Tsis tas li ntawd, los ntawm kev txhim kho keeb kwm ntawm kev tshawb fawb carbon fiber hauv Suav teb, kev khiav ntawm cov kws tshaj lij thev naus laus zis feem ntau yog qhov tseem ceeb cuam tshuam rau R & amp; d qib ntawm ib lub koom haum tshawb fawb. Kev tswj xyuas qhov kho ntawm cov kws tshaj lij thiab R & amp; d pab pawg hauv cov txheej txheem tsim khoom, cov khoom sib xyaw thiab cov khoom lag luam tseem ceeb yog qhov tseem ceeb rau kev hloov kho tshuab txuas ntxiv.

Peb yuav tsum txuas ntxiv ntxiv dag zog rau kev cob qhia thiab siv cov neeg ua haujlwm siab tshaj plaws hauv daim teb no, txhim kho kev soj ntsuam thiab kev kho txoj cai rau Technology R & amp; d txuj ci, ntxiv dag zog rau kev cog qoob loo ntawm cov tub ntxhais hluas cov txuj ci, nquag txhawb kev koom tes thiab kev sib pauv nrog txawv teb chaws advanced R & amp; d cov tsev kawm ntawv, thiab nquag qhia cov txuj ci siab txawv teb chaws, thiab lwm yam. Qhov no yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev tshawb fawb carbon fiber ntau hauv Suav teb.
