Size Effect of CaCO₃ Filler on the Mechanical Properties of SMC Composites

Abstract:

SMC composites consist of chopped glass fiber as a reinforcements, polyester and mineral fillers. Among them, filler is one of the important factors for improving mechanical and thermal properties of composites, but it has not drawn much attention for SMC composites. In this study, the size effect of calcium carbonate as mineral filler on mechanical properties of SMC composites was discussed using five different sizes of commercial calcium carbonates without chopped fiber reinforcement, to focus on the size effect itself. The SMC process was modified to be suitable for a laboratory scale composed of three steps. The mean sizes of the calcium carbonates were 3 – 20 μm, and the specific surface areas were calculated to be 1 – 5 m²/g by BET. Small size of calcium carbonate having high surface area up to 4 m²/g showed high thermal resistance, and showed higher strength comparing to the large fillers because it affected to form a dense packed microstructure.
