Abstract

This study was carried out to determine the changes in air-dry density and fiber-parallel compressive strength of basalt fiber-reinforced polymer (BFRP) woven fabrics (WF) and plaster mesh (PSM) reinforced sessile oak laminated timber. One component polyurethane (PUR) glue was used as the adhesive. The BFRPWF abd PSM were added as a reinforcement layer between wood veneers to improve properties of laminated composite material. The BFRPWF and PSM were tested in three different locations non-reinforced laminated oak lumber (LOL), reinforced laminated oak lumber with the BFRPWF (LOL- BFRPWF), and reinforced laminated oak lumber with the PSM (LOL-PSM). Tests were performed on the LOL, LOL- BFRPWF, and LOL-PSM to investigate their air-dry density (δl2), and compression strength (σb). The test results showed that the reinforcement process increased both δl2 and σb parallel to the grains. The LOL-BFRPWF samples give better results than PSM and control samples. Accordingly, the samples of LOL-BFRPWF and LOL-PSM samples have the potential to serve as viable options for both furniture and building materials.

BAZALT KUMAŞ VE PLASTER NET İLE GÜÇLENDİRİLMİŞ LAMİNE MEŞE KERESTENİN HAVA KURUSU YOĞUNLUK VE LİFLERE PARALEL BASINÇ DİRENCİNİN BELİRLENMESİ

Abstract

Bu çalışma, bazalt kumaş (BFRP) ve plaster mesh (PSM) güçlendirilmiş sapsız meşe lamine kerestenin hava kurusu yoğunluk ve liflere paralel basınç direncindeki değişimlerin belirlenmesi amacıyla yapılmıştır. Yapıştırıcı olarak tek komponentli poliüretan (PUR) tutkalı kullanılmıştır. BFRPWF ve PSM, lamine kompozit malzemenin mekanik özelliklerini geliştirmek için ahşap kaplamalar arasına takviye katmanı olarak eklenmiştir. BFRPWF ve PSM, takviyesiz lamine meşe kereste (LOL), BFRPWF (LOL-BFRPWF) ile güçlendirilmiş lamine meşe kereste ve PSM (LOL-PSM) ile güçlendirilmiş lamine meşe kereste üç farklı lokasyonda test yapılmıştır. Hava kuru yoğunluk (δl2) ve liflere paralel basınç direncini (σb) araştırmak için LOL, LOL-BFRPWF ve LOL-PSM üzerinde testler yapılmıştır. Test sonuçları, güçlendirme işleminin hem δl2 hem de σb'yi arttırdığı göstermiştir. LOL-BFRPWF örnekleri PSM ve kontrol örneklerinden daha iyi sonuçlar elde edilmiştir. Buna göre LOL-BFRPWF ve LOL-PSM örneklerinin örnekleri, hem mobilya hem de yapı malzemeleri için uygun seçenekler olarak hizmet etme potansiyeline sahip olduğu söylenebilir.
