Abstract :
Trees in silicone rubber has been investigated using 2-D specimen. The tree is classified two, i.e. 1st and 2nd tree. The behaviors of these trees have been observed by changing the ratio of two components of silicone rubber. The 1st tree is usually linear but the bubble has been formed in the soften silicone rubber. When the 1st tree is round babble, it is difficult for the 2nd tree to start from it. The speed of the 2nd tree in harden silicone rubber is higher in harden silicone rubber. The mechanism of tree in silicone rubber can be considered, and the pressure inside the tree is suggested to be important factor.
