A Novel Micromechanics-Model-Based Probabilistic Analysis Method for the Elastic Properties of Unidirectional CFRP Composites

Abstract: Considerable uncertainties in the mechanical properties of composites not only prevent them from having efficient applications but also threaten the safety and reliability of structures. In order to determine the uncertainty in the elastic properties of unidirectional CFRP composites, this paper develops a probabilistic analysis method based on a micromechanics theoretical model and the Monte Carlo simulation. Firstly, four commonly used theoretical models are investigated by calculating the deterministic elas… Show more

“…The Chamis model is a modified technique that substitutes the fiber volume fraction of the conventional simple ROM with the square root. Unlike the conventional ROM, it can measure the values of five effective properties, including G23, making this technique widely applicable [27][28][29][30].…”

“…[1][2][3] However, owing to the difficulty in accurately determining the fiber distribution and the volume fraction of each component in CFRP, the mechanical properties of CFRP are uncertain, which greatly limits its further application. 4 The CFRP laminates are fabricated by stacking layers of carbon fiber and matrix, and their bonding effect directly affects the properties of CFRP. The interlaminar shear performance is a common index to evaluate the bonding effect of CFRP.…”

“…The prediction on the structural performance unidirectional laminates due to the microscale spatial variability have also been studied [11,12]. The progress on the uncertainty analysis of the composites has been reported by researchers [13,14,15,16]. The second approach considers manufacturing defects to model the material variability.…”
