摘 要：<正> Theoretically;the strength of composite with branched fibers is predicted to be greater than that ofcomposite with plain fibers.The effects of the branching angle of the fiber,and the snubbing frictionbetween the fiber and the matrix at the fiber branching point and the branching step’s number of thefiber on the strength of the composite with branched fibers have been studied.It has been shownthat the strength of the composite increases with branching angle,the snubbing friction and thebranching step’s number.
