Influence of aviation fuel on the room temperature and post-fire compression properties of sandwich composite materials

Influence of aviation fuel on the room temperature and post-fire compression properties of sandwich composite materials / Muhammad Addin Hassan
Tujuan utama projek tahun akhir ini adalah untuk menyiasat pengaruh bahan bakar terhadap sifat kemampatan bahan sandwic komposit dalam kondisi suhu bilik dan pendedahan api. Bahan yang digunakan untuk membuat sandwic komposit adalah serat E-glass, plastik honeycomb sebagai teras specimen dan epoxy. Kaedah untuk membuat sandwic komposit adalah kaedah tradisional „hand lay-up‟. Ujian rendaman dan kemampatan pendedahan api terhadap spesimen perlu dijalankan untuk mengetahui tentang sifat-sifate sandwic komposit. Jenis bahan bakar yang digunakan adalah biofuel dan minyak tanah. Bahan bakar ini digunakan untuk menentukan bagaimana pengaruh bahan bakar terhadap sifat sandwic komposit. Bagi ujian kemampatan terhadap pendedahan api, spesimen perlu dipanaskan dengan pencucuh api pada masa yang berbeza dan kemudian dimampatkan dengan menggunakan mesin Instron. Ujian pembakaran komposit dijalankan untuk mencari peratusan kadar serat dalam bahan sandwic komposit. Peratusan kadar serat yang terkandung dalam bahan sandwic komposit adalah di dalam sekitar 48%. Sandwic komposit mempunyai peratusan daya penyerapan yang lebih tinggi dalam biofuel berbanding di dalam minyak tanah.Ujian kemampatan terhadap sandwic komposit yang normal dan direndam telah dijalankan dan didapati sifat kemampatan bagi sandwic komposit berkurangan kerana kekuatan antara serat dan matriks menjadi lemah setelah direndam. Kekuatan sandwic komposit semakin berkurang apabila masa pendedahan api semakin meningkat. Ini didapati bahawa kesemua spesimen yang telah direndam di dalam bahan bakar dalam keadaan suhu bilik dan pendedahan api tidak mempunyai sebarang perubahan dari segi kekuatan dalam kemampatan _______________________________________________________________________________________________________ The main purpose of this final year project is to investigate the influence of aviation fuel on the room temperature and post-fire compression properties of sandwich composite. The materials used to fabricate sandwich composite is E-glass fibre, plastic core and epoxy matrix. The method used to fabricate composite is wet hand lay-up. In order to find the properties of sandwich composite, the specimen undergo immersion test and post-fire compression test. The aviation fuel is used in immersion test to determine how it will influence the properties of sandwich composite. For post-fire compression test, the specimen is heated with fire torch and then compressed using Instron testing machine (UTM). The experimental burn-off testing was conducted in order to calculate the fibre volume fraction of sandwich composite materials. It is found that the fibre volume fraction of sandwich composite is around 48%. Sandwich composite in biofuel has higher moisture absorption percentage compared to kerosene. The compression testing between normal and immersed sandwich composite was conducted and it is found that the compressive properties of immersed composite decrease as the bonding between fibre and matrix become weak. For post-fire compression testing, the compressive strength reduced with different heat exposure time. It was found that there are no significant changes in compressive strength in room temperature and high temperature for all specimen being immersed in aviation fuel.
