“…Based on all these results, replacing Nylon with HDPE reinforced with 40%wt of SBF in spur gears manufacturing can be foreseen, which represents a promising alternative and an interesting subject for future research work. Comparison between mechanical properties of some plastic materials [31,[37][38][39][40][41][42][43][44][45][46][47] and thermoplastic polymers [24,31,39,[48][49][50][51][52][53][54][55] of residual strength versus number of cycles [61]…”

A new natural fiber composite made of high density polyethylene (HDPE) and short birch fibers (SBF) was developed to replace high-performance thermoplastics (Polyamide) commonly used in gears manufacturing.3-point flexural quasi-static tests were achieved on bending specimens to assess mechanical properties.Comparison between these results and those of polyamide (PA) and neat polyethylene has showed that the polyethylene reinforced with 40%wt of SBF presents tensile and flexural mechanical properties that are higher than those of the PA11 or the neat polyethylene. After static characterisation, fatigue tests were performed to determine ε-N curves and the evolution of residual strength. Then, the fatigue behavior of the studied composite has been compared with that of PA66 and of ultra-high molecular weight polyethylene (UHMWPE). It has been noticed that polyethylene reinforced with 40%wt of SBF presents a high cycle fatigue strength (HCFS) that is more important than that of PA66 and UHMWPE. Consequently, the studied composite represents a good alternative to replace Nylon in spur gears manufacturing.

“…In comparison to unmodified MgAl-LDH, the FTIR spectrum of the organomodified MgAl-LDH reveals the presence of DBS anion in the filler. The characteristic vibration bands were detected for SO 3 − stretchings (symmetric stretching at 1038 cm −1 and asymmetric at 1183 cm −1 ), the benzene group (C-C stretching at 1460 cm −1 , C-H in plane bending at 1004 and 1140 cm −1 ) and alkyl group (asymmetric stretching of CH 3 and CH 2 at 2963 and 2925 cm −1 , respectively; symmetric stretching of CH 3 and CH 2 at 2872 and 2851 cm −1 , respectively). The bands recorded below 800 cm −1 , especially the sharp and strong characteristic band around 452 cm −1 appear due to the vibration of metal-oxygen bond in the brucite-like lattice.…”

“…Introducing flame retardant additives into matrix polymer, therefore, is an essential step and phosphorous or metal oxide containing flame retardants are mostly employed in this manner to maintain flame retardancy. Besides microscale conventional flame retardant technologies, nanocomposites seem to be a promising alternative and, most of the ongoing investigations focus on a sub-class of nanocomposites, polymer/layered silicate nanocomposites [1][2][3]. However, in the recent years, polymer/layered double hydroxide (LDH) nanocomposites have drawn an enormous attention among polymer-clay nanocomposites [4][5][6].…”

The localization of multiwall carbon nanotubes (MWCNTs) in the immiscible blends of ethylene-1-octene copolymer (EOC) and cyclic olefin copolymer (COC) with the seaisland morphology and electrical conductivity of resulting nanocomposites were investigated. Depending on the feeding orders, as the MWCNTs were located in the COC droplet, the electrical conductivity was obtained as high as 5.71 × 10 −7 S/cm, while the MWCNTs were located in EOC/COC interface, the electrical conductivity increased significantly up to 1.72 × 10 −2 S/cm. The improved electrical conductivity in EOE/COC/MWCNTs nanocomposite is attributed to the interfacial localization of MWCNTs which is resulted from thermodynamic affinity of MWCNTs to COC, as well as an interconnected structure via deformed and swelled COC droplets. Thermodynamic affinity of MWCNTs to COC and established interconnected structure are confirmed by rheological characterization, microscopic observations, dynamic mechanical analysis, and electrical conductivity measurements. Therefore, as a result of selective localization of MWCNTs and well-designed phase morphology, lower rheological and especially electrical percolation thresholds could be obtained in the ternary nanocomposites compared to the binary systems.
