Recent advances in the use of Polyamide-based materials for the automotive industry

Abstract

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.

Tuning Interfacial Adhesion in Polyester/Polyamide Systems

“…Polyamides (PAs) get employed in many industrial areas, including the textile, automotive, medical, and packaging sectors. PAs possess desirable and distinct properties such as excellent mechanical properties, chemical and heat resistance, self-lubricity, plausible barrier properties, and good processability. − Strong interchain hydrogen bonds formed between neighboring amide groups result in high strength, abrasion resistance, and good toughness. ,,− The properties of PAs are also greatly reliant on the amide linkage and methylene sequence in the polymer chains, which influences the hydrogen bond density. , The broad application of PAs is limited because of rapid crystallization, processing instability, and moisture sensitivity. , However, coupling PA with other polymers can improve PAs’ properties.…”
