Effect of basalt fiber surface silane coupling agent coating on fiber-reinforced asphalt: From macro-mechanical performance to micro-interfacial mechanism

In this paper, two types of fiber surface treatment methods, namely heat treatment and chemical coupling, were used to improve the basalt fiber surface properties. The basalt fiber surface was heated under 250Celsius degree for 30minites, and then was treated by silane coupling agent ethanol solution with different concentrations. X-ray photoelectron spectroscopy (XPS) was utilized to study the surface chemical compositions of basalt fiber after treatments. The XPS analysis indicated that chemical bonds between basalt fiber and KH-550 have occurred, and silanols were adsorbed to the surface of basalt fibers by an ether linkage between the silanols and the hydroxyl groups of the fibers. When the concentration of KH-550 is 0.8wt%, the optimal bonding condition is formed between basalt fiber and silane coupling agent.

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.

Silane Coupling

In this paper, a continuous glass fiber-reinforced polypropylene prepreg was prepared by fiber treatment with a silane coupling agent and MAH-g-PP resin. Continuous glass fiber-reinforced polypropylene sheets were made from prepreg and PP mats by hot-pressing; they displayed exceptional performance. This paper studies the effects of maleic anhydride grafting on the polypropylene crystallinity and MAH-g-PP content in the prepreg, and the mechanical properties of the composites. The results showed that modifying PP with maleic anhydride decreased the tacticity of the polypropylene molecular chain, which reduced the crystallinity and melting point. An excellent interface formed between the polypropylene and fiber after the glass fiber was treated with a silane coupling agent and MAH-g-PP resin. The mechanical properties of the polymer materials displayed more favorable properties as MAH-g-PP content increased; the ideal MAH-g-PP content was 50%.
