Paper Title:
Study on the Fiber Distribution and Fiber Orientation in Low Pressure Sheet Molding Compounds
  Abstract

LPMC specimens were burned in an oven at 500oC for 3h to obtain the fiber images by a scanner. The fiber distribution and orientation was analyzed using MATLAB software. And the effect parameters and controlling methods on fiber orientation and mechanic properties of molded parts were studied, too. Results showed that when the viscosity of LPMC sheet was 5×106cp , the feeding area was 60% and the velocity of mould closing was 1.0 mm/s, the uniformity of fiber distribution was optimum. And proper velocity of mould closing (1.0 mm/s) could decrease the fiber orientation. In addition, the flexural strength (185MPa) and flexural modulus (14.2GPa) of LPMC specimens paralleled the fiber direction were much higher than vertical one (75.2MPa, 6.9GPa).
