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 better characteristic than its compotition material.

Bending strength composite with straight fiber having variation value, because straight fiber pattern more prone to delamination of fiber matriks.
