Carbon fiber ine hunhu hwekusimba kwepamusoro uye huremu huremu, uye iyo inoumbwa zvinhu ine polymer yakanyatsokodzera aerospace, indasitiri yemotokari, mablades emhepo turbine uye zvinhu zvemitambo.Nekudaro, zvinhu zvakaumbwa zvakadaro zvichakundikana zvine njodzi pasina yambiro, zvakafanana nekudonha kweceramics.

Munguva pfupi yapfuura, vaongorori kubva kuOak Ridge National Laboratory neVirginia Tech uye State University vakagadzira hunyanzvi uye vakaiburitsa muChinyorwa cheComposites Sayenzi neTekinoroji.Nekungowedzera nano-TiO2, inogona kupa yambiro yekutanga yekurasikirwa nekuita.

Carbon fiber composite zvinhu, kunyanya zvinoumbwa zvinhu zvakavakirwa pa epoxy resin, zvinowanzoitika kune delamination kana chisungo chiri pakati pefiber uye matrix chikatadza.Mukushaikwa kwezviratidzo zvekunze zveyambiro, kutsemuka kwakamwe kamwe kunogona kuitika, izvo zvinoganhurira kubatsira kwezvinhu izvi zvakaumbwa mumashandisirwo ezvimiro.Vanhu vari kutsvaga nzira dzakasiyana dzekutarisa kurongeka kwekabhoni fiber composites, sekumisikidza piezoresistive zvinhu muzvinyorwa, izvo zvinoshandura kuramba nekuomerwa.Piezoresistive zvinhu zvinogona kushandura mechanical strain kuita masaini emagetsi, ayo anogona kuwonekwa nema sensors kuti atarise hutano hwehutano hwezvinhu zvinosanganiswa.

Vatsvakurudzi vakaisa TiO2Nano titanium dioxidenanoparticles mupolymer coating kana saizi yekabhoni fiber kuita kuti piezoresistive zvinhu zvigovane zvakafanana mukati memusanganiswa zvinhu.Sizing inowanzo shandiswa ku carbonized carbon fiber, kuitira kuti zvive nyore kugadzirisa uye kushandisa uye kusanganisa pamwe nematrix, uye pakupedzisira kugadza kukwanisa kunzwa kunetseka mukuita uku.Kana kudzvinyirirwa kuchibviswa, kushorwa kuri zero, uye kana kumanikidzwa kuchigadzirwa, kushorwa kunowedzera.Ehe, huwandu hweTiO2 nanoparticles hwakawedzerwa hunoda kudzorwa, yakawandisa chikamu chinoderedza kusimba kweiyo inoumbwa zvinhu, uye kuwedzera kwakakodzera kunosimudzira iyo damping performance (shock absorption uye buffering performance) yezvinhu.

Hongwu kambani inopa Nano titanium dioxide sezvinotevera:

1. Anatase TiO2, saizi 10nm, 30-50nm.99%+

2. Rutile TIO2, saizi 10nm, 30-50nm, 100-200nm.99%+

Ndapota inzwa wakasununguka kutibata nesu kune chero mibvunzo.
