    The fibrous filler in the molded parts lies generally in same direction to a certain extent. This phenomenon easily occurs in the injection molding of the recently developed Bulk Molding Compound (BMC), which is a serious problem in applying this high-productive molding method. So, in order to clarify the fiber orientation phenomenon in injection molding of BMC, the effects of molding conditions and mold geometry on the fiber orientation were investigated, kneading the optical fiber composed of lead compound and taking the X-ray photograph of molded parts. Different fiber orientations occur in three regions in the molded parts; fiber lies coaxially in the vicinity of gate, perpendicular to the direction of injection and parallel to the cavity wall opposite to gate. The coaxial fiber orientation in the vicinity of gate becomes ellipse whose major axis coincides with the direction of injection at low mold temperature.

    This paper describes verifications of Chen's approximate solutions for web stiffened sandwich constructions by means of photoelastic experimental study. Also it is concerned with derivations of a developed analysis for web and soft core. Considering the sandwich constructions as a Vierendeel Truss, the developed solution can present the second-order shear modulus μ* determined by measuring local bending effect, which accounts for the transverse shear deformation of the webs and soft core. While retaining the discrete nature of the webs and soft core, the flexural formulus using μ* could be based upon the energy principles of continuum theory due to the replacement by a “smeared-out” homogeneous layer. In addition, the validity of the solution was examined by comparison of the results from rigid frame and truss analysis. The photoelastic experimental results obtained are in good agreement with the analytical solutions. The optimum face thickness and web spacing for sandwich construction with web and soft core were cleared.
