Abstract
In this study, the effect of varying weight percentages of carbon fiber powder (CFP) (10 wt.%, 20 wt.% and 30 wt.%) on the mechanical properties of polycarbonate (PC) components produced by plastic injection molding was investigated using analytical, numerical and experimental methods. This research is a novel study in terms of comparing experimental data with microscopic features and full-scale analysis. The micro-scale study was carried out using the Halpin-Tsai (HT) and Generalized Modified Halpin Tsai (G-HT) models as well as the representative volume element (RVE). Findings from RVE were then transferred to the finite element analysis (FEA) module for full-scale comprehensive analysis. A comparison of the experimental tensile test results demonstrated an increase of 56.90% and 191.47% in the tensile strength and Young’s modulus of the composite containing 30 wt. % CFP compared to pure PC, respectively. The minimum and maximum differences between Young’s modulus and the experimental Young’s modulus were determined to be 0.39% and 7.92% using RVE and G-HT, respectively. The maximum and minimum value of the difference between experimental and FEA strengths were determined as 3.44% and 1.91%, respectively. Young’s modulus of the composite with increasing fiber weight ratio was successfully predicted by RVE, G-HT and FEA.
期刊介绍：
This interdisciplinary journal provides a forum for presenting new ideas in continuum and quasi-continuum modeling of systems with a large number of degrees of freedom and sufficient complexity to require thermodynamic closure. Major emphasis is placed on papers attempting to bridge the gap between discrete and continuum approaches as well as micro- and macro-scales, by means of homogenization, statistical averaging and other mathematical tools aimed at the judicial elimination of small time and length scales. The journal is particularly interested in contributions focusing on a simultaneous description of complex systems at several disparate scales. Papers presenting and explaining new experimental findings are highly encouraged. The journal welcomes numerical studies aimed at understanding the physical nature of the phenomena.
Potential subjects range from boiling and turbulence to plasticity and earthquakes. Studies of fluids and solids with nonlinear and non-local interactions, multiple fields and multi-scale responses, nontrivial dissipative properties and complex dynamics are expected to have a strong presence in the pages of the journal. An incomplete list of featured topics includes: active solids and liquids, nano-scale effects and molecular structure of materials, singularities in fluid and solid mechanics, polymers, elastomers and liquid crystals, rheology, cavitation and fracture, hysteresis and friction, mechanics of solid and liquid phase transformations, composite, porous and granular media, scaling in statics and dynamics, large scale processes and geomechanics, stochastic aspects of mechanics. The journal would also like to attract papers addressing the very foundations of thermodynamics and kinetics of continuum processes. Of special interest are contributions to the emerging areas of biophysics and biomechanics of cells, bones and tissues leading to new continuum and thermodynamical models.
