Abstract
Flexural creep deformation behavior of an injection-molded short fiber composite material has been investigated with an emphasis on its anisotropy, stress dependence and temperature dependence. Three-point bending creep tests are conducted on test specimens with different orientations oblique from injection direction at room temperature and high temperature, respectively. It is shown that the creep deformation at room temperature develops more markedly with the increase in off-axis angle from 0° to 90°. The creep deformation increases as creep stress increases, regardless of the off-axis angle of specimen. It is also observed that creep deformation turns to be more significant at high temperatures compared with that at room temperature. A phenomenological model has been developed to describe the orientation dependence, stress dependence and temperature dependences of the observed creep deformation behavior. It is demonstrated that the flexural creep deformation behaviors of short fiber composites at different temperatures can adequately be described using the proposed model. It can be used to identify the flexural creep rupture stress associated with any specified flexural creep strain by means of the creep model established.
