Electromagnetic Performance Analysis of Glass Fiber Composite Radomes with Different Structures and Fiber Orientations

Öz

Glass fiber composite radomes are important structural elements in radar and communication systems, and their electromagnetic permeability and mechanical strength are critical. Radomes are special structures that protect antennas from environmental effects and should not prevent radio wave propagation. For radar and antenna systems to operate properly, signals must be transmitted without interference and, if reflected, received accurately without substantial loss. In this study, the effects of different fiber orientations and sandwich structure on the electromagnetic performance of glass fiber composite radomes were investigated. Several experiments were conducted on radome samples prepared with different fiber orientations (monolithic and sandwich). According to the experimental results, it was observed that the glass fiber orientations and sandwich structures considered did not have a significant adverse effect on the electromagnetic permeability performance of the radomes.

Farklı Yapıda ve Fiber Oryantasyonda Cam Elyaf Kompozit Radomlarda Elektro Manyetik Performans Analizi

Öz

Bu çalışmada, farklı fiber oryantasyonlarının ve sandviç yapının cam elyaf kompozit radomların elektromanyetik performansına etkisi incelenmiştir. Cam elyaf kompozit radomlar, radar ve iletişim sistemlerinde kullanılan önemli yapı elemanlarıdır ve elektromanyetik geçirgenlikleri ile mekanik dayanımları kritik öneme sahiptir. Radom, antenleri çevresel etkilerden koruyan ve radyo dalgalarının geçişini engellemeyen özel yapılardır. Radar ve anten sistemlerinin sağlıklı çalışabilmesi için sinyallerin bozulmasız ve kayıpsız yayınlanması ve yansıyan sinyallerin de bozulmasız ve kayıpsız alınması gerekmektedir. Elektromanyetik geçirgenlik ihtiyacı ve endüstride kullanılabilecek malzemelerin kısıtlı olması nedeniyle mevcut malzemelerde yapılabilecek iyileştirmeler radar sistemlerinin istenilen şekilde çalışmasına önemli katkı sağlayacaktır. Çalışmada, farklı fiber oryantasyonlarına sahip, monolitik ve sandviç tipi olarak hazırlanan radom numuneleri üzerinde deneyler yapılmıştır. Deney sonuçlarına göre, dikkate alınan cam elyaf oryantasyonları ve sandviç yapıların radomların elektromanyetik geçirgenlik performansı üzerinde önemli bir etkisi olmadığı gözlenmiştir.
