The shish-kebab structure consists of long central fiber core (shish) and lamellar crystals (kebab) periodically attached along the shish structure. It is believed that the shish structure is a molecular basis of ultra-high modulus and ultra-high strength fiber. In this experiment, we focused on the role of various molecular weight components in shish-kebab structure. We used the several neutron scattering spectrometers in order to observe the precise shish-kebabs in a quite wide spatial range from nm to micron. The low molecular weight component could be stretched easily and then composed nm-cylinder mainly. We will discuss about the precise model of shish-kebab structure in various molecular weight components.
