Data taken or inferred from references as indicated. *For unannealed fibre. #For annealed fibre. Worst case scenario, real value likely to be much lower. ~Likely due to the polymer coating on the silica fibre, not the silica itself. Note that the response may also depend on the details of the fibre structure.
