AUTOGENOUS MICROWAVE WELDING OF POLYMETHYMETHACRYLATE MATERIAL

Öz

   Polymethylmethacrylate (PMMA) sheets were autogenously welded without using heat dissipating graphite or siliconcarbide, under 2MPa load, for 70, 80, 90, and 100 seconds duration times. The shear tests were applied to welded samples to find the bonding strength, the highest bonding strength of 3.1MPa was found in 80 second welded sample.  The weld region of samples were observed for optical and scanning electron microscopy.

POLİMETİLMETAKRİLAT MALZEMENİN MİKRODALGA İLE OTOJEN KAYNAĞI

Öz

   Mikrodalga kullanılarak polimetilmetakrilat (PMMA) levhalar birbirine arada herhangi bir ısı çeken grafit veya silisyum karbür malzeme olmadan, otojen olarak 2 MPa yük altında 70, 80, 90 ve 100 saniye süreyle kaynaklanmıştır. Kaynaklanan parçaların bağlanma mukavemetleri kesme deneyi ile mekanik olarak test edilmiş, en iyi bağlanmanın 80 saniye süreyle kaynaklanan numunelerde olduğu görülmüştür. Bağlanma kuvveti 80 saniye süreyle kaynaklanan numune için 3,1 MPa olarak tespit edilmiştir. Kaynaklanmış parçaların optik mikroskop ve taramalı elektron mikroskobu kullanılarak kaynak bölgesi incelenmiştir.
