“…Figure 3 shows the changes in the flexural properties (flexural strength and modulus) affected by alkali-treated sisal fiber and by adding MCC. It is described earlier [20] that modification of natural fiber surface by alkali solution can enhance the fiber/matrix interface bonding because of the surface roughness improvement [28].…”

“…The fiber was left to soak in a 6% NaOH solution at room temperature (RT) for 36 h and then neutralized in 1% CH 3 COOH for one hour to improve interfacial interaction with the matrix. It is then followed by immersing the fiber in distilled water for about 36 h before being washed off with flushing water and dried [20]. Subsequently, the treated sisal fiber was chopped to around 4 mm in length.…”

The study on polymethyl methacrylate (PMMA)-based composites in dental applications have gained much interest in recent years, resulting in many interesting studies worldwide. In those research, various filler types of reinforcing PMMA have been studied extensively. This study combines the microcrystalline cellulose (MCC) particles (0, 1, 2, 3, 5 vol.%) and sisal fiber to strengthen PMMA. We investigate their effects on the flexural, impact, hardness, compressive strength, water absorption, and thermal properties of (MCC)/sisal/PMMA hybrid composites. XRD, SEM, universal testing machine (UTM), hardness Vickers, TGA, and ANSYS Workbench 2022 R1 software are utilized to characterize the properties of the composite. Adding MCC to alkali-treated sisal/PMMA decreases the flexural and impact strengths but increases the hardness. Adding 1 and 2 vol.% MCC produces maximum flexural and impact strength and hardness values. Simulation on a composite added with 1% MCC by applying a full force load of 14.4 N yields compressive strength of 42.56 MPa. Thermal stability of all composites with and without MCC shows similarity until 250°C but gradually degrades at over 250°C, particularly for composites with MCC. Besides, as the addition of MCC increases, the water absorption also increases, with the lowest value of 37.54 µg/mm3 obtained by the composite added with 1 vol.% MCC, which is within the range of the standard dental materials.

“…Hal ini akan menurunkan sifat mekanis komposit serat alam. Oleh karena itu, metode paling mudah untuk meningkatkan sifat mekanis komposit adalah dengan memberi perlakuan alkalisasi pada permukaan serat [4]. PMMA adalah bahan polimer sintetis non-crystalline yang umum digunakan dibidang orthopedic sebagai bone cement untuk implant imbuhan dan merombak tulang yang hilang.…”

“…Pertama serat abaka dicuci bersih dengan air mengalir dan dikeringkan didalam oven pada suhu kurang lebih 100C selama 30 menit. Kemudian serat abaka dialkalisasi dalam larutan 6% NaOH pada suhu ruangan selama 36 jam [4] dan dinetralkan dengan larutan 1% asam asetat. Untuk perlakuan terhadap serat karbon dilakukan dengan perendaman serat karbon dalam nitrogen cair (liquid N2) selama 10 menit [10].…”

Serat karbon dan abaka sebagai penguat komposit hybrid polymethyl methacrylate (PMMA) adalah salah satu bahan fungsional. Komposit ini akan bermanfaat untuk bahan alternatif prosthesis karena kekuatan mekaniknya yang relatif tinggi, ringan, dan biokompatibel dengan jaringan manusia. Pada penelitian ini komposit karbon/abaka/PMMA difabrikasi menggunakan metode hand-lay-up dan cold press molding dengan tekanan 2,185 MPa selama 60 menit, dengan tujuan untuk mengkarakterisasi sifat tarik komposit dengan variasi perbandingan serat karbon dan abaka 1:2, 1:1 dan 2:1, serta fraksi volume serat 20%. Sebelum fabrikasi komposit, serat karbon diberi perlakuan dengan direndam dalam nitrogen cair (liquid N2) selama kurang lebih 10 menit. Sedangkan serat abaka diberi perlakuan alkalisasi dalam larutan 6% NaOH pada suhu kamar selama 36 jam. Sifat kimia serat abaka sebelum dan sesudah alkalisasi dianalisis dengan Fourier transformed infrared (FTIR) spectroscopy. Uji tarik dilakukan pada semua spesimen komposit mengacu pada ASTM D638. Hasil uji tarik disimulasikan dengan perangkat lunak Autodesk Inventor 2019 dan Nastran-In CAD 2019 untuk mengetahui kelayakan bahan untuk aplikasi prosthesis. Nilai kuat tarik dan modulus elastisitas tertinggi dari hasil penelitian ini ditunjukan pada komposit dengan perbandingan serat karbon dan abaka 2:1 masing-masing yaitu 105,71 MPa dan 5,24 GPa. Sedangkan hasil simulasi menyatakan bahwa material komposit karbon/abaka/PMMA dapat direkomendasikan sebagai bahan alternatif prosthesis.
