Method for producing FRP sandwich structure and FRP sandwich structure

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an FRP sandwich structure in which an FRP sandwich structure having excellent adhesive strength and high dimensional accuracy in a thickness direction can be obtained.SOLUTION: After first and second FRP skin material 101, 102 each having a plurality of through-holes are molded, the first FRP skin material 101 is mounted on resin 82 for adhesion which is coated on one surface of a foamed core material 103, which is decompressed in a hermetically sealed state. Thus, the foamed core material 103 and the first FRP skin material 101 are adhered while air bubbles 84 in the resin 82 for adhesion are discharged via the through-holes 101a of the first FRP skin material 101, and the second FRP skin material 102 is adhered to the other surface of the foamed core material 103 in a similar manner.SELECTED DRAWING: Figure 7
