Abstract

Çalışmanın amacı: Bu çalışma kısa cam lif güçlendirmesi ile odun plastik kompozitlerinin (OPK) bazı fiziksel, mekanik özelliklerini ve yanma direncinin arttırılmasını amaçlamıştır.
Materyal ve Yöntem:OPK’lar farklı oranlarda kısa cam lifleri ile güçlendirilmiştir. Güçlendirmenin fiziksel özellikler olarak su alma, kalınlığa şişme, mekanik özellikler olarak eğilme direnci, elastikiyet modülü ve çekme direncine olan etkisi belirlenmiştir. Yangın direnci performansı ayrıca limit oksijen indeksi (LOI) testi ile değerlendirilmiştir.
Sonuçlar: Güçlendirme fiziksel özellikleri iyileştirmiştir. Su alma ve kalınlığa şişme değerleri artan cam lif içeriği ile azalmıştır. Eğilme direnci %28'e kadar yükselirken, çekme mukavemeti %24’e kadar artmıştır. Elastikiyet modülünde önemli bir iyileşme olmuştur (~%122). Cam elyaf takviyesi ayrıca OPK’ların yangın performansını da iyileştirmiştir.
Önemli vurgular: OPK’lar için sentetik elyaf takviyesi ile daha yüksek özellikler elde edilebilir

Effect of Short Glass Fiber Reinforcement on Physical, Mechanical Properties and Fire Performance of Wood Plastic Composites

Abstract

Aim of study: This study aimed to improve some physical, mechanical properties, and fire resistance of wood-plastic composites (WPCs) with short glass fiber reinforcement (SGFR).
Materials and Methods: The WPCs were reinforced with different ratios of short glass fiber (SGF). The effect of reinforcement on the water absorption (WA), thickness swelling (TS) as physical properties, flexural strength, modulus of elasticity, and tensile strength as mechanical properties were determined. The fire resistance performance was also evaluated by the limit oxygen index (LOI) test.
Main results: The reinforcement improved the physical properties. The WA and TS values decreased with increasing glass fiber content. Flexural strength increased up to 28%, while 24% for tensile strength. There was a substantial enhancement in the modulus of elasticity (up to 122%). The glass fiber reinforcement also improved the fire performance of WPCs.
Highlights: The higher properties could be obtained by synthetic fiber reinforcement for WPCs.
