ngā purongo

1. Te kaha o te kume
Ko te kaha kume te taumahatanga nui rawa atu ka taea e te rauemi te tu atu i mua i te totoro. Ko ētahi rauemi kore-pakaru ka huri i mua i te pakaru, engariNgā muka Kevlar® (aramid), he pakarukaru ngā muka waro, me ngā muka karāhe-E, ā, he iti noa te rerekētanga. Ka inehia te kaha kume hei kaha mō ia horahanga waeine (Pa, Pascal rānei).

2. Te ōwehenga o te mātotoru me te kaha ki te taumaha
Ina whakatairitea ngā mātotorutanga o ngā rauemi e toru, ka kitea ngā rerekētanga nui o ngā muka e toru. Mēnā ka hangaia kia toru ngā tauira he rite tonu te rahi me te taumaha, ka kitea wawetia he mama ake ngā muka Kevlar®, ā, kei muri tata mai ngā muka waro, ā,Ngā muka karāhe-ete mea taumaha rawa.

3. Te Tauwehenga o Young
Ko te modulus a Young he ine i te pakari o tētahi rauemi rapa, ā, he huarahi hoki tēnei ki te whakaahua i tētahi rauemi. E tautuhia ana ko te ōwehenga o te ahotea uniaxial (i te kotahi te ahunga) ki te taumahatanga uniaxial (te rerekētanga i te ahunga kotahi). Ko te modulus a Young = te ahotea/taumahatanga, ko te tikanga he pakari ake ngā rauemi he nui te modulus a Young i ērā he iti te modulus a Young.
He rerekē rawa te pakari o te muka waro, te Kevlar®, me te muka karāhe. E rua ngā wā he pakari ake te muka waro i ngā muka aramid, ā, e rima ngā wā he pakari ake i ngā muka karāhe. Ko te ngoikoretanga o te pakari pai o te muka waro he pakarukaru ake. Ina pakaru, kāore e nui te totoro, te rerekētanga rānei.

4. Te mura me te pirau wera
He ātete te Kevlar® me te muka waro ki ngā pāmahana teitei, ā, kāore he pae rewa o tētahi o ēnei. Kua whakamahia ngā rauemi e rua ki ngā kākahu tiaki me ngā papanga ātete ahi. Ka rewa te muka karāhe i te mutunga, engari he tino ātete hoki ki ngā pāmahana teitei. Ko te tikanga, ka taea hoki e ngā muka karāhe hukapapa e whakamahia ana i roto i ngā whare te whakanui ake i te ātete ahi.
Ka whakamahia te muka waro me te Kevlar® hei hanga paraikete tiaki ahi, hei hanga kakahu rānei. He maha ngā wā ka whakamahia ngā karapu Kevlar i roto i te umanga mīti hei tiaki i ō ringaringa ina whakamahi maripi. Nā te mea he onge te whakamahinga o ngā muka anake, he mea nui anō hoki te ātete wera o te matrix (te nuinga he epoxy). Ina werahia, ka tere te ngohengohe o te kapia epoxy.

5. Te Arahi Hiko
Ka arahina te hiko e te muka waro, engari ko Kevlar® memuka karāhekaua. Ka whakamahia a Kevlar® hei kukume i ngā waea i roto i ngā pourewa tuku hiko. Ahakoa kāore e kawe hiko, ka mimiti i te wai, ā, ka kawe hiko te wai. Nō reira, me pania he paninga ātete wai ki a Kevlar i roto i ēnei mahi.

6. Te pirau o te hihi UV
Ngā muka aramidka pirau i te rā me ngā taiao UV teitei. Kāore ngā muka waro, ngā muka karāhe rānei e tino pāngia e te hihi UV. Heoi, ko ētahi o ngā matariki noa pērā i ngā kapia epoxy ka puritia i te rā ka mā, ka ngaro te kaha. He ātete ake ngā kapia polyester me te vinyl ester ki te UV, engari he ngoikore ake i ngā kapia epoxy.

7. Ātete ki te ngenge
Ki te pikohia, ki te whakatikahia tonutia tētahi wāhanga, ka hē i te mutunga nā te ngenge.muka warohe āhua pāngia e te ngenge, ā, ka tino pakaru rawa, engari he ātete ake a Kevlar® ki te ngenge. Kei waenganui i tēnā te muka karāhe.

8. Ātete ki te pakū
He tino ātete a Kevlar® ki te pakū, ā, he uaua ki te tapahi, ā, ko tētahi o ngā whakamahinga noa o Kevlar® he karapu tiaki mō ngā wāhi ka tapahia pea ō ringaringa e te karāhe, e whakamahia ana rānei he mata koi. Kāore i te tino ātete te muka waro me te karāhe.

9. Ātete matū
Ngā muka aramidhe tairongo ki ngā waikawa kaha, ki ngā kawa me ētahi matū whakahāora (hei tauira, te konutai hypochlorite), ka taea ai te whakapōrearea i te muka. Kāore e taea te whakamahi i te wai mākū konutai noa (hei tauira, Clorox®) me te hauwai peroxide me Kevlar®. Ka taea te whakamahi i te wai mākū hāora (hei tauira, te konutai perborate) me te kore e kino ngā muka aramid.

10. Ngā āhuatanga here tinana
Kia pai ai te mahi a ngā muka waro, te Kevlar® me te karāhe, me pupuri tonu ēnei ki roto i te anga (he kapia epoxy te nuinga). Nō reira, he mea nui te kaha o te epoxy ki te hono atu ki ngā momo muka.
Ko te waro me temuka karāheka taea te piri ngāwari ki te epoxy, engari kāore te hononga muka aramid-epoxy i te kaha e hiahiatia ana, ā, nā te iti o te piri ka taea te uru ki te wai. Nō reira, ko te ngāwari o te mimiti wai i ngā muka aramid, me te piri kore e hiahiatia ki te epoxy, ko te tikanga mēnā ka pakaru te mata o te hiato kevlar®, ā, ka uru pea te wai, ka mimiti pea te wai e Kevlar® i ngā muka, ka ngoikore te hiato.

11. Tae me te whatu
He koura mārama te aramid i tōna āhua tūturu, ka taea te tae, ā, he maha ngā tae ataahua e wātea ana. Kei te wātea hoki te muka karāhe i roto i ngā momo tae.muka warohe mangu tonu, ā, ka taea te whakaranu ki te aramid tae, engari kāore e taea te tae i a ia anō.
