Tensile properties of composite laminates due to fuel attack

Tensile properties of composite laminates due to fuel attack / Nurul Atiqah Ishak
Tujuan utama kajian ini ialah untuk mengkaji kesan minyak tanah, biodiesel, air suling dan keadaan suhu bilik terhadap tingkah laku penyerapan komposit dan juga sifat mekanikal komposit yang diperkukuhkan dengan E-glass. Komposit lamina ini dibuat melalui bahan E-glass yang terdiri daripada dua jenis resin iaitu polyester dan epoxy resin. Pelbagai cara telah dijalankan termasuk lah tradisional “Hand-Layup”, “Resin Infusion” dan juga “Vacuum Resin Transfer Molding”. Kandungan fiber di dalam setiap komposit telah dikara menggunakan kaedah ketumpatan dan juga pembakaran resin. Kesemua sampel telah direndamkan di dalam tiga jenis kandungan dan ketepatan “Fick’s Law” telah dikaji. Kesemua sampel telah ditinggalkan sehingga semuanya benar-benar tepu. Ujian ketegangan telah dijalankan dengan menggunakan Instron Tensile Machine (UTM). Semua data dan maklumat daripada ujian mekanikal telah diplot kan di dalam graf yang terdiri daripada “stress versus strain”, dan carta bar “ average tensile stress”. Data yang didapati telah dikaji dan perbandingan mengenai kedua-dua resin yang direndam di dalam tiga keadaan telah dibuat. Didapati bahawa kesemua specimen yang telah direndam di dalam minyak tanah, biofuel, air suling dan dalam keadaan suhu bilik tidak mempunyai perubahan yang ketara terhadap ‘tensile stress’ dan ‘tensil modulus’ dan oleh itu komposit yang diperkukuhkan dengan E-glass ini sesuai digunakan untuk membuat tangki minyak bagi aplikasi marin dan aeroangkasa. _______________________________________________________________________________________________________ The main purpose of this study is to investigate the effects of kerosene, biofuel, distilled water and room temperature condition on the moisture behavior and mechanical properties of the E-glass reinforced composite. A laminate composite from the E-glass composite material is fabricated that consist from two type of resins which are polyester-based resin and epoxy-based resin. A variety method has been conducting which are the traditional hand layup, resin infusion (RI) and vacuum resin transfer molding. The fiber content for each methods is calculated by using density method and resin burn-off method. The specimens is immersed in the three type of solution and the accuracy of Fick’s Law on moisture diffusion is studied. All specimen were left until it is fully saturated respective to its solution. A tensile test was performed subsequently by using the Universal Tensile Machine (Instron) (UTM). The data obtain from the mechanical test were plotted in a graphical approach by using the tensile stress versus strain graph and average tensile stress bar chart. The data obtained were studied and a comparison of data are being made between both type of resin and also between the three different solutions. It was found that there are no significant change in tensile stress and tensile modulus for all the specimen being immersed in kerosene, biofuel and distilled water and in room condition hence this E-glass fiber reinforced composite can be used in manufacturing the fuel tank structure both in marine and aerospace application.
