Development of natural fiber reinforced composite prepreg

Development of natural fiber reinforced composite prepreg / Saifulmajdy Ahmad Zahiri
Secara umumnya, komposit adalah bahan yang dibuat dengan mencampurkan dua atau lebih bahan-bahan konstituen sifat-sifat yang berbeza untuk meningkatkan kelebihan bahan. Bahan-bahan komposit sangat digunakan pada kebelakangan ini disebabkan oleh keupayaan sifat-sifat tertentu yang disesuaikan, seperti tinggi nisbah kekuatan-berat, rintangan kakisan, sifat-sifat yang tidak boleh terbakar, rintangan haus dan sebagainya. Keperluan untuk komposit bertetulang gentian yang boleh diperbaharui tidak pernah tersebar luas seperti pada masa kini. Gentian semulajadi menawarkan penjimatan kos dan pengurangan ketumpatan apabila dibandingkan dengan gentian kaca. Walaupun kekuatan gentian semulajadi tidak sama seperti gelas, sifat-sifat tertentu adalah setanding. Dalam kajian ini, sifat-sifat mekanik bahan komposit prepreg dan layang basah menggunakan gentian kelapa sawit, telah dianalisis dan dinilai dengan teliti. Walau bagaimanapun, kebanyakan itu akan memberi tumpuan kepada kemungkinan untuk menghasilkan komposit prepreg serat semulajadi dan ciri-cirinya. Kaedah fabrikasi termasuk pengacuan mampatan, pemisahan serat dan proses pengawetan resin yang digunakan untuk menghasilkan spesimen kawalan dan prepreg. Kemudian, sifat mekanik spesimen diuji menggunakan ujian tegangan. Terdapat beberapa masalah yang ditemui dalam kajian ini kerana membuat prepreg adalah proses yang kompleks. Isu-isu diselesaikan melalui penyelidikan dan pembangunan lanjut spesimen. Setelah spesimen dihasilkan, ujian tegangan dilakukan untuk analisis dan proses penilaian. Hasil fabrikasi spesimen menunjukkan bahawa fabrikasi prepreg bahan semulajadi adalah berpotensi walaupun sifat mekaniknya kurang dari fiberglass. Sebagai kesimpulan, prepreg serat semulajadi boleh dikomersialkan. Walau bagaimanapun, kajian lanjut diperlukan untuk menghasilkan komposit serat semula jadi yang konsisten dan lebih baik pada masa akan datang. _______________________________________________________________________________________________________ Generally, composite is a material made by mixing two or more constituent materials of different properties to enhance the advantages of the materials. Composite materials are highly utilized in lately due to their ability of tailored specified properties, such as high strength-to-weight ratio, corrosion resistance, inflammable properties, wear resistance and etc. The need for renewable fiber-reinforced composites has never been as prevalent as it currently is. Natural fibers offer cost savings and reduction in density when compared to glass fibers. Even though the strength of natural fibers is not as great as glass, the specific properties are comparable. In this study, mechanical properties of biocomposite materials of wet hand layup and prepreg using palm oil fiber, are to be analyzed and evaluated thoroughly. However, most of them will focus on the possibility to produce natural fiber prepreg composite and its characteristics. Fabrication methods includes compression molding, fiber separation and resin curing process used to manufacture the control specimens and prepreg Then, the mechanical properties of the specimens are tested using tensile test. There are a few issues encountered in this study as making prepreg is a complex process. The issues were solved through further research and development of the specimen. After the specimen produced tensile test was carried out for analysis and evaluation process. The results of specimen fabrication show that natural fiber prepreg fabrication is possible although its mechanical properties are less than fiberglass. In conclusion, natural fiber prepreg is possible to be developed. However, further research is needed to produce consistent and better natural fiber composite in the future.
