Kusarudza pakati pearamid, kabhoni, uye UHMWPE fiber zvakare? Inonzwa senge kumira pamberi pebuffet ine bhajeti rakasimba uye zero nhungamiro.
Kunetsekana kuti "simba rakakwirira" pane dhetabheti ingori kushambadzira, uye imwe isiriyo sarudzo inoreva kuwandisa, kuwandisa, kana kudarika? Hausi wega.
Uku kufananidza kweakakwirira simba aramid, kabhoni, uye UHMWPE faibha inoisa kusimba simba, modulus, kurebesa, density, uye kukanganisa kupikisa patafura imwechete-isina cryptic jargon overload.
Kana iwe wakanamatira kuenzanisa ballistic performance vs. kuoma, kana kupisa kupisa maringe nemutengo, iyo yakadzama parameter matafura muchikamu ichi ndizvo chaizvo izvo zvinotevera dhizaini ongororo inoda.
Kune zvakadzika mabhenji, yambuka - tarisa neindasitiri data senge Teijin aramid technical report:Teijin Aramid Reportuye Toray's carbon fiber dhizaini dhizaini:Toray Carbon Fiber Data.
🔹 Mechanical performance kuenzanisa: tensile simba, modulus, uye elongation maitiro
Aramid, kabhoni, uye UHMWPE fibers ese akaiswa seyepamusoro-kuita yekusimbisa zvinhu, asi iwo mamechanical profiles akasiyana zvakanyanya. Mainjiniya anofanirwa kuenzanisa simba rekusimba, kuomarara, uye kurebesa kutadza pakusarudza iyo fiber chaiyo. Kuenzanisa kunotevera kunotarisa pane zvinogoneka zvivakwa uye zvakajairwa zvikumbiro zvekushandisa mune aerospace, dziviriro, machira emaindasitiri, uye zvigadzirwa zvemitambo.
Nekunzwisisa kuti modulus, kuoma, uye ductility zvinopindirana sei, vagadziri vanogona kuvaka zvakareruka, zvakachengeteka, uye zvakanyanya kusimba zvinoumbwa zvimiro. Ichi chikamu chinopfupikisa musimboti wemakanika misiyano kutungamira sarudzo dzekusarudza zvinhu.
1. Kuenzanisa kusimba kwekusimba kwearamid, kabhoni, uye UHMWPE fibers
Kusimba kwesimba kunotaridza kuti wakawanda sei mutoro unogona kutakura fiber isati yatyoka. UHMWPE nemaaramid fibers anowanzo kusimba musimba chairo (simba - ku- huremu reshiyo) kupfuura yakajairwa kabhoni faibha, zvichiita kuti ive yakanaka kune huremu-inonzwa dhizaini senge ballistic panel, tambo, uye machira epamusoro.
| Fiber Type | Yakajairika Tensile Simba (GPA) | Density (g/cm³) | Chaiyo Simba (GPa / (g/cm³)) | Key Applications |
|---|---|---|---|---|
| Aramid (e.g., Kevlar-type) | 2.8 – 3.6 | 1.44 | ~2.0 – 2.5 | Ballistic nhumbi dzokurwa, tambo, zvipfeko zvekudzivirira |
| Carbon Fiber (yakajairwa modulus) | 3.0 - 5.5 | 1.75 - 1.90 | ~ 1.7 – 2.5 | Aerospace, motokari, zvinhu zvemitambo |
| UHMWPE Fiber | 3.0 - 4.0 | 0.95 - 0.98 | ~ 3.2 – 4.0 | Zvombo zvehondo, tambo, tambo dzekuredza, machira asingadzivirirwe |
2. Modulus uye kuoma maitiro mukugadzirwa kwemaitiro
Carbon fiber inomira kunze kune yayo yakanyanya kukwirisa elastic modulus, ichipa kuomarara kwepamusoro pahuremu hwakaderera.
