Abstract

Bu çalışmada güçlendirilmiş bükme LVL’lerin eğilmede deformasyon miktarı üzerine güçlendirici ve tutkal türünün etkisi incelenmiştir. Çalışma kapsamında ahşap malzeme olarak 2,2mm soyma kavak kaplama, 1,5mm soyma kızılağaç kaplama kullanılmıştır. Güçlendirici olarak cam elyafı ve bazalt kumaş (200g/m²) kullanılmıştır. Alt ve üst yüzeyde kızılağaç kaplaması, orta tabakalarda kavak kaplama kullanılmıştır. Güçlendirici malzeme bükme LVL’nin dışbükey yüzeyine uygulanmıştır. Toplam 7 farklı kombinasyonda sandalye ayak-kolçak formunda bükme LVL üretimleri yapılmıştır. Üretilen LVL’lere eğilme testi, çekme testi ve ANSYS programında eğilme testi yapılmıştır. Test sonuçlarına göre güçlendirici kullanımı ile eğilme deformasyonunda azalma olduğu tespit edilmiştir. En iyi sonucun cam elyafı ve epoksi kullanımı ile sağlandığı belirlenmiştir. Ayrıca ANSYS sonuçları ile gerçek test sonuçlarının benzer olduğu görülmüştür.

Abstract

In this study, the effect of reinforcement type and glue type on the amount of flexural deformation of reinforced bending LVLs was investigated. Within the scope of the study, 2.2mm peeled poplar veneer and 1.5mm peeled alder veneer were used as wood material. Glass fiber and basalt fabric (200g/m²) were used as reinforcement. Alder veneer was used on the lower and upper surfaces, and poplar veneer was used on the middle layers. Reinforcement material was applied to the convex surface of the bending LVL. A total of 7 different combinations of bending LVLs in the form of chair leg-armrest were produced. Flexural test, tensile test and ANSYS analysis were performed on the produced LVLs. According to the test results, it was determined that there was a decrease in flexural deformation with the use of reinforcement. It was determined that the best results were obtained with the use of glass fiber and epoxy. In addition, ANSYS results and real test results were found to be similar.
