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.

Özet

Bu çalışmada, antimon trioksit, sepiolit veya bor tozları eklenerek üretilen poliamid 12 (PA 12) esaslı kompozitlerin mekanik ve alev geciktirici özelliklerini rapor edilmiştir. Bu kompozitler, çift vidalı ekstrüder ve sıcak presleme teknikleri ile hazırlanmıştır. PA 12 esaslı kompozitlerin mikroyapısal ve alev geciktirici özellikleri, taramalı elektron mikroskobu, dikey UL-94 yanma testi ve sınırlayıcı oksijen indeksi (LOI) testleri ile karakterize edilmiştir. Polimer kompozitlerin mekanik performansı, Shore-D sertlik, Charpy darbe dayanımı, ve çekme (dayanımı ve kopma uzaması) testleri ile ortaya çıkarılmıştır. En iyi mekanik performansın antimon oksit/sepiyolit katkılı PA 12 numunesi göstermiştir. Antimon oksit/bor katkısı yapılmış PA 12 bazlı kompozit numunenin en iyi alev geciktirici performansı göstermiştir.
