Özet:

 In the presented study, the effect of overlap length on the damage behavior in adhesive joints produced with polylactic acid PLA joint samples produced at different printing angles and filling ratios was experimentally examined. In line with the motivation of the study, PLA samples were produced at two different angles 0 and 45 and two different infill ratios 100 and 75. Single-lap joint samples with 12.5 mm, 25 mm and 37.5 mm overlap lengths were produced using the produced PLA samples. The mechanical properties of bulk PLA samples produced at different angles and filling ratios were determined by tensile testing in accordance with the ASTM D638 standard. The mechanical properties of the produced adhesively bonded joint PLA samples were determined considering the ASTM D1002 standard. When the results obtained were evaluated, it was observed that the filling ratio and printing angle had a significant effect on the mechanical properties of bulk PLA samples, and the failure loads of the joint samples produced in this direction also varied depending on the infill ratio and printing angle. It was determined that the tensile strengths of bulk samples produced at 0 and 45 printing angles increased by approximately 6.3 and 7.4, respectively, as the infill ratio increased from 75 to 100. Moreover, it has been determined from experimental studies that the failure load increases with increasing overlap length. In the joint samples produced using PLA samples with a 0 printing angle and 100 infill ratio, it was determined that the failure loads of the joints increased by approximately 56 and 117, respectively, as the overlap length increased from 12.5 mm to 25 and 37.5 mm.

 Sunulan çalışmada, farklı baskı açıları ve dolgu oranlarında üretilmiş PLA bağlantı numuneleriyle üretilmiş yapıştırma bağlantılarında bindirme uzunluğunun hasar davranışı üzerine etkisi deneysel olarak incelenmiştir. Çalışmanın motivasyonu doğrultusunda, iki farklı açıda 0 ve 45 ve iki farklı dolgu oranında 100 ve 75 PLA numuneler üretilmiştir. Üretilen numuneler kullanılarak 12,5 mm, 25 mm ve 37,5 mm bindirme uzunluğuna sahip tek tesirli bağlantı numuneleri üretilmiştir. Farklı açı ve dolgu oranlarında üretilen bulk PLA numunelerin mekanik özellikleri ASTM D638 standardına uygun olarak çekme testi ile belirlenmiştir. Üretilen bağlantı numunelerinin mekanik özellikleri ise ASTM D1002 standardı dikkate alınarak belirlenmiştir. Elde edilen sonuçlar değerlendirildiğinde, dolgu oranı ve baskı açısının bulk numunelerin mekanik özellikleri üzerine önemli etkisinin olduğunu, bu doğrultuda üretilen bağlantı numunelerinin hasar yüklerinin de dolgu oranı ve baskı açısına bağlı olarak değiştiği gözlemlenmiştir. 0 ve 45 baskı açılarında üretilen bulk numunelerde doluluk oranının 75den 100e çıkmasıyla çekme dayanımlarının sırasıyla yaklaşık 6,3 ve 7,4 oranında arttığı belirlenmiştir. Bununla birlikte, bindirme uzunluğunun artması ile hasar yükünün arttığı deneysel çalışmalardan belirlenmiştir. 0 baskı açısı ve 100 doluluk oranında PLA numuneler kullanılarak üretilen bağlantı numunelerinde, bindirme uzunluğu 12,5 mmden 25 ve 37,5 mmye artmasıyla bağlantıların hasar yüklerinin sırasıyla yaklaşık 56 ve 117 oranında arttığı belirlenmiştir.
