Glass flexible / plastic stringers

Tests of different formulations.

PVA melting. Did not work. PVA became soft, but started burning without becoming liquid.

PVA water soluble film. Add 15 g film (~ two layers), add water to dissolve (around 100 ml, did not measure), stirred 5 min, it nearly all went into solution, viscosity was low. Add 15 g glass powder, heat on hot plate at 60C until water evaporated.

PLA dissolved in DCM (dichloromethane). Added 15 g PLA pellets to DCM, ~100-150 ml.

Higher mol weight PVA + CMC.
ABS in acetone
