Transverse compressive properties of novel carbon/glass hybrid thermoplastic composite rods

Abstract

The transverse compressive properties and fracture behavior of the hybrid rods were investigated. The compressive load per unit length-displacement (F-U) curve showed large nonlinear behavior and complicated shape. In the initial stage, the load gradually increased with increases in the deformation. This behavior was caused by the increase in the contact zone. In the second stage, the load-displacement relation was almost linearly proportional to the displacement (stable deformation region). Subsequently, the slope dF/dU decreased slightly. Finally, the load-displacement curve showed a clear slope dF/dU increase as the deformation proceeds. The transverse compressive modulus and strength of the hybrid rods were ranged 639-655 MPa and 8.05-15.26 MPa.
