On the treeing characteristics in the interface of FRP

Abstract

Electrical treeing characteristics of fibreglass reinforced plastic (FRP) have been investigated on a set of specially made samples with a single-core glass fibre. It is pointed out that the direction of a glass fibre at an angle of /spl Theta/ with the electric field and the diameter of a glass fibre have significant effects on the initiation and propagation of tree in the interface of FRP. The morphology of tree and mechanism of treeing in samples were discussed.<>
