi ka conductivity uila a me ka hana pale electromagnetic maikaʻi.
ʻOi aku ka nui o ke kaumaha o ke aniani fiber tube 2.53 ~ 2.55g/cm ³ ma mua o ka paipu carbon fiber o ka kikoʻī like, tensile ikaika 100 ~ 300MPa, modulus o ka elasticity 7000MPa, elongation ma ka haʻihaʻi 1.554%, Poisson's ratio 0.22, coefficient of thermal expansion. 4.8×10 ^-4.ʻO ke koʻikoʻi he nui nō hoʻi, a hiki i ka 1% ~ 2%, e haki ka resin, no laila, ʻaʻole i ʻoi aku ke koʻikoʻi o ke aniani fiber tube ma mua o 60% o ke koʻikoʻi palena, ʻoiai ʻo ka pahu kalapona he modulus elastic nui a hiki ke mālama i nā waiwai mechanical maikaʻi ma lalo o ke kūlana koʻikoʻi palena.
No ka hōʻuluʻulu ʻana, ʻoi aku ka maikaʻi o ka paipu pulupulu kalapona ma mua o ke aniani pulu i loko o nā waiwai mechanical, akā ʻo kēlā me kēia o lākou i kona kahua noi ponoʻī, no ka laʻana, pono ke aniani pulupulu i ke kahua kahi e pono ai ka insulation.
