Abstract
Unidirectional composite laminates usually present distinct behavior in tension and compression since compressive loads parallel to fibers may induce a wide range of failure mechanisms. There are several micromechanical models to estimate the longitudinal compressive strength of unidirectional laminae, however there is no agreement about which one is able to obtain the best estimation. In this paper, a comparative analysis is carried out evaluating seven analytical models and checking their predictions with experimental data. Results indicate that even the most accurate models have an average error higher than 20%, indicating the need of theories refinement.
