“…Due to its relatively long hydrocarbon chain, the density of PA12 is only 1.01 g/cm 3 . Based on the mentioned characteristics, PA12 and its copolymers are used in many industries, especially in sports goods [ 19 ] (e.g., soccer shoes [ 20 ]), aerospace [ 21 , 22 , 23 ], automotives [ 24 ] (e.g., fuel tubes [ 25 ] and under-the-hood [ 26 ]), food (e.g., packaging [ 27 , 28 , 29 ]), health (e.g., femoral stems [ 30 ], hip implants [ 31 ] and biomedical [ 32 ]) and the oil and gas (e.g., oil and gas pipelines [ 33 , 34 ] and crude oil transport [ 35 ]) industry.…”

Chemically speaking, polyamide 11 (PA11) and polyamide 12 (PA12) have a similar backbone, differing only in one carbon. From an origin point of view, PA11 is considered a bioplastic polyamide composed from renewable resources, compared to oil-based PA12. Each of them has a number of advantages over the other, which makes their selection a challenging issue. Depending on the target application, diverse assessments and comparisons are needed to fulfill this mission. The current study addresses this research gap to characterize and compare PA11 and PA12 manufactured by the hot press technique in terms of their mechanical, thermal and durability properties for the first time, demonstrating their potential for future works as matrices in composite materials. In this regard, different characterization techniques are applied to the hot-pressed polymer sheets, including X-ray diffraction (XRD), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The mechanical performance of the PA11 and PA12 sheets is compared based on tensile tests and shore hardness measurement. The durability behavior of these two polyamides is evaluated in water and relative humidity conditions at different aging times. The experimental results show the ductile behavior of PA12 with respect to the quasi-brittle PA11. Both have a relatively small water and moisture gain: 1.5 wt% and 0.8 wt%, respectively. The higher crystallinity of PA12 (2.1 times more than PA11) with γ-phase is one of the leading parameters to achieve better mechanical and durability properties. The FTIR spectra displayed slight acid hydrolysis. Accordingly, absorbed water or moisture does not cause plasticization; thus, neither hardness nor dimension changes.

“…Composites constitute the most important class of materials next to steels in industrial applications [1]. Other applications include aerospace [2], automotive industry [3], sporting goods [4,5], marine structures [6,7], food packaging [8], home appliances, medical applications [9] and construction industry [10]. In such applications it is required to know the mechanical and tribological properties of polymer composites.…”

Polymer matrix composites (PMCs) are extensively known for their higher strength and stiffness at lower weight compared to traditional materials. They are extensively used in numerous engineering applications. Utilization of these materials had been extended to novel areas where it is essential to study their tribological performance. Several research works reported the tribological performance of polymer composites. The aim of the review is to provide broad information on erosion behaviour of polymeric composites. Attention is paid towards the effect of test parameters i.e. impact velocity, erodent characteristics, impingement angle on the erosion wear rate and their failure mechanisms were discussed. Inclusion of various fillers in to polymeric composites enriched the erosion resistance property that attracted the researchers to find out their application. However limited literature were available on the erosion behaviour of particle filled composites. Hence, another objective is to review available literature on the erosion response of filled composites.

“…Thermoplastic matrix composites have been studied for many years and characterized by their potential advantages such as lower storage costs, re-processability, high recyclability, and high damage tolerance compared to thermoset matrix composites. [1][2][3][4][5][6] In particular, thermoplastic composites can be joined by welding. Such composite welding technologies have been studied to achieve cost-effectiveness in the assembly of thermoplastic composites by reducing assembly time and the number of fasteners required.…”

This paper presents details of the mechanical properties related to the static and fatigue strength of carbon fiber reinforced polyetherketoneketone (CF/PEKK) thermoplastic induction-welded composite joints. To better understand the process parameters, the finite element modeling (FEM) of the heat distribution was analyzed based on the generator power, coil coupling distance, coil moving speed, frequency, compaction force, and coil geometry while maintaining the optimal coil speed. The temperature behavior calculated using the simulation model exhibited good agreement with experimental results. A microscopic inspection, non-destructive test (NDT) was conducted to check the morphology characteristics of the welded joints. To check the mechanical performance of the induction-welded specimens, single-lap shear strength (SLSS) tests under static and cyclical fatigue loading conditions were conducted to check the weld qualities from a practical perspective. The mechanical testing results indicated that the static and cyclical fatigue specimens were dominated by a cohesive failure mode with a light fiber tear (LFT). These results suggested that using the optimal process parameters based on multi-physics FEM simulation could potentially improve mechanical performance.
