With the initial permeability testing technique, early evaluation on stress concentration and fatigue damage can be realized by measuring initial permeability of the ferromagnetic material. The variation of detection signals with initial permeability is researched via the ANSYS FEM simulation and the tensile testing of 45 steel. The results indicate that the detection signals have a linear relation with initial permeability of the ferromagnetic material. It is seen that initial permeability testing technology can give effective and accurate evaluation of the ferromagnetic material.

Multi Walled Carbon Nanotube

In this study, three various types of fillers; pristine multi-walled carbon nanotube (MWCNT), hydroxyl functionalized multi-walled carbon nanotube (MWCNT-OH) and carboxyl functionalized multi-walled carbon nanotube (MWCNT-COOH) were used to prepare epoxy (EP) composites via ultrasonication and casting techniques. The effect of pristine MWCNT and functionalized MWCNT (MWCNT-OH and MWCNT-COOH) and fillers loading (0-1.0 vol%) on tensile properties of EP composites were investigated and compared. To identify the effectiveness of functional groups on the EP composites, the MWCNT, MWCNT-OH and MWCNT-COOH were compared through tensile testing. The addition of pristine MWCNT decreased the material’s tensile strength and modulus, while the addition of MWCNT-OH decreased the material’s tensile strength. However, among the EP composites, the 0.4 vol% MWCNT-COOH/EP composite exhibited a 12.80% increase in tensile strength (44 MPa). The tensile modulus of 0.4 vol% MWCNT-OH/EP and MWCNT-COOH/EP composites were found to be significantly higher compared to unfilled epoxy which were approximately 15.60% (2376 MPa) and 18.54% (2436 MPa) respectively. In conclusion, the MWCNT-COOH/EP composite showed slight improvement in both the tensile strength and modulus. The effect of functionalized MWCNT was supported by morphological analysis, which demonstrated an improvement in MWCNT-COOH dispersion with slightly fine agglomerates particles at 0.4 vol%.

Polyesteramide (PEA) have good mechanical properties, compositing with multi-walled carbon nanotubes (MWNTs) can further improve the mechanical properties of the polymer. In this paper, PEA/MWNTs were synthesized in-suit using the reinforcement of nanocomposite. SEM and tensile testing were used to characterize the composited polyesteramides. The results show that MWNTs can be uniformly dispersed in the composited polyesteramides, the PEA/MWNTs tensile strength and Elongation at break increased.

Abstract The aim of this study was to estimate the measurement uncertainty for a material produced by additive manufacturing. The material investigated was FullCure 720 photocured resin, which was applied to fabricate tensile specimens with a Connex 350 3D printer based on PolyJet technology. The tensile strength of the specimens established through static tensile testing was used to determine the measurement uncertainty. There is a need for extensive research into the performance of model materials obtained via 3D printing as they have not been studied sufficiently like metal alloys or plastics, the most common structural materials. In this analysis, the measurement uncertainty was estimated using a larger number of samples than usual, i.e., thirty instead of typical ten. The results can be very useful to engineers who design models and finished products using this material. The investigations also show how wide the scatter of results is.
