Metal panel assembly and method for making same

摘要

The present invention discloses a metal panel assembly comprising:
a first metal panel (10) having a first body portion and a first flange (12) along a margin of the first body portion adjacent a first end (13) of the first body portion;
a second metal panel (20) having a second body portion and a second flange (22) along a margin of the second body portion adjacent a second end (23) of the second body portion;
an adhesive sheet (30) having a first portion (32) near a first end (31) of the adhesive sheet and a second portion (34) near a second end (33) opposite to the first end of the adhesive sheet;
said second flange of said second panel extending over said first body of said first panel with the second end of said second panel adjacent to said first flange of said first panel;
said first flange of said first panel being folded over said second flange of said second panel;
the first portion of the adhesive sheet being between and adhering said second flange of said second panel and said first body portion of said first panel;
the second portion of the adhesive sheet being folded over said second flange of said second panel and adhering said first flange of said first panel to said second flange of said second panel;
wherein the adhesive sheet comprises the thermoset reaction product of a melt-flowable and thermosettable composition that comprises an epoxy material and a thermoplastic polymer having one or more functional groups capable of reacting with an epoxy.
