Increasing Low-Velocity Impact Strength of Glass Fiber Sandwich Composites with Nanoparticle Reinforced Adhesive

Öz:
The use of sandwich composite structures in the aerospace industry is increasing. Therefore,Improving the impact and other mechanical properties of sandwich composite panels (SCP) isessential for aviation safety. In the manufacture of SCPs, bonding with the lower and uppersurfaces of the honeycomb structure is provided by bonding connections. So, by improving themechanical properties of the adhesives used in SCP, the mechanical rigidity of the wholestructure will be enhanced. In this study, sandwich composite panels were produced using glassfiber reinforced composite, three different adhesives (pure polyurethane, 0.1% and 0.2% multiwalled carbon nanotube reinforced polyurethane) and an aluminum honeycomb with a celldiameter of 8.86 mm. Low-velocity impact tests were applied to the manufactured sandwichcomposites at the initial energy level of 50 J. After impact tests, load-time, load-deflection andenergy-time graphs were obtained, and the effect of multi-walled carbon nanotube (MWCNT)contribution was evaluated. Also, the effect of the MWCNT addition on impact properties wasdetermined by making a damage analysis. It was observed that the carbon nanotube addition tothe polyurethane adhesive increased the maximum contact force by 3%, improving the lowspeed impact properties of SCPs.

Cam Fiber Sandviç Kompozitlerin Düşük Hızlı Darbe Mukavemetinin Nano Parçacık Takviyeli Yapıştırıcı Kullanılarak Artırılması

Öz:
Sandviç kompozit yapıların havacılık ve uzay endüstrisinde kullanımı artmaktadır. Sandviç kompozit panellerin (SKP) darbe ve diğer mekanik özelliklerinin geliştirilmesi havacılık emniyeti açısından önem arz etmektedir. SKP’lerin imalatında bal peteği yapının alt ve üst yüzeyler ile bağı yapıştırma bağlantıları ile sağlanmaktadır. SKP’de kullanılan yapıştırıcıların mekanik özelliklerinin iyileştirilmesi ile bütün yapının mekanik rijitliği iyileştirilmiş olacaktır. Bu çalışmada cam fiber takviyeli kompozit, üç farklı yapıştırıcı (saf poliüretan, ağırlıkça %0,1 ve %0,2 çok cidarlı karbon nano tüp katkılı poliüretan) ve 8,86 mm hücre çapında alüminyum bal peteği kullanılarak sandviç kompozit paneller üretilmiştir. Üretimi yapılan sandviç kompozitlere 50 J ilk enerji seviyesinde düşük hızlı darbe testleri uygulanmıştır. Darbe deneyleri sonrasında yük-zaman, yük-sehim ve enerji zaman grafikleri elde edilerek çok cidarlı karbon nano tüp (ÇCKNT) katkısının etkisi değerlendirilmiştir. İlaveten, hasar analizi yapılarak ÇCKNT katkısının darbe özelliklerine etkisi belirlenmiştir Poliüretan yapıştırıcıya karbon nano tüp katkısının en büyük temas kuvvetini %3 oranında artırarak SKP’lerin düşük hızlı darbe özelliklerini iyileştirdiği görülmüştür.
