Ko te nuinga o ngā āhua mātai karbon kevlar e whai ana i ngā ōwehenga mai i te 50/50 ki te 70/30 karbon ki te kevlar mā te taimaha, ā, ko te 60/40 he kōwhiringa noa pono. Ko te ōwehenga tika e hāngai ana ki ngā herekorenga motuhake o te whakamahinga, me te nui ake te karbon e hoatu ai te pūmahara me te kaha, inā ko te nui ake te kevlar e pai ake ai te uaua ki te patunga me te pūmahara. Ka taea te hanga ōwehenga ritenga hei ū ki ngā herekorenga mahi motuhake, ahakoa ko ngā ōwehenga noa e tuku ana i te utu me te wātea pai.
Pēhea e pā ai te tauwāhi upenuku ki te mahi o te āhua karbon kevlar
Ko te tau o te raranga e whai pānga nui ana ki ngā īngoa mekameka me ngā āhuatanga hangarua o te mātā o te kāpara karbona kevlar. Ko te raranga tuarā e tuku ana i te pūmahara tinowari me ngā īngoa paratata engari he uaua ake pea te whakapaipai ki runga i ngā mata takotoranga. Ko te raranga twill e tuku ana i te āhua pai ake me te iti ake te crimp, e āwhina ana kia māmā ake te whakamahi i te wā o te layup, i te noho tonu i ngā īngoa mekameka pai. Ko te raranga satin e tuku ana i te ahunga pai rawa atu me te āhua pai ake engari he iti ake pea te tinowari mōhio ki ngā raranga tuarā.
He aha ngā wāhi hōuhu e tūtohu ana mō te mātā karbona kevlar
Ko ngā wāhi tukatuka mō te matapihi kihini kevlar e noho ana i waenganui i te 120°C ki te 180°C, e hāngai ana ki te pūnaha harore me ngā here o te whakamahi. Ko ngā wāhi iti ake, pērā i te 120-140°C, e mahi pai ana mō ngā pūnaha epoxy ka iti ake te totohu māmā i waenganui i ngā aho kihini me ngā aho kevlar. Ka taea te whakamahi i ngā wāhi teitei ake, āpiti atu ki te 180°C, mō ngā whakamahinga tikangia e hiahiatia ana ngā īngoa rite tino, ahakoa me tino mātara ki te hoahoa o te wāhi tukatuka kia kaua ai te sunehetanga o ngā aho kevlar, i te nuinga rānei o te totohu a-roto.
Ka taea te whakatika i te matapihi kihini kevlar mēnā ka marerea i te wā o te hanganga?
Ko ngā maimoatanga iti ki te matapihi kihini kevlar i te wā o te whakamahinga e taea ana te whakaora mā te whakamahi i ngā tikanga e hāngai ana, ahakoa ko te tikanga whakaora e hāngai ana ki te rahi me te momo maimoatanga. Ka taea te whakatika i ngā tarau iti, āwhina rānei i ngā aho pakaru mā te whakauru i ngā taputapu e hāngai ana me ngā pūnaha paraihe. Heoi anō, e herea ana te maimoatanga nui ki te whakakapi i te wāhanga matapihi kua pirangi kia mau ai te kaha o te hanganga. Ko te aukati mā ngā tikanga whakamahinga tika, me ngā tikanga rokiroki anō hoki hei ara hauora kia mau ai te kounga o te matapihi kihini kevlar i roto i ngā prosihia whanaketanga.
