Abstract

Bu çalışmada, çekirdek yapı malzemesi olarak bitki bazlı ve yenilenebilir kaynaklardan üretilen polilaktik asit (PLA) ve petrol bazlı üretilen Akrilonitril-butadien-stiren (ABS) seçilmiş ve yüzey kapakları polyester/cam fiber kompozitler kullanılmış ve sandviç levhalar üretilmiştir. Çekirdek yapı malzemesi üretiminde baskı işleminin hızlı ve kolay yapılabilmesi gibi avantajlarından dolayı ergiyik biriktirme yöntemi kullanılmıştır. Çekirdek malzemeleri 3B yazıcı kullanılarak üç farklı hücre boyutu ve üç farklı hücre yüksekliğinde imal edilmiştir. Numunelere 3 nokta eğilme testleri uygulanmış ve kuvvet-yer değiştirme grafikleri elde edilmiştir. Elde edilen sonuçlar grafikler halinde sunulmuştur. Üç nokta eğilme deneyleri sonrası hasar tipleri incelenmiş ve baskın hasar tiplerinin katmanlar arası kopma ve kayma hasarı olduğu görülmüştür. Bu durumun önüne geçilebilmesi 3 boyutlu yazıcı kullanılarak ergiyik biriktirme yöntemi ile üretilen PLA termoplastik kullanılarak üretilmiş numunelere ikinci aşamada sıcaklık ve basınç uygulanmıştır. PLA malzemeden üretilen numunelerin ABS malzemeden üretilen numunelere göre daha yüksek eğilme dayanımına sahip oldukları görülmüştür.

Abstract

In this study, polylactic acid (PLA) produced from plant-based and renewable resources and Acrylonitrile-butadiene-styrene (ABS) produced petroleum-based were selected as core building materials and polyester/glass fiber composites were used for surface covers and sandwich composite sheets were produced. In the production of core building materials, fused deposition modeling has been used due to its advantages such as fast and easy printing. Core materials were fabricated in three different cell sizes and three different cell heights using a 3D printer. Three-point bending tests were applied to the samples and load-displacement graphs were obtained. Obtained results are presented in graphics. After three-point bending tests, damage types were examined and it was seen that the dominant damage types were interlayer rupture and shear damage. In order to prevent this situation, temperature and pressure were applied to the samples produced using a 3D printer in the second stage. It was observed that the samples produced from PLA material had higher flexural strength than the samples produced from ABS material.
