Ngokumalunga neBhodi ye-FRP engatshiyo

I-FRP (i-Glass Fiber Reinforced Plastic) iibhodi ezingenamlilo ziye zaba yimfuneko kulwakhiwo lwangoku ngenxa yokumelana nomlilo okugqwesileyo kunye nezakhiwo. Isicelo sabo silandela imigangatho engqongqo yamazwe ngamazwe kunye neyengingqi ukuqinisekisa ukuthembeka kwiimeko ezahlukeneyo zokwakha.

Ehlabathini lonke, iiphaneli ze-FRP ezingenamlilo kufuneka zihlangabezane nemigangatho engqongqo yokuqinisekisa ukhuseleko lomlilo kunye nomgangatho. I-International Organisation for Standardization (ISO) ibeke iimpawu eziphambili, ezifana ne-ISO 5660-1, esetyenziselwa ukuvavanywa kokusasazeka komlilo. Lo mgangatho ulinganisa iiparamitha ezifana nezinga lokukhululwa kobushushu kunye nokuveliswa komsi. Lo mgangatho uqinisekisa ukuba iipaneli zihlangabezana nemigangatho yokhuseleko lomlilo kwimarike yehlabathi.
EYurophu, isakhelo se-EN (i-European Norms) sinegunya. I-EN 13501-1 ihlela ukusebenza komlilo kweemveliso zokwakha, kwaye iiphaneli ze-FRP ezingatshiyo zifuna ukufikelela ubuncinci kwi-B{8}}s1, d0 okanye inqanaba eliphezulu. Olu lwahlulo lumele indawo yokutshisa ephantsi (B), umsi ophantsi kakhulu (s1), kwaye akukho kuvuza kwedangatye (d0) - okubaluleke kakhulu kuluntu kunye nezakhiwo zorhwebo. UMntla Melika ulandela imigangatho yoMbutho waseMelika woVavanyo kunye neZixhobo (ASTM). I-ASTM E84, ekwabizwa ngokuba yi "Steyner Tunnel Test", isetyenziselwa ukuvavanya ukusasazeka kwedangatye kunye nesalathiso sokuvelisa umsi. Iiphaneli ze-FRP ezingatshiyo zokuhlobisa kwangaphakathi zidla ngokufuna ukuhlangabezana nomgangatho wesalathiso sokusasazeka kwedangatye elingaphantsi kwe-25 (A grade) (ukuthobela iikhowudi zokwakha kwindawo{18}}zomngcipheko ophezulu njengeepaseji kunye nezinyuko). E-China, umgangatho osebenzayo ngumgangatho wesizwe (GB), njengomgangatho we-GB 8624-2012 malunga nokuhlelwa kokusebenza kokutsha kwezinto zokwakha. Apha, iipaneli ze-FRP ezingenamlilo zifuneka ukuba zihlangabezane nemigangatho ye-A (engenakutsha) okanye i-B1 (enzima ukutshisa) ngokweemfuno zemeko yesicelo. Kukho neminye imigangatho efana ne-GB/T 25722 echaza iipropati zoomatshini, kubandakanywa amandla okugoba kaMkhulu kuno okanye alingana ne-80 MPa kunye namandla empembelelo ye-Greater than or kulingana ne-20 kJ/m², ukuqinisekisa ukuthembeka kwesakhiwo kwiimeko zomlilo.
