Cov ntaub ntawv ntse uas tuaj yeem saib xyuas lawv cov qauv kev ncaj ncees hauv lub sijhawm tiag tiag thiab kho kev puas tsuaj yuav txuas ntxiv lub neej ntawm cov khoom siv hauv kev thauj mus los thiab kev siv hluav taws xob txuas ntxiv. Tam sim no, cov kws tshawb fawb los ntawm Queen Mary University of London, Lough-borough University, Warwick University thiab Imperial College London tau coj txoj hauv kev ib txwm muaj thiab tsim cov khoom siv kho tus kheej thiab kho tus kheej.
Cov kws tshawb fawb tau pom 'tshiab' muaj peev xwm ntxiv rau kev kho dua tshiab thiab kev saib xyuas kev noj qab haus huv los ntawm cov txheej txheem yooj yim ntawm interlacing composite laminates. Thaum ua kom lub zog ntawm lub laminate, nws kuj muaj kev ua haujlwm ntawm kev kho yooj yim, uas daws cov teeb meem ntawm kev ua haujlwm tsis zoo ntawm cov khoom siv sib xyaw tam sim no thiab tsis muaj peev xwm ua kom pom thiab kho kev puas tsuaj sab hauv, thiab txuas ntxiv cov kev pabcuam. lub neej ntawm cov khoom sib xyaw.
Cov tswv yim kho tus kheej rau cov ntaub ntawv feem ntau vam khom cov txheej txheem extrinsic siv cov tshuaj kho los yog cov txheej txheem hauv nruab nrab raws li cov ntaub ntawv rov qab los yog kev sib cuam tshuam supra-molecular. Txawm li cas los xij, qhov sib ntxiv ntawm cov kua lossis cov khoom siv kho kom zoo rau cov txheej txheem sib xyaw tuaj yeem cuam tshuam rau lawv cov khoom siv thauj khoom thiab ua rau muaj kev nyuaj ntawm cov txheej txheem tsim khoom. Hloov chaw, cov kws tshawb fawb staggered nyias txheej ntawm thermoplastic ntawm cov pa roj carbon fiber ntau txheej. Txhawm rau kho qhov kev puas tsuaj, cua sov thiab siab yuav tsum tau thov kom cov thermoplastic diffuses rau hauv qhov chaw puas thiab ua rau tawg. Thermoplastic txheej muab ob qho tib si lub peev xwm los kho tus kheej yam tsis muaj kev cuam tshuam cov khoom siv kho tshuab.
Tsis tas li ntawd, cov neeg siv tuaj yeem hloov kho cov yam ntxwv thiab kho cov txheej txheem ntawm cov txheej txheem thermoplastic kom ua tiav kev kho yooj yim thiab txhim kho pob txha toughness txawm tias tom qab ntau yam kev puas tsuaj thiab kho.
Nws tau tshaj tawm tias qhov kev tsim kho yuav daws tau ntau qhov xwm txheej uas yuav tsum tau ua haujlwm niaj hnub thiab kho cov txheej txheem sib xyaw, tab sis nyuaj thiab tsis muaj tseeb kom ua tiav, xws li offshore cua turbine hniav lossis qee hom dav hlau. Cov txheej txheem yooj yim thiab scalable no tseem yuav raug coj los siv hauv kev ua kis las lossis Marine composite applications.
