| dc.description | Komposit berbahan serat alam seperti nanas, kenaf, dan sisal yang terus diteliti dan dikembangkan menjadi bahan alternatif pengganti serat sintetis, karena diketahui serat alam mudah didaur ulang sehingga dapat mengurangi dampak negatif terhadap lingkungan. Tujuan dari penelitian ini yaitu membuat bahan komposit polipropilen dengan filler serat alam (nanas, kenaf, dan sisal)/E-Glass/PP untuk mengetahui pengaruh jenis serat alam terhadap nilai ketangguhan impak dan daya serap air.
Komposit hibrid serat alam/E-glass/PP dengan perbandingan filler dan matriks polipropilena 30:70 (fraksi volume) difabrikasi dengan hand lay up dan metode hot press. Filler yang terdiri dari serat alam dan serat E-Glass (panjang 6 mm) yang telah di treatment divariasi dengan perbandingan serat nanas/E-Glass (2:1), serat kenaf/E-Glass (2:1), dan serat sisal/E-Glass (2:1). Pengujian ketangguhan impak (ASTM D 5942), pengujian daya serap air (ASTM D 570) dilakukan pada semua spesimen komposit. Selain itu, karakterisasi struktur patahan hasil hasil uji impak dan struktur mikro dari sisi penampang lintang masing-masing dilakukan denagan mikroskop optik dan scanning electron microscope (SEM).
Hasil penelitian menunjukkan bahwa nilai ketangguhan impak tertinggi terdapat pada komposit hibrid dengan nanas/E-Glass/PP dengan nilai ketangguhan impak 0,0193 J/mm2, hal ini dikarenakan serat nanas terdispersi merata didalam matriks PP dibandingkan sisal dan kenaf. Sedangkan hasil persentase daya serap air terendah terdapat pada komposit hibrid dengan variasi perbandingan sisal/E-Glass/PP sebesar 7,33 % selama 24 jam. Selain itu, hasil karakterisasi struktur mikro menunjukkan ikatan antara filler dan matriks saling mengikat dengan baik. | en_US |
| dc.description.abstract | Composite natural fibers pineapple, kenaf, and sisal has researched and developed into a replacement alternative synthetic fiber, because known natural fibers recycled so easy to reduce the negative impact on the environment.The purpose of this study of making a composite filler polypropylene with natural fibers ( pineapple, kenaf, and sisal )/E-Glass/PP to know the influence of natural fibers on the impact toughness and water absorption.
Composite hybrid a natural fiber/ E-Glass/PP with the ratio of to filler and a matrix polypropylene 30: 70 (volume fraction) fabricated with the hand lay up and methods of the hot press . The filler consisting of a natural fiber and for the fibers of e-glass (6 mm long) which have been treated with pineapple/E-Glass fiber (2: 1), kenaf/E-Glass fiber (2: 1), and sisal/E -Glass fiber (2: 1). Impact toughness test (ASTM D 5942), water absorption test (ASTM D 570) was carried out on all composite specimens. In addition, the structural characterization of the results and microstructure of each was carried out by optical microscopy and scanning electron microscope (SEM).
The results showed that the highest impact toughness value was found in hybrid composites with pineapple / E-Glass / PP with impact toughness value 0.0193 J / mm2, this was because pineapple fibers were dispersed evenly in the PP matrix compared to sisal and kenaf. While the lowest percentage of water absorption was found in hybrid composites with a variation of sisal / E-Glass / PP ratio of 7.33% for 24 hours. In addition, the results of microstructure characterization show that the bond between filler and matrix is mutually binding. | en_US |
