Kev tshawb fawb txog kev cuam tshuam cov khoom ntawm basalt fiber ntau pob zeb
Cov vaj tse pob zeb yuav ntsib teeb meem tshwm sim thaum siv, uas tuaj yeem ua rau muaj kev puas tsuaj hauv cheeb tsam rau cov qauv, lossis qhov tshwm sim loj xws li kev tawg ntawm cov qauv, ua rau kev poob tsis tuaj yeem. Txhawm rau kom muaj kev nyab xeeb ntawm cov pob zeb hauv qhov cuam tshuam, nws yog ib qho tseem ceeb uas yuav tsum tau kawm txog qhov cuam tshuam ntawm pob zeb. Qhov cuam tshuam cov khoom ntawm Basalt Fiber ntau pob zeb tau kawm los ntawm SHPB xeem los yog poob rauj cuam tshuam kuaj.
Los ntawm kev ntsuam xyuas qhov cuam tshuam pom tau tias kev sib xyaw ntawm basalt fibers tuaj yeem txhim kho qhov cuam tshuam toughness ntawm pob zeb, cuam tshuam toughness nrog qhov nce ntawm cov nyiaj. basalt fibers pom qhov sib txawv ntawm kev nce thiab tom qab ntawd txo qis, cov kev tshawb fawb ntsig txog qhia tau hais tias qhov ntim ntawm basalt fiber sib xyaw 0.3% thiab 0.36% ntawm basalt fiber ntau qhov kev ua tau zoo yog qhov zoo tshaj plaws; piv rau cov yam ntxwv kev puas tsuaj ntawm cov qauv, kev txhim kho ntawm cov kab nrib pleb thiab qhov kawg kev puas tsuaj rau daim ntawv ntawm pob txha, pom tias basalt fiber ntau pob zeb rau cov yas puas, piv txwv li, kev sib xyaw ntawm basalt fiber ntau tuaj yeem ua rau cov pob zeb ua tau zoo nqus cov cuam tshuam lub zog thiab muaj cov nyhuv toughening ntawm cov pob zeb. Kev sib piv ntawm cov yam ntxwv kev puas tsuaj ntawm cov ntawv xeem, kev txhim kho tawg thiab daim ntawv kawg ntawm kev puas tsuaj tawg, pom tias cov pob zeb basalt fiber ntau rau cov yas puas, uas yog, sib xyaw nrog basalt fibers tuaj yeem ua kom cov pob zeb zoo nqus tau qhov cuam tshuam lub zog, thiab muaj cov nyhuv toughening ntawm cov pob zeb. Cov kws tshawb fawb tau kawm txog qhov cuam tshuam ntawm basalt fiber ntau nrog qhov ntim ntawm basalt fiber (0%, 0.4%, 0.6%, 0.8%) thiab qhov ntev ntawm basalt fiber (6mm thiab 18mm) raws li qhov sib txawv. Nws tau pom tias basalt fibers tuaj yeem txhim kho qhov cuam tshuam toughness ntawm pob zeb, thiab qhov cuam tshuam toughness nrog kev nce ntawm fiber ntau sib xyaw thiab ua kom loj dua; tib qhov sib xyaw fiber ntau, fiber ntau ntev ntawm 6 hli cuam tshuam kev ua haujlwm zoo dua li qhov ntev ntawm 18mm fiber ntau pob zeb.
Hauv cov ntsiab lus, basalt fiber ntau admixture tuaj yeem txhim kho qhov cuam tshuam kev ua tau zoo ntawm cov pob zeb, tab sis qhov zoo tshaj plaws fiber ntau admixture tsis zoo ib yam, los ntawm kev sib piv kev soj ntsuam pom tias qhov tshwm sim no tshwm sim los ntawm txoj kev sim, kev sib xyaw ua ke, basalt fiber ntau admixture thiab lwm yam, kev sib koom ua ke ntawm cov ntsiab lus tseem ceeb yuav tsum tau ntxiv dag zog rau qhov kev xeem yav tom ntej. Tsis tas li ntawd, cov kev tshawb fawb uas twb muaj lawm tsom rau cov nyhuv ntawm fiber ntau npaum li cas ntawm nws cov kev cuam tshuam kev ua tau zoo, thiab yuav tsum tau ua nyob rau yav tom ntej los kawm txog cov txiaj ntsig ntawm cov kab mob thiab lwm yam cuam tshuam rau kev ua haujlwm.
