“…The samples aged in the humidity chamber also showed a lower reduction in mechanical performance when exposed to Grip-It™ compared to the samples aged at the same temperature at ambient humidity. Other researchers have reported a reduction in the stiffness of ABS when aged in a humid environment [18,19]. It is likely that the moisture is absorbed into the acrylonitrile component of ABS [20][21][22] and acts as a plasticiser protecting against ESC to some extent.…”

“…No significance difference was found between the spectra of untreated samples and those exposed to MEK or IPA solution. An increase in peak height at 1600-1700 cm -1 was observed which may be attributed to formation of ketonic group by oxidation reactions [18,32]. This peak was also found to increase with the addition of EVA content in LDPE which may suggest that these samples are less protected to oxidation.…”

In extension with the previous work, recycling of the waste polyolefins by dissolution/ reprecipitation method, has been investigated. The goal of study was to explore the influence of organo-modified/ unmodified sodium montmorillonite clays, on the behaviours of waste polyolefins inclusive low density polyethylene (LDPE) and high density polyethylene (HDPE). 1-5 wt % of unmodified (MMT) and Organo-modified clay (OMMT) were added to the polyolefins, to prepare polyolefin-clay nanocomposites by melt intercalation method. X-ray diffraction (XRD) and Field Emission Scanning Electron Microscope (FESEM) were used to estimate the dispersion of clay in the polymer matrices and the morphology of nanocomposites. Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) were used to analyse the change in the thermic properties of the waste polyolefins nanocomposites. The XRD and FESEM results showed an intercalated structure in the HDPE and LDPE with Organo-clay nanocomposites, whereas no exfoliation was observed with unmodified clay in both waste HDPE and LDPE, respectively. DSC and TGA, showed an improved thermal behaviours in the HDPE/Organo-clay nanocomposites (3 wt%) clay loading. Melting temperature and crystallization percentage were observed to increase in 1, 2, and 3 wt% loadings. In waste LDPE/ clay nanocomposites, no improvement was established in the thermal stability.

“…Carbon-fiber-reinforced thermoplastics (CFRTP) have received much attention recently due to their high strength/elasticity-to-weight ratios, as well as high damping capability compared to metallic materials (Refs. [1][2][3][4][5]. To expand the application of CFRTP, joining of CFRTP to form large and complex engineering structures is inevitable.…”

Influence of Horn Misalignment on Weld Quality in Ultrasonic Welding of Carbon Fiber/Polyamide 66 Composite

In this study, the influence of horn axial misalignment on the quality of ultrasonic welded lapped carbon-fiber/polyamide 66 composite (C f /PA 66) was investigated. An analytical model was derived to estimate the energy absorption in the welding zone of the thermoplastic material and, consequently, permit the estimation of weld size. Using this model, the effect of the horn misalignment on the weld size was examined and validated. Results of the modeling and experiments showed the horn misaligned by more than 4 deg resulted in a significant decrease in weld area, weld strength, and cosmetic quality, which was mainly attributed to the energy deviation at the faying surfaces. This study provides a good understanding of the influence of horn misalignment on the quasi-static characteristics of the ultrasonic welded carbon-fiber-reinforced polyamide 66 composite.
