tags on sample fixtures for Prof. Ucci
the refrigerator samples, which are stored in mesh bags in
seawater. They are sorted so that one type of epoxy is used
on the fixtures in each mesh bag.
Determine if the ID markings are still readable. Identify
each bag with its epoxy name, if possible.
Attach new Tyvek/permanent ink marker tags around each mesh
bag to make it easier for Prof. Ucci. He will collect the
REF samples on Thursday, Oct. 25.
a set of new life test samples using Smart Glue (PSI-326)
on heavy aluminum fixtures for tension test and on oak wood
fixtures for compression tests. Apply the epoxy under seawater
in a tray. Note advice on complete coverage of the designated
area (2-inches X 2-inches); it is good to apply enough epoxy
so that you can squeeze a bit of the excess out. Clamp the
samples, if desired. Put the samples in a second minnow cage
and take outside and suspend from the floating dock. Make
a note of the water temperature.
the life-test samples in the first minnow cage and see if
any can be salvaged with positive ID's. If so, put them in
mesh bags with Tyvek tags with only one epoxy type per bag.
Put back in minnow cage. Remove samples without ID's. You
may be able to recognize the epoxy type by appearance to get
a positive ID if you can't read the ink labels.
