Interfacial component of glass fiber in ternary composites of GF/PC/PP: effect of the preferential encapsulation of glass fiber
We investigated the encapsulation phenomena of glass fibers for a ternary composite system of glass fiber, polycarbonate and polypropylene by impregnating fibers with a selected resin using a newly developed process. On the basis of our observations of the morphology and mechanical properties, we report that viscosity ratio may very likely play an important role in the final interfacial structure of this system and that the improved wetting of fibers by preferential encapsulation would be a good approach in cases where the combinations of the resins or processing conditions lead to the similar relative melt viscosity of the component resins.
