For example, fixing\ Ro/w】an Atk\inson】’s McL\aren F1 with \all of its carbon fibre part【s 】is thou/g【ht【 to h】av\e been the largest ever vehicle】 insurance pay-out in UK his\】tory at &po/und;910,000.Wonder/ material from【 recycled c】lo\thi【ng 【Voir\ cett【e public】ation】 sur Instagram】U/ne publication partagée par Faraday Fut\ure \(@fa】radayfutu\re) le 27 /\Juin 2018 &/ag【【rav\/e; 11 :27 PDTToday, we find carbon\ 【fibre in u\se a】cross many\ mainstream cars,/ tho\ugh/ it tends to【 b\e us/ed in str\ategic areas whe\re\ stren】gth and lightweight materi/als【 ar【e cr【uci【al.

By bre\aking th】e materials down\ to t【heir】 /molecular\ 】leve/l】, it&r】squo;s possible to re-\engin/e】er them in】to carbon f】ibr/e.Related |If you c/ou/ld】 fly cl\eanly, would you?R】odrigo Caula/, a \material designer at Faraday, e/xplai【n/s: "【It sou】nds like science fiction\, but it’s happ/】ening now.
