“…Wei et al [39] researched the aging properties of PA12 exposed to biodiesel at high temperatures, citing that PA6 and PA12 can be used in vehicle fuel systems because of their excellent balance of mechanical properties and barriers properties against hydrocarbons. Hıdıroğlu et al [40] studied the reduction of daily rate hydrocarbons evaporation from PA12 automobile fuel transfer pipes prepared by radiation crosslinking. In Table 2 is presented a summary of the important uses of polyamides in automotive industry.…”

“…Hıdıroğlu et al [40] prepared oil and fuel transfer ducts through direct extrusion in a layer extruder, where there are different dosing zones to insert different phases into the final product. According to the authors, it was proven that the degree of crosslink is directly linked to the final properties of the product, such as mechanical properties and permeability to gases.…”

Polyamide (PA) is a well-known and researched thermoplastic due to its excellent mechanical and physical properties, making it developed in the automotive sector, suitable for lighter vehicles, and, consequently, lower fuel consumption. This review manuscript presents the applications of PA-based materials in the manufacture of vehicle parts, with a description of their processing, a discussion about their thermal properties and the crystallization of polymer structure, the challenges of machining PA-based composite materials, and the feasibility of recyclability. This work aims to revise literature about the use of polyamide 6 (PA6), polyamide 66 (PA66), and polyamide 12 (PA12) and their composites reinforced with fiberglass (FG) and carbon fiber (CF) focused on the potential that these materials have as alternative materials for the automotive industry.

“…The molecular structure of EVOH, such as molecular weight, content, and distribution of comonomers, is determined by the control of polymerization conditions. Different molecular structures give EVOH different processing properties, barrier properties, and thermal stability; meanwhile, we can obtain different types of EVOH widely used in various fields, such as film, pipe, and sheet products through thermoplastic processing that are used in food packaging, cosmetics, automobile fuel tanks, and barrier pipes 4–8 …”

[4][5][6][7][8] Unfortunately, EVOH products still tend to yellowing and form fisheye or hard spots during processing, 9,10 which cannot be ignored. As well known in EVOH, the insertion of ethylene sequences into vinyl alcohol segments reduces the barrier property to a certain extent and disrupts the compact packing of vinyl alcohol segments.…”

To study the effect of molecular structure on ethylene‐vinyl alcohol copolymer (EVOH) thermal stability during processing, EVOH samples with different molecular weights and comonomer distributions were prepared by solubility fractionation from two different commercial materials, and then, the structure features of samples were characterized by 1H‐NMR, viscometry, differential scanning calorimetry, and, especially, successive self‐nucleation and annealing. Their thermal stabilities were further analyzed by isothermal oxygen treatment and thermogravimetry. Attenuated total internal reflectance Fourier transform infrared spectroscopy and UV were used to obverse the structural changes in samples (the formation of chromogenic groups: CO and CC). According to the results of isothermal oxygen treatment at 200°C, at the same ethylene content, low‐molecular‐weight samples have worse thermal stability, which were extremely easy to yellowing and form insoluble gel. To investigate the structure differences between the low‐molecular‐weight samples, it was found that long vinyl alcohol segments may not worsen the thermal stability in the conditions of the same ethylene content. But samples with a uniform distribution of ethylene segments and a certain length of ethylene segments will have better thermal stability, which makes it more difficult to form carbonyl even diketene conjugation structure.
