Lab task #7

ID tags on sample fixtures for Prof. Ucci

Continue building prototypes

Check 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. 

1. Determine if the ID markings are still readable.  Identify each bag with its epoxy name, if possible.

2.  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.

Prepare 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.

Open 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.

Continue prototype development.
