PRODUCTION OF SANDWITH PANEL FITTED WITH INSERT

摘要

PURPOSE:To prevent the damage of lightweight properties by suppressing an increase in the wt. of a filler even in a sandwich panel having large thickness by inserting an insert in a sandwich panel so as to crush the skin and core material of a part surrounded by a notch and filling the periphery of the insert with the filler to fix the insert. CONSTITUTION:A ring-shaped notch 7 is formed to a sandwich panel 1 by machining. Next, the skin 1f and core material 1g of the part surrounded by the ring-shaped notch 7 are crushed and an insert 3 is inserted in said part and the periphery of the insert 3 is filled with a filler 4 and the filler 4 is cured to attach the insert 3. The filler 4 in the periphery of the insert 3 attached to the sandwich panel 1 is interrupted by the skin if of the crushed part to be prevented from filling the core material 1a under the insert 3.
