Interesting, as in sailing we have kevlar sails, but spectra lines.

No, and spectra is way too expensive to use for deck lids, fenders... It is in a lay up.

Probably not needed in typical Sailplane crashes...

Spectra is a brand name for aramid fibers better know by another name: kevlar. I believe kevlar is used in the cockpits of the "safety cockpit" Schleicher gliders and probably others. A mix of carbon/kevlar seems to be common in the seatpans of new gliders these days.
