I've been looking for Spectra cloth for layup for the 5+ years without
success. What is available (that I've found) does not have the surface
etching suitable for composites. Unlike others, I never had a
delamination problem with my parts either, but I used compression
molding for my paddles.

The density is so low that you could use it instead of a core material.

Spectra fiber is made by Allied-Signal, now a part of Honeywell. You
may be able to talk with them about a sample.

The commercial aps don't seem to use it much in a composite form, and
the only ones which do, mention a proprietary resin system.

Other documentation mentions that most glues will not stick to it.

Another common use of Spectra fabric is in high-end racing sails.
Again, you may be able to talk with a company and buy a small
quantity.

Other fabrics, such as Kevlar, have variations specialized for use in
composite layup.

Happy trails,
