Badminton thawj zaug tshwm sim ua kis las ua si ntawm 1972 Munich Olympics; Xyoo 1988, nws rov tshwm sim ua kev ua kis las ntawm Seoul Olympics; Los ntawm xyoo 1992 Barcelona Olympics, ntaus pob tesniv tau dhau los ua qhov kev tshwm sim Olympic, nrog thawj tus txiv neej thiab poj niam cov kev sib tw thiab ob leeg sib tw. Qhov sib xyaw ua ke tau ntxiv rau ntawm 1996 Atlanta Olympics. Wheelchair badminton ua nws debut ntawm 2021 Tokyo Olympics.
Kev Txhim Kho Keeb Kwm ntawm Carbon Fiber Composite Materials hauv Badminton
Cov rackets thaum ntxov tshaj plaws yog ua los ntawm cov khoom ntoo, thiab ua raws li cov txheej txheem kev tsim kho ntawm cov rackets, lawv tau hloov mus rau cov ntaub ntawv ntoo laminated. Pib txij li xyoo 1960, cov rackets ntaus pob ncaws pob pib siv cov txhuas lossis hlau, nrog cov txhuas feem ntau siv rau lub taub hau thiab cov hlau rau cov ncej.
Vim tias muaj kev ntxhov siab ntau dhau ntawm kev sib koom ua ke ntawm lub taub hau thiab lub taub hau thaum ua si, thaj chaw no tau ua rau tawg. Xyoo 1968, Yonex tau qhia txog T-kev sib koom lub tswv yim, txuas lub taub hau mus rau ncej los ntawm kev ntxig peb lub ntsiab zoo li tus T, ua los ntawm cov hlau muaj zog. Xyoo 1978, Yonex tau tsim thawj cov pa roj carbon fiber ntau ntaus pob ntaus pob hauv Nyij Pooj: Carbonex 8 B-8500B1, hnyav dua 100 grams (Daim duab 1). Txij thaum ntawd los, feem ntau kev sib tw badminton rackets tau siv cov ntaub ntawv carbon fiber ntau, thaum pheej yig dua kev ua si rackets tseem siv txhuas thiab hlau.

Cov txheej txheem tsim khoom ntawm carbon fiber composite (CFRP) badminton rackets zoo ib yam li cov ntaus pob tesniv tab sis kuj muaj qhov sib txawv tseem ceeb. Cov ncej yog hollow, ua nyob rau hauv ib txoj kev zoo sib xws rau lub moj khaum ntawm ib tug ntaus pob tesniv racket, tab sis nws yog ncaj nrog ib tug ntau me me cross-section (lub voj voog); lub taub hau tsis yog hollow tab sis khoom, raws li nws yog tsim los ntawm folded thiab compressed carbon fiber pre-preg, uas yog ces them nyob rau hauv ib tug pwm; Tom qab ntawd, lub taub hau thiab lub taub hau (pre-kho) ncej txuas nrog CFRP T-joint, zawv zawg ob lub tswv yim kab rov tav mus rau qhov kawg ntawm lub folded pre-preg thiab ntsug ntsug rau hauv lub hollow ncej, uas yog ces kho nyob rau hauv lub pwm.
Cov Kev Txhim Kho Kawg Nkaus Hauv Kev Ntaus Ntaus Nrig Siv Cov Khoom Siv Carbon Fiber Composite
Badminton rackets yog txawv los ntawm ntau yam yam ntxwv: yooj, qhov hnyav, thiab qhov sib npaug ntawm qhov taw tes, xws li lub taub hau-hnyav mus rau lub taub hau-lub teeb. Cov ntaub ntawv carbon fiber ntau tuaj yeem txhim kho cov yam ntxwv no los ntawm kev hloov hom fibers siv (los ntawm lub zog siab mus rau ultra-high modulus carbon fiber), kev taw qhia fiber ntau, thiab txheej txheej. Kev hloov kho pwm tuaj yeem ua kom zoo dua lub taub hau hla ntu los txhim kho kev tiv thaiv kom siab nruj thiab txo qis aerodynamic luag. Cov tuam txhab nto moo tshaj plaws yog Yonex, Victor, Carlton, FZ Forza, Dunlop, Li Ning.
Kev ua tau zoo ntawm kev ntaus pob tesniv tuaj yeem ua kom zoo dua los ntawm kev sib xyaw ntau hom khoom siv fiber ntau (Daim duab 2), xws li Yonex's "Nanoflare 800 Pro," uas muaj cov tawv tawv Toray M40X carbon fiber thiab ultra-high molecular hnyav polyethylene fibers (kom txhim kho shock absorption). Yonex Carbonex8000 lub taub hau siv cov khoom sib xyaw ntawm cov khoom siv fiber ntau nrog titanium mesh lossis carbon nanotubes kom ua tiav qhov kev sib tw ruaj khov.

Tsis tas li ntawd, CFRP yog siv nyob rau hauv kev ntaus pob tesniv tshaj lub racket, xws li nyob rau hauv lub tuam txhab Victor lub CarbonSonic shuttlecock, uas siv cov ntaub npuag ntxiv nrog CFRP (Daim duab 3) kom txo qhov hnyav thiab txhim khu kev ruaj ntseg.

Txij li thaum qhov tshwm sim ntawm kev ntaus pob tesniv ntawm 2021 Tokyo Paralympics, ob lub rooj zaum muaj log (Daim duab 4) thiab cov neeg ncaws pob sawv (Daim duab 5) tau siv cov pa roj carbon fiber ntau hauv kev sib tw. Tshwj xeeb tshaj yog rau cov neeg ncaws pob hauv lub rooj zaum, lub rooj zaum lub rooj zaum yog qhov nyuaj, nrog welded aluminium lossis magnesium raj siv rau cov qauv ntawm lub log, tab sis lub log thiab lub rooj zaum qee zaum siv cov khoom siv carbon fiber ntau los txo qhov hnyav thiab yog li txhim kho kev txav mus los.
