Effect of Fiber Angel of Unidirectional Longitude Fiber on Transverse Strength of Pultruded Polyester Rod

In this research by using a new technique which is named, Rotational Pultrusion, angular entrance of uni-directional (UD) fibers directly into the process was successfully reached. E-glass/polyester rods' samples pultruded with different fiber angles and testing them with three points bending. The test showed that with an increase in UD fiber angle, toward pultruded rod direction, finally the modulus and strength on transverse direction were increased.
