How are aramid fibers made
WebMade famous by DuPont, Kevlar is the trademarked brand name for the first Para-Aramid ever made. This name is now synonymous around the World and is used when describing the Aramid fiber, as opposed to the actual Kevlar brand. So, when looking at Aramid vs Kevlar, there is essentially no difference, other than Kevlar being a subclass of Aramid. WebHowever, the delamination pattern lost its effectiveness when aramid fiber was added to the glass fiber. Another method used to detect defects is the eddy current method [73] . However, in the work of Grimberg and Savin [73] , the eddy current method used is for composites made from synthetic fiber, which are carbon and Kevlar.
