Abstract
Industri dirgantara secara kontinu berupaya meningkatkan performa pesawat dari segi struktur material. Bahan komposit berperan penting dalam komponen kedirgantaraan karena memiliki sifat yang unggul. Namun, jika matriksnya terbuat dari polimer ketika terpapar temperatur tinggi, matriks organik terurai. Sehingga diperlukan lapisan pelindung termal. Dalam penelitian ini dilakukan pembuatan Skin Barrier (SB) keramik Al2O3 dengan binder Na2(SiO2)x.(H2O)x sebagai lapisan perlindungan komposit Carbon Fiber Reinforced Polymer (CFRP) sebagai preparasi untuk proses lanjutan Thermal Barrier Coating (TBC). Metode dilakukan adalah hot pressing yaitu pemberian tekanan dan pemanasan pada spesimen secara bersamaan. Dalam penelitian ini dianalisis pengaruh fraksi massa perbandingan antara keramik Al2O3 dengan binder Na2(SiO2)x.(H2O)x adalah 1:2,5; 1:2,75; dan 1:3 serta temperatur proses hot pressing 100°C, 130°C, dan 160°C. Selanjutnya dianalisis pengaruhnya terhadap daya lekat dan konduktivitas termal dari struktur lapisan skin barrier. Karakterisasi material yang dilakukan adalah Scanning Electron Microscopy (SEM), Thermal Conductivity Meter (TCM), Pull-off test, Thermogravimetric Analysis (TGA), dan Fourier-Transform Infrared Spectroscopy (FTIR). Hasil analisis menunjukkan skin barrier dengan fraksi massa keramik dan binder 1:2,5; 1:2,75; 1:3 yang diberi perlakuan hot press pada temperatur 130°C dan 160°C serta fraksi 1:3 pada temperatur 100°C sesuai dengan kualifikasi. Dengan konduktivitas termal material terendah adalah SB160/3 yaitu 0,1605 W/mK yang menyebabkan penurunan temperatur dari 500°C ke 46,45°C dan untuk daya lekat terbaik ketiga spesimen pada masing-masing temperatur adalah komposisi 1:2,75 dengan nilai daya lekat optimum pada spesimen SB100/2,75 yaitu 0,797 MPa.

The aerospace industry continuously strives to improve aircraft performance in terms of material structure. Composite materials play an essential role in aerospace components because they have superior properties. However, when exposed to high temperatures, the organic matrix decomposes if the matrix is made of polymer. So a thermal protective layer is needed. In this research, the Al2O3 ceramic skin barrier was made with Na2(SiO2)x.(H2O)x as a CFRP composite protection layer to prepare further thermal barrier coating. The method used is hot pressing, applying pressure and heating the specimen simultaneously. In this study, the effect of mass fraction 1:2,5; 1:2.75; and 1:3 comparison between Al2O3 ceramics and Na2(SiO2)x.(H2O)x binder was analyzed, and hot pressing process temperatures of 100°C, 130°C, and 160°C on the adhesion and thermal conductivity of the Al2O3 ceramic skin barrier layer structure with Na2(SiO2)x.(H2O)x binder. The material characterization methods were Scanning Electron Microscopy (SEM), Thermal Conductivity Meter (TCM), Pull-off test, Thermogravimetric Analysis (TGA), dan Fourier-Transform Infrared Spectroscopy (FTIR). The analysis results show that in its application to protect CFRP, skin barrier with ceramic mass fraction and binder 1:2,5; 1:2.75; 1:3, which is hot pressed at a temperature of 130 and 160 and a 1:3 mass fraction pressed at a temperature of 100°C meet the qualifications required. The lowest thermal conductivity of the material is SB160/3 which is 0.1605, which causes a decrease in temperature from 500°C to 46.45°C, and for the adhesion strength of the Al2O3 ceramic skin barrier layer structure, the data trend shows the best adhesion of the three specimens on each temperature is a composition of 1:2.75 with the optimum adhesion value to the SB100/2.75 specimen is 0.797 MPa
