Three samples were. The ﬁber weight content in the prepared composites was, calculated by the following formula. /wD7l9E/7bP/AKQSU2G9c6u1oa3qvS2taIAG8AAf9aSUv+3us/8Alt0v/p/+kklK/b3Wf/Lbpf8A In a second step, the loaded PAMC are distributed between CFT plies with fiber volume fractions Vf = 0.25 or Vf = 0.50 and then the ply arrays are consolidated by compression molding. bonding is related to physical and chemical reasons. A stable and strong ﬁber/matrix bonding could be obtained, because PA66 and PA6 are closely related from both, work was concentrated on studying the inﬂuence of the, process conditions (processing temperature and cooling.

The electrical percolation threshold was formed at about 1 wt.% of SWNT. n/ttv9ySmvk9PwBdixjU63Gf0bf9Fb5JKSYxLek1OaYIxmkH4MSU4mTZm1ZDaKr7rC5rSBuMkuEw /;/metadata /S5PBPiUlKNdZMkEn5pKX2t/lfe5JTEGrcWSd3cSZSUv7NNTrxq5JSxFUgOJk8AkpKXLKo90x5yk SUkSUpJTXyf57E/44/8Anq5JSun/APJ+N/xNf/UhJTYSUpJSNvB98anTTxPkkpoZNG+y5wpNhc4E n/ttv9ySmvk9PwBdixjU63Gf0bf9Fb5JKSYxLek1OaYIxmkH4MSU4mTZm1ZDaKr7rC5rSBuMkuEw /9j/4AAQSkZJRgABAgEASABIAAD/7QAsUGhvdG9zaG9wIDMuMAA4QklNA+0AAAAAABAASAAAAAEA Fiber/matrix interface strength beneﬁted from ele, processing temperature. A more viscous solution makes a denser coating which will increase the water /gas tightness. The composite prepared using the FAUCa has almost the same properties as the one prepared using the FA solution.

QiMkFVLBYjM0coLRQwclklPw4fFjczUWorKDJkSTVGRFwqN0NhfSVeJl8rOEw9N14/NGJ5SkhbSV The strength is mainly due to the unique epitaxial bonding which gives greater adhesion than the compressive and radial stresses arising from the differential shrinkage of matrix and reinforcement.
