Bu deneyim isteği aynı zamanda bu kültürel mirasın korunma ihtiyacını da ön plana çıkarır. Safranbolu kültür turizmi bağlamında; tamamı sit alanı olarak kabul edilmiş eski çarşı bölgesi ve koruma altına alınan tarihi evleriyle tanınmaktadır. Bu nedenle, bölge hem yerli hem de yabancı birçok turist tarafından ziyaret edilmektedir. Safranbolu gezisi sırasında bazı ziyaretçiler, tarihi atmosferi, özgün dokuyu ve geçmişi deneyimleme amacıyla tarihi çevrede bulunan otellerde konaklamayı tercih etmektedirler. Bu talep doğrultusunda bölgede bulunan bazı konaklar otellere dönüştürülmüştür. Bu dönüşüm, tarihi çevrede bulunan otellerin hem orijinal dokuyu koruma hem de günümüz konfor beklentilerini karşılama zorunluluğunu ortaya çıkarmaktadır. Bu çalışmada, iç mekan ve bileşenleri bağlamında geleneksel ve modern unsurların uyum sağlaması amacıyla tarihi evlerin otellere dönüşümünde yaşanan değişimler ortaya konmaktadır. Bu kapsamda araştırmada UNESCO tarafından koruma altında olan tarihi Safranbolu evlerinden, otel olarak hizmet verenler incelenmiştir. Geleneksel mimari öğeler ile günümüz tasarım anlayışının iç içe geçtiği bu dönüşüm sürecinde, iç mekanlarda gözlemlenen değişiklikler detaylı bir şekilde ele alınmıştır. Geleneksel yapı unsurlarının korunarak modern konfor ve estetik anlayışının entegre edildiği örnekler, Safranbolu evlerinin otel işlevi için nasıl günümüze uyarlandığını göstermektedir. Tarihi dokunun korunması ve aynı zamanda turistik konaklama ihtiyaçlarının dengelemesi bu örnekler üzerinden açıklanmaktadır.","PeriodicalId":413524,"journal":{"name":"Mobilya ve Ahşap Malzeme Araştırmaları Dergisi","volume":"45 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141347880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, hornbeam wood flour was added to the Polylactic Acid (PLA) polymer and then mixed in a twin-screw extruder, and then a wood-PLA composite filament with a diameter of 1.75 mm was produced. Then, test samples were printed from the produced wood-PLA composite filament at different printing speeds (40-50-60 mm/s) using a 3D printer. Tensile strength and hardness tests were performed to determine the mechanical properties of the 3D printed samples. According to the tensile strength test results, the tensile strengths of the 3D printed samples exhibited different values with the change in printing speed. The highest tensile strength value was determined as 23.02 MPa at a printing speed of 50 mm/s, and the lowest tensile strength value was 22.14 MPa at a printing speed of 40 mm/s. According to the Shore D test results, the lowest hardness value was measured as 85.33 at a printing speed of 40 mm/s, and the highest value was measured as 86.10 at a printing speed of 60 mm/s. According to the Differential Scanning Calorimetry (DSC) results, the crystallinity percentage of PLA first increased and then decreased with the increase in 3D printing speed. In addition, 3D printing speed did not have much effect on the melting temperatures of PLA.","PeriodicalId":413524,"journal":{"name":"Mobilya ve Ahşap Malzeme Araştırmaları Dergisi","volume":"40 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141345194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the tests, in addition to resistance values, stress and deformation at the elastic limit, II. zone length and total deformation were investigated. As a result of the experiments, it was observed that the materials lost some resistance after the maximum load was reached in LDN and steamed samples, but they continued to carry the load. This situation has led to the need to create two different resistance classes: maximum bending tensile strength and bending fracture resistance. The maximum stress in bending and fracture resistance in bending was found to be highest in air-dried samples, while the lowest was found in steamed samples. In examining the elastic limit resistance and deformations, the highest values were found in air-dried samples, while the lowest values were found in steamed samples. In determining the II. zone length, it was determined that the II. zone length of steamed samples gave the highest value, while air-dried samples gave the lowest value. In determining the total deformations, it was concluded that while the most deformation occurred in the steamed samples, the least deformation occurred in the air-dried samples.","PeriodicalId":413524,"journal":{"name":"Mobilya ve Ahşap Malzeme Araştırmaları Dergisi","volume":"44 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this objective, willow wood, inner bark, and outer bark flours were used as reinforcements at different weight percentages (17%, 27%, and 40%) in combination with polypropylene (PP) at varying weight percentages (44%, 58%, and 64%), along with a 2% compatibilizing agent. These constituents were processed in a twin-screw co-rotating extruder, with each treatment having a distinct mass proportion of reinforcement to polypropylene. Subsequently, test samples were fabricated using an injection molding machine from the obtained pellets. The mechanical properties of the resulting biocomposites were evaluated in accordance with ASTM standards. It was observed that the flexural and tensile properties of the WPCs improved with increasing inner bark content. Based on the findings of this investigation, a formulation comprising 27% wood, 27% inner bark, 44% polypropylene, and 2% compatibilizing agent (W/IB/PP/MAPP) can be recommended for construction applications requiring high mechanical strength. However, the other reinforced biocomposites exhibited notably lower notched impact strength compared to pure polypropylene.","PeriodicalId":413524,"journal":{"name":"Mobilya ve Ahşap Malzeme Araştırmaları Dergisi","volume":"35 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
