Sample
preparation task #3, by E. Sichel on Feb. 1, 2002.
Shown
above are 20 pieces of stainless steel, 0.031-inch X 1.5-inch
X 6.0-inch. The adhesives were applied on a 1.5-inch by 1.5-inch
overlap area and the adhesive bond will be tested in tension
mode. The stainless steel was cleaned with Scotch-Brite soap
pads in hot water, rinsed, and dried. The control samples
were cured in air. The experimental samples were prepared
in air on the bench. They were left to dry for 15 minutes,
and then immersed in a tray of seawater and stored, in the
covered tray, in the refrigerator at 34 degrees F.
The
adhesives used in this test of strength of the adhesive bond
are:
Aquamend,
two-part epoxy
PSI-326,
two-part epoxy
3M
Co. Marine sealant 5200
3M
Co. FastCure 5200
3M
Co. FastCure 4200
The strength of the adhesive bonds of the
life-tested samples in seawater will be measured by Prof.
Ucci's engineering students at Bristol Community College.

Inspection
Report
On
Feb. 19, 2001 the samples were removed from the refrigerator
after 18 days at 34 degrees F. The samples were left in
their sample trays in seawater. They were then stored at
about 45 degrees F in their seawater trays for 24 hours
for delivery to Prof. Ucci on Feb. 20, 2002. |
