Abstract

Background and aims This study aims to investigate the role of reinforcement type in determining the sound absorption performance of wood-based sandwich panels (WBPS) reinforced with basalt fiber fabric, glass fiber fabric, and jute fabric, using a single-component polyurethane adhesive (PUR-D4). Methods As wood-based panels, 4 mm thick beech plywood and 9 mm thick oriented strand board (OSB-2 class) were used, and a single-component polyurethane adhesive (PUR-D4) was used as adhesive. Basalt fiber fabric, glass fiber fabric, and jute fabric were used as reinforcement layers between the wood-based panels. Test samples of wood-based sandwich panels reinforced with basalt fiber fabric, glass fiber fabric, and jute fabric, and unreinforced wood-based sandwich panels, were tested at four different locations. Results According to the test results, the highest air-dry density (δ₁₂) value was obtained as 740 kg/m³ in WBSP reinforced with glass fiber fabric, while the lowest δ₁₂ value was determined as 687 kg/m³ in unreinforced samples. The highest sound absorption coefficient (SAC) was measured as α = 0.22 in WBSP reinforced with jute fabric, while the lowest SAC value was determined as α = 0.16 in the glass fiber reinforced sample. Similarly, in terms of frequency, the highest SAC value was 1000 Hz (α = 0.35), while the lowest SAC values were measured at 2000 Hz, 2200 Hz, and 2400 Hz (α = 0.12). Conclusion The results suggest that reinforced wood-based sandwich panels offer an effective combination of sound absorption efficiency and material sustainability, making them promising candidates for eco-friendly acoustic panel applications in building and interior environments.

Özet

Giriş ve Hedefler Bu çalışma, poliüretan esaslı bir yapıştırıcı (PUR-D4) kullanılarak bazalt lifli kumaş, cam lifli kumaş ve jüt kumaş ile takviye edilmiş ahşap esaslı sandviç panellerin (WBPS) ses emilim performansını belirlemede takviye türünün rolünü araştırmayı amaçlamaktadır. Yöntemler Ahşap esaslı levha olarak, 4 mm kalınlıkta kayın kontrplak ve 9 mm kalınlıkta yönlendirilmiş şerit levha (OSB-2 sınıf ) ayrıca yapıştırıcı olarak ise tek komponentli poliüretan (PUR-D4) tutkalı kullanılmıştır. Ahşap esaslı levhaların arasına takviye katmanı olarak basalt elyaf kumaş, cam elyaf ve jüt kumaş kullanılmıştır. Basalt elyaf kumaş, cam elyaf kumaş ve jüte kumaş takviye edilmiş ve takviyesiz ahşap esaslı sandviç panellerin deney numuneleri dört farklı lokasyonda test edilmiştir. Bulgular Test sonuçlarına göre, en yüksek hava kurusu yoğunluk değeri (δ₁₂), cam elyaf kumaş ile güçlendirilmiş WBSP’de 740 kg/m³ olarak elde edilirken, en düşük δ₁₂ değeri takviyesiz numunelerde 687 kg/m³ olarak belirlenmiştir. En yüksek ses yutum katsayısı (SAC), jute kumaş ile takviye edilmiş WBSP’de α = 0,22 olarak ölçülmüş, en düşük SAC değeri ise cam elyaf kumaş ile güçlendirilmiş α = 0,16 olarak tespit edilmiştir. Benzer şekilde, frekans değeri bakımından en yüksek SAC değeri 1000 Hz α = 0.35 iken, en düşük SAC değeri ise 2000 Hz, 2200 Hz ve 2400 Hz (α = 0,12) olarak ölçülmüştür. Sonuçlar Güçlendirilmiş ahşap esaslı sandviç panellerin ses emilim verimliliği ve malzeme sürdürülebilirliğinin etkili bir kombinasyonunu sunduğunu ve bu nedenle bina ve iç mekân ortamlarında çevre dostu akustik panel uygulamaları için umut vadeden adaylar olduğunu göstermektedir.
