Abstract

As the new composite connection technology, pre-tightened teeth connection can play better mechanical performance for composite materials. To this connection technology, the ultimate bearing capacity of the first tooth is very important. In this article, the ultimate bearing capacity of the single tooth is researched by the experiment and theory. Firstly by the experiment, the optimal tooth depth and an effective teeth length are obtained. Secondly on the basis of reasonable simplified load model of a single tooth, the theoretical solution of the interlaminar stress distribution on a single tooth is worked out. And depending on the interlaminar stress distribution theory, the concepts of optimal tooth depth and tooth length are explained and their determination methods are given out. Finally combined with tests, the approach to determine the ultimate bearing capacity of the single tooth is put forward, hence offering design method for the final connection.
