Polyamide 12/Antimony Trioxide/Sepiolite or Boron Composites: Mechanical Properties and Flame Retardancy

Abstract

This study reports on the mechanical and flame-retardancy properties of polyamide 12 (PA 12) based composites reinforced with antimony trioxide, sepiolite, or boron powders. These composites were fabricated by the twin-screw extruder and hot-press techniques. The microstructural characteristics and flame-retardancy of the PA 12-based composite samples were obtained by using a scanning electron microscope, a vertical UL-94 burning, and limiting oxygen index tests. The Shore-D hardness, Charpy impact, and tensile tests were conducted to reveal the mechanical performance of composites. The PA 12/antimony trioxide/sepiolite sample presented the best mechanical performance. The additions of antimony trioxide/boron into the PA 12 matrix gave the best contribution to the flame-retardancy.

Studying the Fabrication and Characterization of Polymer Composites Reinforced with Waste Eggshell Powder

“…Among thermoplastic polymer matrices, polyamide 12 (PA) is one of the most important applied matrices for polymer composites. Additionally, this material is a semicrystalline thermoplastic polymer and is considered a crucial material as a result of its economical production costs and its excellent chemical and thermal characteristics [2,3]. Moreover, the PA12 polymer matrix presents excellent properties, such as low density, superior dimensional stability, and relatively higher flexural and tensile strengths [4,5].…”

“…Moreover, the PA12 polymer matrix presents excellent properties, such as low density, superior dimensional stability, and relatively higher flexural and tensile strengths [4,5]. Furthermore, PA polymer composites have the ability to disseminate their applications with developed flame-retardant characteristics [2,6]. Therefore, thermoplastic PA has been extensively used in different engineering applications, for example, in automotive, aircraft, aerospace, and in other industrial applications [3,7].…”
