초록

In this study, a MMA modified polymer mortal sandwich panels was developed : Core was made with the MMA modified polymer mortar whose compressive strength was about 1020 kgf/cm$^2$, and both facings were made with the glass fiber reinforced plastics (GFRP). The results showed that the strain energies increased 20-33 times, respectively, as the thicknesses of facings increased from 1.50 to 2.76 mm with fixing the core thickness to constants (30-50 mm). On the other hand, these values showed a tendency of decrease as the core thickness increased regardless of thickness of facings. A set of basic data for the structural analysis could be provided by investigating the correlations, within the scope of this research, between the resisting moment and the thicknesses of core and facings.
