Compressive properties of UHMWPE fiber composite vs. tensile.
Compressive properties of UHMWPE fiber composite vs. tensile.
(OP)
I have been looking into ultra high molecular weight polyethylene (UHMWPE) fibres and haven't found much on the web about their properties in composites. I'm aware that they are hard to stick to, but I'm still interested in composites made from them.
Does anyone have any experience of polymer matrix composites with these fibers? (I believe Spectra and Dyneema are the only options at present.)
I'm particularly interested in how the compressive properties stand up compared with the tensile ones, so a property value for an all-0 degree laminate would be good. (Compression seems to be a bit of a bugbear for these organic fibers, with Kevlar, PBO, M5, etc., all having poor basic fiber properties in compression.)

I saw a fishing rod made from Kevlar/epoxy once. It was made just to see what would happen. It behaved like ductile steel. If you bent it, it stayed bent.

Anyone have more than rumours of M5's properties? I notice their website has changed, and I heard they've been due to start a pilot plant for a while.
