I was bored, so in 30min, I through together a test panel with about 8 layers of spectrashield 3124, and offset layered 2 plys of 24oz carbon, with LDPE face sheets, split in half.
You can see that when the hologram is on the outside of the LDPE layer, it’s clear and perfect. If UNDER the LDPE layer, it’s not really visible as a hologram. (as shown in the second pic. that is where the hologram went under the film layer) Slightly disappointing since I wanted to embed the hologram IN the composite, not just laminated on top. Eh.
Hologram samples provided by www.intlam.com and Ray Horan. Great guy!
