Hi,
I an considering building a kind of lean-to out of epoxy, carbon fibre tow and glass fibre cloth.

Imagine an L shaped wall 4.7m by 2.5m, you are standing square in front of the long side and the short side is to your left, the wall is 2.3m high. To your right is the house with a flat roof, eaves at 3.9m.

Now imagine I loop carbon fibre tow from pegs mounted on top of the walls up to a hook on the house wall at about 3.2 - 3.8m high. So far I think I understand what to do.
Add epoxy to the tow, wind more threads across primary 'beams'. Consider CF braid over synthetic rope/twine. Gather three almost crossing threads to a point for a more organic look. Consider adding upwards curvature to have loading push rather than pull on the mounting points.

The next step is the tricky bit. I think that, once cured, the skeleton can be lifted off the wall + hook and a surface layered on to the skeleton at ground level.

How to create a waterproof translucent but not necessarily see-through surface?

1. 320gsm biaxial glass reinforcement and UV safe epoxy resin lay up between the 'beams', possibly cut to shape.
2. Clear polycarbonate sections cut to shape and fixed to the beams with epoxy or VHB adhesive tape.
3. Any other ideas?

Comments and 'watch out for' hints are most welcome as is product selection part numbers etc.

Thanks,
Guy.
