ABSTRACT To develop continuous fibre compos laminates and fabrics in the aeronautics and aerospace industry, a thorough understanding of the behaviour of these materials under various loading conditions is required. The purpose of this work aims to assess the failure of different composite materials subjected to a bending load, using the progressive damage approach. Puck’s failure criteria and gradual degradation model have been used to simulate the initial and the successive damage, respectively. A user-defined material (UMAT) subroutine has been developed and implemented through finite element software Abaqus. Moreover, the effect of geometrical parameters is performed and identified by the experimental protocol. The predicted results obtained by this numerical modelling show a good correlation with the findings of the experimental test.

ABSTRACT In this study, the single-walled carbon nanotube (p-SWCNTs) and poly (methyl methacrylate) (PMMA) polymer nanocomposites were prepared by solution casting method. The effects of functionalization and sodium dodecyl sulfate (SDS) on the thermal properties of PMMA/p-SWCNT nanocomposites were investigated. Samples were characterised using BET, FTIR-ATR, SEM, DTA/TG, DSC, TEM and AFM. Morphological analyses showed that changes in the structure of SWCNTs with modification occurred and CNTs were tubular structure, homogeneously dispersed and nano-sized. Functionalised SWCNTs increased the first mass loss (Tmax1), the second mass loss (Tmax2) and glass transition temperatures (Tg) of PMMA. SDS assisted both better dispersion of CNTs and interaction between PMMA and CNTs. While PMMA/p-SWCNT-OH (0.1 wt.%) had the highest thermal stability in SDS-free medium, PMMA/SDS/p-SWCNT-O-APTS (0.1 wt.%) had the highest thermal stability in SDS medium. The maximum increases at Tmax1 and Tmax2 temperatures of nanocomposites were calculated as 49 and 13°C for PMMA/SDS/p-SWCNT-O-APTS (0.1 wt.%), respectively.

ABSTRACT As technology advances and human population grows, we must meet our diverse needs while minimising harm to the environment. One solution is to prioritise recycling and using second-hand consumer goods. In this study, PET flakes were depolymerised by glycolysis using different molar ratios of glycol such as propylene glycol(PG), triethylene glycol(TEG) and polyethylene glycol(PEG 400) in the presence of two different catalysts: zinc acetate- zinc sulphate. As a result, glycated products (polyols-PO) were obtained. The obtained polyols were then used to synthesise polyurethane films (PU) via acetone process. The thermal and chemical characterisations of the polyurethane films (PU) were analysed. In similar studies, zinc acetate was used as a transesterification catalyst for the glycolysis process. In this study, the same process was carried out using zinc sulphate and zinc acetate. Zinc sulphate was found to be a cheaper and eco-friendlier catalyst alternative to zinc acetate for the glycolysis process.

ABSTRACT Optimal formulation of wood-plastic composites (WPCs) from recycled polypropylene (rPP) and rubberwood flour (RWF) was determined. Mechanical properties and long-term creep behaviour of rPP and WPCs were investigated. This study revealed that an increasing of rubberwood flour content clearly increases the flexural, compressive, and tensile values. The modulus of composite samples linearly increased with an increasing amount of RWF. The creep behaviour test with load levels at 20, 30, and 40% of the ultimate flexural strength were conducted for 1000 h. The deflection of the composites at the same load levels of rPP gave the higher creep behaviour (2.45, 4.65, and 6.68 mm) than that of WPCs (1.53, 2.41, and 3.37 mm), respectively. Six-element for determining Burger model parameters was well fitted with the long-term creep of WPCs, this deflection result was compared to four-element Burger and Power law models. Finally, the master curve could predict lifetime of composite materials.

ABSTRACT Developing thermally conductive rubber nanocomposites for heat management is a difficult task for many applications, including tires. Even though rubber materials generally have poor thermal conductivity, the addition of various conductive fillers is required to prevent heat accumulation. However, high filler loading has a significant effect on the mechanical properties of the final product. In addition to the role of filler loading, structure, and morphology, various types of functionalization are required to improve the incorporation of the fillers in the rubber matrix. The main objective of this review is to summarise recent investigations on the thermal and mechanical properties of rubber nanocomposites filled with carbon-based particles such as carbon black, carbon nanotubes, and graphene derivatives.

ABSTRACT In the present study, we introduce the first study for investigating the effect of polyethylene glycol (PEG) on the electrochemical performance of the PTy electroactive film. In this work, we applied PEG to improve electrochemical performance of PTy electroactive film. The electrochemical properties of the prepared electrodes were investigated by means of various electrochemical methods including electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and consecutive charge/discharge. The developed electrode in this study exhibits a specific capacity of 4200 mF.cm−2 at 5 mA.cm−2 current density while retaining 90% of the initial capacitance after 3000 cycles. Our results provide an improved conductive polymer composite film with high active surface area, ease of synthesis and high cycling stability for supercapacitors (SCs) in aqueous electrolytes.

ABSTRACT This study investigated the effect of a functionally graded negative stiffness (FGNS) honeycomb made from polyamide 12 (PA12) on increasing energy absorption. In addition, the viscoelastic model of PA12 was implemented in the finite element (FE) model to demonstrate the recoverability of these structures. First, a quasi-static compression test was performed on constant thickness negative stiffness (CTNS) honeycomb and FGNS honeycomb. Then, these two structures’ FE models were simulated. The stress relaxation test was utilised to derive Prony series coefficients for PA12 viscoelastic properties. The results of viscoelastic simulation for CTNS and FGNS honeycombs were then compared with experimental results. The comparison demonstrated a good agreement in both the loading and unloading stages. Furthermore, the critical parameters for evaluating the structural energy absorption of the FGNS honeycomb and the conventional ones were used in this study. According to the results, the FGNS honeycomb outperformed the CTNS experimentally and numerically.

ABSTRACT The purpose of the present work is to assess the effectiveness of low-cost and environmental friendly chemical modification of jute fibres based on the usage of sodium hydroxide (AT), sodium carbonate (ST) and sodium hydrogen carbonate (SHT) on the morphological, water absorption, mechanical and tribological characteristics of jute fibre-reinforced epoxy composites (JFREC). Mechanical properties like tensile strength, tensile modulus and impact strength showed appreciable improvement for the AT JFREC (38.08%, 30.56% and 31.66%), ST JFREC (70.03%, 33.06% and 41.30%) and SHT JFREC (24.69%, 8.88% and 22.61%) when compared to untreated JFREC. The experimental results also confirmed that the improved fibre-matrix adhesion, attained by chemical modification, increased the water absorption resistance and the tribological properties of chemically modified JFREC. Improved mechanical and tribological properties attained by the chemically modified JFREC can be found as a potential application in automotive and packaging industries.

ABSTRACT In this study, E-glass fibre-reinforced polypropylene and epoxy matrix composites were produced in different thicknesses and subjected to low-velocity impact tests with 30 joules of energy. The tests yielded force, displacement and energy data, which were used to analyse the effects of thickness variation on impact performance in composite plates with different matrix structures. The results showed that thickness variation creates different impact responses in composites with different matrix materials.

ABSTRACT The interfacial properties of carbon fibre (CF) reinforced epoxy resin composites are the key factors affecting the mechanical properties of the materials. To improve the interfacial adhesion between CF and epoxy resin, an effective CF surface modification method is proposed in this paper. The surface of graphene oxide (GO) was functionalised with 3-aminopropyltriethoxysilane (APTES), and then the functionalised graphene oxide (FGO) was grafted on the surface of CF. The surface roughness of modified CF was significantly improved by the SEM experiment. The effectiveness of grafting was verified by FTIR and XPS, and the chemical functional groups on the surface of modified CF were increased. The microstructure of the failure interface of the composites was observed, the modification did not reduce the tensile strength of CF, and the interlaminar shear strength (ILSS) of modified CF/ epoxy resin composite was increased by 39.91%. It was found that the CF modified by FGO was beneficial to the improvement of the interface properties of CF/epoxy resin composite. This has positive academic significance for improving the interfacial and mechanical properties of CF composites.
