PROBLEM TO BE SOLVED: To prepare a polypropylene resin crosslinking foamed sheet maintaining sufficient buffer properties without being crushed or torn and having good adhesive processability with the other composite materials even when the sheet is subjected to hard fabrication, and to provide a preparation method of a laminated foamed particle molding using the foamed sheet by a skinmold molding method. SOLUTION: This polypropylene resin crosslinking foamed sheet is a foamed sheet using a polypropylene resin as a base resin, the storage modulus of the foamed sheet in a tensile measure is 3×10<7> -3×10<8> dyn/cm<2> at 50 deg.C, 1×10<7> dyn/cm<2> or more at 100 deg.C, 1×10<6> dyn/cm<2> or more at 130 deg.C, 4×10<5> -6×10<6> dyn/cm<6> at 140 deg.C, and tanδ(loss modulus/storage elastic molulus)=0.05 or more at 50 deg.C, 100 deg.C, 130 deg.C and 140 deg.C. |
