130 微細繊維状粒子分散光硬化樹脂の伸張流れ(S34-2 複雑流体の流れとその応用(2),S34 複雑流体の流れとその応用)  [in Japanese] 130 Extensional flow of photopolymer dispersed with fine fibrous particles  [in Japanese]

The elongational flow and solidification of particle-dispersed photopolymers has been investigated. Capillary thinning and solidification were observed. It was found that solidification produced a wavy instability on the liquid bridge of photopolymer. Transient diameter profiles in elongation were compared with the prediction for Newtonian fluid. A new application related to the experimental results was discussed.
