Abstract
Unsaturated Polyester Resin merupakan termoset polimer yang
banyak digunakan. Poliester memiliki ketahanan kimia,
ketahanan korosi dan sifat mekanik yang tinggi. Komposit adalah
gabungan dari dua material atau lebih yang memiliki ikatan
secara mekanik dengan tujuan untuk membentuk material sesuai
dengan yang diinginkan serta harganya yang rendah. Dalam
material komposit serat, fungsi utama serat adalah sebagai
penopang kekuatan dari komposit sehingga tinggi rendahnya
kekuatan komposit sangat tergantung dari serat yang digunakan.
Serat kaca adalah bahan yang ringan, kuat, dan sering
digunakan dalam berbagai industri karena sifat mereka yang
sangat baik. Dalam penelitian ini, dilakukan proses pembuatan
komposit polyester/serat kaca kontinu dengan variasi fraksi berat
serat kaca 0, 10, 20, 30, dan 40 wt %. Serat kaca yang digunakan
memiliki diameter rata-rata ~11 μm dan jenis yang digunakan
continuous roving. Metode pencampuran komposit poliester/serat
kaca dilakukan dengan hand lay-up. Hasil uji FTIR menunjukkan
adanya ikatan kimia antara polyester, katalis, dan serat kaca.
Hasil pengujian tarik tertinggi pada terdapat pada komposisi
40% serat kaca sebesar 159,32 MPa. Penambahan serat kaca
pada komposit dapat meningkatkan stabilitas thermal komposit.

Unsaturated Polyester Resin is a thermosetting polymer that is
widely used. Polyesters are having chemical resistance, corrosion
resistance and high mechanical properties. Composite is a
combination of two or more materials that have a mechanical
bond with the aim to establish in accordance with the desired
material and the price is low. In the fiber composite material, the
main function is as a pillar of strength fiber composite so that the
level of the composite strength is highly dependent on the fiber
used. Glass fibers are a material that is light, strong, and are
often used in various industries because of their excellent
properties. In this study, the process of making a composite
polyester / continuous glass fiber with a variation of the weight
fraction of glass fibers 0, 10 ,20, 30, and 40 wt%. Glass fibers
used have an average diameter of ~11 μm and the type used
continuous roving. A method of mixing the composite polyester /
glass fiber made by hand lay-up. The FTIR test result indicates a
chemical bond between the polyester, catalyst, and glass fiber.
The highest tensile test results on the composition contained 40%
glass fibers at 159.32 MPa. The addition of the glass fibers in the
composite can enhance the thermal stability of the composite.
