Abstract

In this study, the effects of expendable graphite (GG) and organoclay (OK), which are used for creating synergistic effect, on the flame retardant, thermal and mechanical properties of the ammonium polyphosphate (APP) containing polypropylene (PP) / carbon fiber (KF) composites have been investigated. The thermal and flammability properties of the composites are investigated by thermogravimetric analysis (TGA), limiting oxygen index (LOI) and UL-94 tests. The mechanical properties are examined by making dynamic mechanic analysis (DMA) and tensile tests. The test results show that the use of 1 wt% GG improves the flammability properties via the increased char formation. The mechanical properties are improved with the addition of 1 and 3 wt % OK whereas no improvement in flammability properties is observed.

Özet

Bu çalışmada; sinerjik etki yaratmak amacıyla kullanılan genişleyen grafit (GG) ve organokilin (OK) kabaran amonyum polifosfat (APP) içeren polipropilen (PP)/karbon elyaf (KF) kompozitlerin güç tutuşurluk, ısıl ve mekanik özellikleri üzerine etkileri incelenmiştir. Üretilen kompozitlerin ısıl ve güç tutuşurluk özellikleri termogravimetrik analiz (TGA), sınırlayıcı oksijen indeksi (LOI) ve UL-94 testleriyle, mekanik özellikleri ise dinamik mekanik analiz (DMA) ve çekme testleriyle incelenmiştir. Test sonuçları, ağırlıkça %1 GG kullanımının kül oluşumunu artırarak güç tutuşurluk özelliklerini iyileştirdiğini göstermiştir. %1 ve 3 oranında OK ilavesinin ise kompozitlerin mekanik özelliklerini iyileştirdiği fakat güç tutuşurluk özelliklerini iyileştirmeye katkı sağlamadığı gözlemlenmiştir.
