High Resolution & High Magnification CTF3 Submission Images

A few people have asked me to provide higher resolution images of Cuben samples that I test. As I have mentioned previously, regardless of the resolution that I post to the forums, my images are reduced to 550 x 413. Occasionally I will supplement the images posted to the forum with my images posted to another site in order to maintain their original resolution.

This initial high resolution image set is from Dave Olsen's submission 23 virgin sample. It is Breen colored CN2K.08.

Submission 23's CTF3's (Cuben) surface appears similar to all other CTF3 submissions. To the naked eye or at low magnifications, the Mylar appears smooth. As the magnification increases, the shallow indentations and valleys in the virgin Mylar surface material become easier to see.

All of the images I post to the external site 1600x1200 resolution with no compression. The magnification ranges are 40x, 100x, and 400x. As you single left click the image its magnification will increase until the screen is completely filled with the image. At this point you will be at that site's maximum resolution of 1520 x 1100 pixels.

I also encluded high resolution image set for Submission 11B Aged which is CT1K.08. This will give you a general idea of how the Mylar surface degrades with aging for most CTF3 submissions.

Supplemental information from Richard Nisley: The sample appeared to have been carefully handled with no visible crinkle marks.

This submission size is too small to cut into two pieces for an aging sample. The virgin copy will be submitted to Roger Caffin as part of batch 2 but will not be aged by me.

If you have been keeping up with the forum concerning Protocol B, Batch 1 and 2 Test Results you see data that has been generated needs further exploration if a thorough understand can come about...

Some items that would aid in the understanding and processing of the Cuben Fabrics data now undergoing HH Testing by Richard would be:
• The dates these fabrics were manufactured.
• What was the width of roll the fabric samples came from?
• Does Cubic Tech have different grades of Cuben?
• Were any of the Cuben sample tested silicone-coated?
• What QC checks are routinely done by Cubic Tech and the manufacturers buying their products?

I think answers to the questions above would aid Richard in his quest for additional information for the understanding and processing the Cuben data and why some tests are demonstrating positive attributes as other are not. If you can aid with any of the above questions may I ask that you send your feedback directly to Richard.

Q-IS NANO-TEX FABRIC PROTECTION WATERPROOF?

A-Nano-Tex Resists Spills fabrics are NOT considered waterproof nor would they be considered a barrier product but Nano-Tex Resists Spills fabric are a superior repellant technology.

Supplemental information from Richard Nisley:
This material would not typically be considered a light weight shelter material. I measured the air permeability at 38.2 CFM and the thickness at .26 mm.

The fabric weave voids in this material only were too far apart at 200x magnification from below to see a set of illumination points. I submitted an extra micrograph as was required for this unique fabric weave.

It is easiest to see the pore structure of this material from a 60x top lit position. Even to the naked eye, the construction looks like a lot of granules glued together and you wonder if water will leak through... it won't.

Submissions still in the Protocol B submission queue will be promptly processed by me as I receive them. After completing the pending submissions and negotiating the details of the batch 2 aging procedure with Roger Caffin, my participation in submission testing is complete. Thank you to the many folks who provided Protocol B submissions as well as reporting DIY testing.
