This paper addresses the problem of predicting the behaviors of a composite material, which consists of a matrix phase and an ellipsoidal reinforcement coated by a multi-layered interphase, under one or more of the hygral, thermal and mechanical loading conditions and based on the micromechanics principles.
After the cloth strips and lacquer are applied for reinforcement, coats of an intermediate, hard and dark lacquer are brushed on to the piece.
We conducted comprehensive molecular dynamics simulations of the nanoindentation of graphene reinforced composites to study the effect of graphene as a reinforcement and coating material.
The results of this study demonstrate that bamboo-composite reinforcement without coating develops adequate bonding with the concrete matrix.
In particular, four different reinforcement methods with mortar coating (bare mortar coating, coating with steel mesh, coating with polymer reinforcement, and coating with GFRP mesh reinforcement), three different mesh-only reinforcement (steel mesh, polymer mesh with larger grids, and polymer mesh with smaller grids), and 2 different arrangements of PP-bands (4 × 4 and 6 × 6) were tested.
Taguchi design of experiment (DOE) methodology was used to analyze the influence of the HVOF spraying conditions (% SiCp in feedstock, spraying distance, number of layers and gun speed) in the main characteristics of the coatings (actual amount of reinforcement in the coating, porosity and thickness) and in some properties of the coatings such as hardness and adhesion.
Silica nanoparticles, on the other side, increase the density and provide a major mechanical performance through the reinforcement of the coating.
However the requirement of metal mesh into mortar coating reinforcements is quite empirical.
A reaction between B4C and Ti occurred, leading to an in-situ synthesis of TiB2 and TiC reinforcements in the coating.
The effect on residual stresses of the reinforcement particle (B4C) content, coating thickness and porosity of Al Si/B4C coatings on Al Si alloy substrate were investigated by the finite element method (FEM).
The traditional method of galvanizing by hot dipping and the recent development of continuous coating of reinforcement will be discussed, and differences in the morphology of the zinc coating will be explained.
