The benefits of using Design of Experiments (DOE) for determining effects of critical factors are significantly greater than using one-at-a-time experimental techniques. The volume and validity of the information gained from DOE, especially for manufacturing processes, is very high due to the strong statistical basis of the method and highly organized nature of the results. The use of DOE is described in the case of injection molding of composites to improve and better understand the effects of critical factors on the physical properties of the finished parts. The factors, fiber length, fiber concentration, part temperature, and mold thickness, were tested using a full factorial experiment. The results demonstrated the significance of the factors and their interactions on tensile strength, modulus of elasticity, and elongation.
