Flexural and post-fire flexural properties of eggshell hybrid glass fibre reinforced polymer (gfrp) composites

Flexural and post-fire flexural properties of eggshell hybrid glass fibre reinforced polymer (gfrp) composites / Nithikorn Suvanamporn
Penggunaan bahan komposit polimer telah meningkat dengan ketara sepanjang dekad yang lalu. Sifat unik bahan komposit bertetulang serat membolehkan aplikasi dalam pelbagai bidang teknologi seperti angkasa, pesawat, marin dan automotif. Serat binatang komposit kulit telur dianggap mempunyai potensi penggunaan sebagai agen pengukuhan dalam bahan komposit polimer kerana faedah prinsip mereka seperti kekuatan yang baik dan kekukuhan, kos rendah, dan bahan yang mesra alam, boleh degradasi, dan boleh diperbaharui. Kacang telur ayam dihancurkan, kisar dan disaring untuk granul saiz 75 μm untuk tetulang dalam matriks. Jenis komposit yang berbeza dibuat menggunakan (0,15,20) wt% serbuk kulit telur dengan serat E-kaca dan matriks epoksi. Teknik layang tangan digunakan untuk mengarang komposit kaca epoksi dengan serbuk kulit telur. Selepas menyebarkan serbuk kulit telur dalam epoksi, pengeras akan ditambahkan yang akan memulakan proses menyambung silang. Kemudian spesimen dibiarkan selama 24 jam pada suhu bilik. Sifat mudah terbakar dan lenturan kulit telur hybrid plastic gentian bertulang kaca komposit sebagai fungsi kandungan pengisi dalam saiz zarah (75 μm) dikaji. Ujian dijalankan mengikut piawaian ASTM. Reaksi komposit berkandungan serbuk kulit telur yang tidak mudah terbakar diperiksa, ia menunjukkan bahawa pengurangan secara beransur-ansur apabila kandungan pengisi meningkat kerana komposisi kimia dan sifat kulit telur. Hasil eksperimen telah menunjukkan peningkatan dalam modulus kelenturan kulit telur hybrid plastic gentian bertulang kaca komposit yang baru direka ini. Oleh itu, perkembangan bahan komposit epoksi berkandungan telur telur dengan sifat mekanik yang baik dan ringan yang berpotensi tinggi ini dapat memberi faedah dan meperluaskan lagi bidang kejuruteraan. _______________________________________________________________________________________________________ The use of polymer composite materials has increased considerably over the last decade. The unique properties of fibre reinforced composite materials enable their application in various technological areas such as space, aircraft, marine and automotive. Animal fibre of eggshell composites are considered to have potential use as reinforcing agents in polymer composite materials because of their principle benefits such as good strength and stiffness, low cost, and be an environmentally friendly, degradable, and renewable material. Chicken eggshells are crushed, ground and sieved for granules of size 75 μm for reinforcement in the matrix. Different types of composites are fabricated using (0,15,20) wt % of eggshell powder with E-glass fibre and epoxy matrix. Hand lay-up technique is adopted to fabricate epoxy glass composites with eggshell powder. After dispersing the eggshell powder in epoxy, the hardener is added which then will initiate cross-linking process. Then specimens are cured for 24 hours at room temperature. Post-fire and flexural properties of eggshell hybrid GFRP composites as a function of filler content in the particle sizes (75 μm) are investigated. The tests are conducted according to ASTM standards. Post-fire of the composites as a function of filler content examined for 2 minutes showed gradual reduction when the filler content increases because of the chemical composition and nature of egg shell. Experimental result has shown improvements in Flexural Modulus of this newly processed Eggshell Hybrid GFRP composite. Hence the development of epoxy/eggshell particulate composites material with good mechanical properties and light weight which is relevant to the engineering applications has the potential to be achieved.
