TL;DR: In this paper, the authors used the homogenization method to characterize the mechanical behaviors of a solid-fluid mixture by using the method of asymptotic expansions, which is based on the localization.

TL;DR: The use of Raman spectroscopy to investigate micromechanical properties of laminated bacterial cellulose (BC)/poly(l-lactic) acid (PLLA) resin composites is reported for the first time as a means for understanding the fundamental stress-transfer processes in these composites, but also as a tool to select appropriate processing and volume fraction of the reinforcing fibers.
Abstract: Understanding the nature of the interface between nanofibers and polymer resins in composite materials is challenging because of the complexity of interactions that may occur between fibers and between the matrix and the fibers. The ability to select the most efficient amount of reinforcement for stress transfer, making a saving on both cost and weight, is also a key part of composite design. The use of Raman spectroscopy to investigate micromechanical properties of laminated bacterial cellulose (BC)/poly(l-lactic) acid (PLLA) resin composites is reported for the first time as a means for understanding the fundamental stress-transfer processes in these composites, but also as a tool to select appropriate processing and volume fraction of the reinforcing fibers. Two forms of BC networks are investigated, namely, one cultured for 3 days and another for 6 days. The mechanical properties of the latter were found to be higher than the former in terms of Young’s modulus, stress at failure, and work of fracture....

TL;DR: In this paper, a new micromechanical model for the prediction of the tensile modulus and strength of natural fibre reinforced polymer matrix composites is presented, which addresses issues linked to the statistical variation inherent in fibre reinforcements extracted from plants.
Abstract: This paper presents a new micromechanical model for the prediction of the tensile modulus and strength of natural fibre reinforced polymer matrix composites. The model addresses issues linked to the statistical variation inherent in fibre reinforcements extracted from plants. The new model introduces a fibre area correction factor (FACF). Modulus and strength are estimated and compared to experimental data for a jute-epoxy composite. The predictions of tensile modulus and strength using the FACF show improvements over those from other micromechanical models presented in the literature.

TL;DR: In this paper, a micromechanics-based elastic model is developed for two-phase functionally graded materials with locally pair-wise interactions between particles, and the effective stiffness distribution over the gradation direction is further derived.

TL;DR: In this article, an analytical method called the selective averaging method (SAM) was proposed for prediction of the thermoelastic constants of textile composite materials, where the unit cell of the composite is divided into slices (mesoscale), and the slices are subdivided into elements (microscale).
