Kevlar linear polyethylene

Both Kevlar (Section 5.7) and extended-chain linear polyethylene (Section 5.6) fibers contain a high degr of extended-chain crystallinity, yet the former is somewhat stronger than the latter. Why ... [Pg.52]

There have been no similar attempts to determine comprehensive sets of elastic constants for oriented fibres or monofilaments. Kawabata [21] devised an apparatus that used a linear differential transformer to measure diametral changes of 0.05 iim in single fibres of diameter 5 fxm subjected to transverse compression. Equation (7.2) above was then used to calculate the transverse modulus El = l/ ii. Results were obtained for poly(p-phenylene terephthalamide) (Kevlar) and high-modulus polyethylene (Tekmilon) fibres. Values of E were in the range 2.31 -2.59 GPa for Kevlar and a value of 1 -2 GPa was found for Tekmilon. [Pg.137]
