Description

A carbon fiber reinforced Nylon 66 was molded by a typical injection molding machine. The average fiber length and the breadth distribution of the length were examined in detail as a function of the fiber content or the injection conditions.<br>The fiber length became shorter with an increase of the fiber content. It is considered that the breaking of the fibers is mainly caused by the interference of the fibers, and the increase of viscosity. An increase in the injection speed led to considerably shorter fiber lengths. This is considered to be due to an increase in the shearing force with increasing flow speed of the resin. In these cases, the breadth of distribution of the length decreased slightly with decreasing length. On the contrary, the extent of decrease in fiber length became small with an increase of screw speed, and the breadth of the distribution remained nearly constant.
