240 Green Composites from Natural Resources
reinforcement of jute ber in NR and styrene–butadiene rubber, respectively. It was
reported that for synthetic ber such as polyester and nylon an aspect ratio of 220
and 170 gives good reinforcement in NR vulcanizates, respectively (Holbery and
Houston 2006; Murthy and De 1982).
10.9.5 fiBer orientation
Fiber orientation has a signicant inuence on the physicomechanical proper-
ties of ber-reinforced rubber composites. The preferential orientation of bers in
the matrix results in the development of anisotropy in the matrix. With respect to
orientation, three limits are explained as longitudinal (along machine direction),
transverse (across machine direction), and random. It was observed that du ...
