Özet:

 Sandwich panels are preferred in many sectors, such as automotive, construction, and aircraft. In addition, it is used in many areas as an isolation material. We aim to produce boards that are both lightweight and have the desired durability in their field of use, made from polyurethane, which has low heat conduction, and wood material with high resistance properties, especially for use in isolation. In our study, poplar panels were used as coating materials and polyurethane foam was used as foam. Sandwich panels were prepared using 1 cm, 3 cm, and 5 cm thick polyurethane foam and 5 mm poplar panels. These panels mechanical properties bending and compressive strength, thermal conductivity, and physical properties were examined. Its ability to absorb water and swell to its thickness was investigated among its physical properties. The test results showed that the sandwich panels prepared with 5 cm thick polyurethane foam had lower water absorption and swelling rates, so their water resistance was better. The sandwich panel with the highest thermal conductivity coefficient is prepared with 5 cm thick polyurethane foam. The panel with the lowest heat conduction coefficient is prepared with 3 cm thick polyurethane foam. Accordingly, 3 cm thick polyurethane foam panels have the best insulation. It was concluded panels prepared with 1 cm thick polyurethane foam had the best mechanical values.

 Sandviç paneller günümüzde otomotiv, inşaat, uçak gibi pek çok sektörde tercih edilen bir malzemedir. Bunun yanı sıra izolasyon malzemesi olarak pek çok alanda kullanılmaktadır. Çalışmamızda özellikle izolasyon alanında kullanılmak amacıyla ısı iletimi düşük olan poliüretan ve yüksek direnç özelliklerine sahip ahşap materyalden hem hafif hem de kullanım alanında istenen sağlamlığa sahip levhalar üretmektir. Çalışmamızda kaplama malzemesi olarak kavak paneller, köpük olarak poliüretan köpük kullanılmıştır. 1 cm, 3 cm ve 5 cm kalınlıkta poliüretan köpüğe 5 mm kavak panel kaplama kullanılarak sandviç paneller hazırlanmıştır. Bu panellerin bazı mekanik özellikleri eğilme direnci ve basınç direnci, ısı iletkenlikleri ve fiziksel özellikleri incelenmiştir. Fiziksel özelliklerden su alma ve kalınlığına şişme özelliğine bakılmıştır. Test sonuçlarına göre 5 cm kalınlıkta poliüretan köpükle hazırlanan sandviç panellerin su alma ve kalınlığına şişme oranlarının daha düşük olduğu yani suya dayanımlarının daha iyi olduğu görülmüştür. Isı iletim katsayısı en yüksek sandviç panel 5 cm kalınlıkta poliüretan köpükle hazırlanan olup en düşük ısı iletim katsayısına sahip panel ise 3 cm kalınlıkta poliüretan köpükle hazırlanan panellerdir. Buna göre yalıtkanlığı en iyi olan sandviç paneller 3 cm kalınlıkta poliüretan köpükle hazırlanmış panellerdir. Mekanik test sonuçlarına bakıldığında ise mekanik olarak en iyi değerlerin genellikle 1 cm kalınlıkta poliüretan köpükle hazırlanmış panellerde olduğu sonucuna ulaşılmıştır.
