Paper Title:
Effect of Fiber Aspect Ratio and Area Ratio Getting to Accuracy of Intensity Method in Fiber Orientation Angle Distribution Measurement
  Abstract

Measurement of fiber orientation distribution state is very important constituent to find out decision of processing condition of product or mechanical special quality of moldings in fiber reinforced polymer composite material. Therefore, reliable measurement method of fiber orientation angle distribution is established, and need researcher about simplicity measuring method urgently the nondestructiveness. In this research, to investigate about accuracy of fiber orientation angle distribution measurement of fiber reinforced composite material by intensity method, find fiber orientation function value that is measure of fiber orientation distribution state constructing fiber orientation simulation picture by plotter changing diameter and length and orientation state of fiber. Recognize this fiber orientation simulation picture by image scanner, and measure fiber orientation angle distribution state by this realized intensity information. This time, I wish to measure reliable fiber orientation angle distribution comparing fiber orientation function calculation value saving in the advance with fiber orientation function value that is measured by intensity method. The results show that measurement accuracy of the fiber orientation angle distribution by intensity method is affected by the fiber aspect ratio when the total length of oriented fiber is same. The average gradient of fiber orientation function is 0.94 for 1000mm of the total fiber length and is 0.93 for 2000mm when the fiber aspect ratio is over 50. Measurement accuracy by intensity method is about 94% and the reliable data can be obtained by intensity method.
