Fındıkkabuğu tozu takviyeli/polimetilmetakrilat kompozitlerin kırılma ve eğilme davranışlarının incelenmesi
Examining the breaking and bending behaviors of the polymethylmethacrylate composites reinforced with hazelnut shell powder

Kenan Büyükkaya [1]


Çalışmanın amacı, gevrek matrislerde fındıkkabuğunun toklaştırma etkisini eğilme ve farklı kırılma yöntemleri ile ortaya koymaktır. 50µ partikül boyutuna sahip %5, %10, %15 ve %20 ağırlık oranlarında fındıkkabuğu tozu takviyeli /Polimetilmetakrilat kompozitler üretildi. Üretilen polimer kiriş numunelere, ısıl kür işleminden sonra, a/W= 0,1, 02, 03, 04, 0,5 başlangıç çentikleri açıldı. Çentiksiz ve tek kenardan çentik açılmış kompozit numunelerin mode I kırılma davranışları üç nokta eğme testi uygulanarak ortaya konuldu. Kritik Gerilme Şiddet Faktörü (KIC) J- integral, Başlangıç Çentik Derinliği ve Komplians metotları ile hesaplandı.  Bununla birlikte eğilme modülü ve eğilme gerilmeleri de belirlendi. HNSF/ PMMA kompozitlerin mikro yapısı XRD, FTIR ve SEM çalışmaları ile ortaya konuldu. Çalışmanın sonuçlarına göre, fındıkkabuğu tozu / Pmma kompozitlere eklenen tozların %10 katkı oranında eğilme kuvveti, eğilme modülü ve kırılma tokluğunu arttırdığı belirlenmiştir.

The objective of the present study is to reveal the toughening effect of the hazelnut shell on the brittle matrices by using the bending and breaking methods. The polymethylmethacrylate composites reinforced with hazelnut shell powder with 50µ particle size at the weight concentrations of 5%, 10%, 15%, and 20% were prepared. The polymer beam samples were exposed to heat cure procedure and the initial notches were created at a/W=0.1, 0.2, 0.3, 0.4, and 0.5. The Mode I breaking behaviors of the notched at single edge and non-notched composite samples were examined by using three-point bending test. The critical stress intensity factor (KIC), J-integral, initial notch depth, and compliance methods were used in calculations. Besides them, the bending module and bending stress values were calculated. The microstructures of HNSP/PMMA composites were determined by using XRD (x-ray diffractometer), FTIR (Fouirer Transform Infrared Spektrofotometre), and SEM (scanning electron microscope) analyses. According to the results obtained, it was determined that the bending strength, elasticity module, and fracture toughness values increased at 10% additive ratio for the HNSP (hasel nut shell flour)/PMMA (polymethylmethacrylate) composites.
