Although many factors, such as the porosity, number of bonds,
orientation, etc., affect the fiber network properties, the mechanical
properties indicate the degree of fibrillation. The fiber network
of the bleached carrot residue had strength of 178 MPa, which is
high compared to the bleached BSG at 59 MPa. The modulus of the
bleached carrot residue network is increased significantly with the
grinding process from7.6 to 12.9 GPa and thefinal strength was also
very high at 210 MPa. Also a considerable increase in the mechanical
properties was observed for BSG after the fibrillation process,
the strength increased from 59 to 139 MPa and the modulus from
4.1 to 9.9 GPa. The maximum strain of the nanofiber networks was
slightly decreased with the fibrillation for the carrot nanofibers
but increased for the BSG network. However the carrot nanofiber
network showed higher strain than the BSG network.
