Reinforcing Fillers

The use of natural plant fibers as reinforcing fillers in fiber-polymer composites has drawn much interest in recent years. Natural plant fibers as reinforcing fillers have several advantages over inorganic fillers such as glass fibers; they are abundant, readily available, renewable, inexpensive, biodegradable, of low density, and of high specific strength. Hemp fibers are one of the most attractive natural plant fibers for fiber-reinforced composites because of their exceptional specific stiffness. In this review, we summarize recent progress in developments of the hemp fiber reinforced composites such as hemp fiber reinforced unsaturated polyester (UPE), hemp fiber reinforced polypropylene (PP), hemp fiber reinforced epoxy composites, and so on, illustrate with examples how they work, and discuss their intrinsic fundamentals and optimization designs. We are expecting the review to pave the way for developing fiber-polymer composites with higher strength.

Silane Coupling

E-glass fiber merupakan fiber reinforcement yang sering digunakan di kedokteran gigi karena berikatan baik dengan polimer melalui silane coupling agent, meningkatkan kekuatan mekanis dan tidak sensitif terhadap kelembaban. Ketersediaan E-glass fiber dental di Indonesia terbatas dengan harga relatif mahal. Glass fiber non dental banyak tersedia di Indonesia dengan harga terjangkau, yang biasa digunakan pada pembuatan panel gypsum dan komponen otomotif. Tujuan penelitian ini adalah mengetahui pengaruh komposisi glass fiber non dental terhadap kekuatan fleksural fiber reinforced composites. Bahan yang digunakan dalam penelitian ini adalah E-glass fiber dental (Fiber-splint, Polydentia SA, Switzerland), glass fiber non dental A (LT, China), B (CMAX, China) dan C (HJ, China), flowable composite (CharmFil Flow, Denkist, Korea) dan silane coupling agent (Monobond S, Ivoclar Vivadent, Liechtenstein). Subjek dibagi dalam 5 kelompok: tanpa fiber, E-glass fiber dental, glass fiber non dental A, B dan C . Uji kekuatan fleksural berdasarkan ISO 10477. Hasil yang diperoleh dianalisis menggunakan ANAVA satu jalur. Hasil penelitian menunjukkan rerata kekuatan fleksural (MPa) terendah pada kelompok tanpa fiber (126,18±5,21) dan tertinggi pada kelompok glass fiber non dental A (208,03±8,32). Hasil ANAVA satu jalur menunjukkan pengaruh bermakna dari komposisi fiber terhadap kekuatan fleksural (α < 0,05). Kesimpulan penelitian: Kandungan SiO2, Al2O3 dan alkali tanah oksida (MgO dan CaO) yang tinggi pada glass fiber meningkatkan kekuatan fleksural dari fiber reinforced composites.
