In this paper, adding multiwalled carbon nanotubes (MWCNTs) to the polymethylmethacrylate-based (PMMA) bone cements as a way of reinforcement were prepared, and the structure was investigated. The aim of this study was to confirmed the transverse-direction fracture toughness (KIv) in bone cement. TheKIvof PMMA cement and PMMA/MWNCTs cement were determined to be 1.32±0.1 MPa m1/2and 1.96±0.1 MPa m1/2, respectively.

This work reports the effect of multiwalled carbon nanotubes on mixed-mode I/II interlaminar fracture toughness ([Formula: see text]) of unidirectional carbon fiber/epoxy composite laminates made by prepregs. The carbon fiber/epoxy laminates were fabricated in an autoclave with a previous deposition of different multiwalled carbon nanotube contents at their middle plane interface by spraying technique. Mixed-mode bending tests were conducted on carbon fiber/epoxy laminate specimens under different mixed-mode ratios. The results of mixed-mode bending tests showed that the addition of multiwalled carbon nanotubes can effectively improve the [Formula: see text] of carbon fiber/epoxy laminates. With a 0.2 wt.% multiwalled carbon nanotubes content in carbon fiber/epoxy laminates, the [Formula: see text] under mixed-mode ratios of 0.2, 0.5 and 0.8 increased by 25%, 12% and 19%, respectively. These results were explained in terms of the damage mechanisms observed at the fracture surfaces of tested specimens by scanning electron microscopy.

Properties Of Composites

In this study various composites based on the commercial ethylene vinyl acetate polymer matrix and multiwalled carbon nanotubes were prepared by casting from solution in the form of thick films. The degree of dispergation of carbon nanotubes in the polymer matrix was examined by scanning electron microscopy. Electrical conductivity and mechanical properties of those composites were investigated. It was observed that the electrical conductivity of composites increases with an increase of multiwalled carbon nanotubes content. The mechanical properties of composites were only slightly changed when compared with properties of neat ethylene vinyl acetate matrix.
