What is Energy-absorption Properties of Braided Composite Rods about?

Braiding has been attracting a great deal of attention as a technique for manufacturing preforms for composite materials. It has been developed as an integrated braiding technique which permits the fabrication of near-net-shaped preforms for 3-dimensional composite materials with reinforcing ®bers oriented continuously. A braided rod is a simple unit of a 3-dimensional near-net-shaped composite. From this point of view, crushing tests have been performed in order to evaluate the braided rods. The speci®c energy absorption (Es) values of this material were higher than that of glass-cloth/epoxy tube. In this paper, we have tried to apply a ̄exible interphase concept to braided rods in order to obtain superior energy absorption properties. Braided composite rods with a ̄exible interphase also showed the characteristic crushing mode called progressive crushing. Consequently, the speci®c energy absorption of the rod with a ̄exible interphase was 30% higher than that of a composite without a ̄exible interphase. The fracture mechanisms of both materials are discussed with reference to microscope observations of crushed samples.
