Abstract
Komposit adalah gabungan dari dua material penyusun
yang menghasilkan material baru dengan karakteristik yang lebih
baik dari material awalnya. Material komposit mulai banyak
digunakan dan dikembangkan di berbagai bidang, baik itu untuk
penelitian, industri dan otomotif, bahkan kedokteran. Dalam
dunia kedokteran sendiri mulai banyak dilakukan penelitianpenelitian mengenai komposit, seperti pada sendi, tulang, dan gigi
manusia. Misalnya saja penelitian mengenai material gigi
pengganti pada manusia tujuannya untuk memperololeh material
yang aman dan nyaman digunakan.
Pada penelitian ini dilakukan pada material gigi tiruan
dari resin akrilik berpenguat serat E-glass. Dan akan divariasikan
dari pola susunan serat penguat tersebut dari tanpa hadirnya serat
penguat pada material, kemudian berpenguat serat dengan pola
susunan teratur dan acak pada material gigi tiruan. Pada tahap
pertama diawali dengan pembuatan material uji, untuk kemudian
dilakukan pengujian bending sesuai standar pengujian ASTM
D790, sehingga diketahui nilai tegangan bending dari material
gigi tiruan tersebut. Setelah didapatkan nilai bending maksimal
dari material gigi tiruan yang divariasikan pola susunan serat
penguat dengan fraksi volume 7%. Maka akan dilakukan analisis
mengenai pengaruh dari pola susunan serat yang acak dan teratur
terhadap kekuatan bending dari material gigi tiruan.Dari hasil penelitian didapatkan nilai tegangan bending
maksimal yang diperoleh oleh material tanpa serat penguat
sebesar 42,43 N/mm². Material dengan tambahan serat penguat
berpola acak sebesar 51,53 N/mm². Material dengan tambahan
serat penguat berpola teratur antara 47,08 N/mm² - 64,62 N/mm².
Kekuatan bending komposit serat teratur memiliki variasi harga,
karena karena struktur teratur lebih mudah mengalami delaminasi
matrik serat.

Composite is the combination of two material that having
better characteristic than its compotition material. Composit
material has been used in many sector such as research,
automotive industry, and medical. the use of composite in
medical sector usually as synthetic bone especially artificial teeth.
Synthetic teeth that made of composite material having good
quality, safe, and comfortable.
This research is about artificial teeth material that made
of acrylic resin with E-glass fiber. There are three variation of
fiber reinforced patternt which is without fiber, straight fiber
pattern, and random fiber pattern. The first process is create a
specimen made of acrylic resin. Then the speciment will be
testing using bending stress test acording to standart test of
ASTM D790. After the maximum bending tension of artificial
teeth with reinforced fibers pattern variety at 7% volume of
fiberglass speciment known, the next step is analyze the effect of
fiber reinforced pattern to bending tension of artificial teeth
speciment.
The result of this research the maximum bending tension
value obtained by materials without fiber at 42,43 N/mm2..
materials with additional random fiber pattern at 51.53 N/mm2
.
Material with additional straight fiber pattern between 47,08
N/mm2 to 64,62 N/mm2
. Bending strength composite with straight Composite is the combination of two material that having

prone to delamination of fiber matriks.
