The main objective of this study is to create a rigorous computer model of carbon nanotube composites to predict their mechanical properties before they are manufactured and to reduce the number of physical tests. A detailed comparison between experimental and computational results of a cement-based composite is made to match data and find the most significant parameters. It is also shown how the properties of the nanotubes (Young’s modulus, aspect ratio, quantity, directionality, clustering) and the cement (Young’s modulus) affect the composite properties. This paper tries to focus on the problem of modeling carbon nanotube composites computationally, and further study proposals are given.

Prediction Of Mechanical Properties

Carbon nanotube (CNT) composites have mechanical, thermal, and electrical properties superior to those of conventional polymer resin materials. In particular, multi-walled carbon nanotube (MWCNT) composites have higher mechanical strength than single-walled carbon nanotube composites. This work investigates the methods for analytically evaluating and predicting the mechanical properties of MWCNT-reinforced nanocomposites to enable their effective mechanical design. First, the correlation between the thickness of the interphase region (between the carbon nanotubes and the polymer matrix) and the mechanical properties of the MWCNT-reinforced composite was studied. Next, the effect of the relative distribution of carbon nanotubes in the matrix on the mechanical properties of nanocomposites fabricated by injection molding was evaluated. Finally, the effect of agglomerate size on the mechanical properties of nanocomposites was investigated, and a critical size for carbon nanotube agglomerates was analytically proposed.
