Preparation and Characterization of Fiber‐Reinforced Aluminum Phosphate/Silica Composites with Interpenetrating Phase Structures

Abstract

Glass fiber-reinforced aluminum phosphate (AP)/silica composites were prepared by hydrolyzing tetraethylorthosilicate (TEOS) in AP binder. The composites were hot pressed and cured at a temperature range between 1401C and 2001C with Al 2 O 3 as a curing agent. Microstructures of the prepared composites were examined using scanning electron microscopy. Flexural properties of the composites were investigated by a three-point bending test. It was found that the flexural strength of the prepared composites was significantly increased when appropriate concentrations of TEOS were used for hydrolysis. A microstructure study demonstrated that the improvement in flexural strength was due to the formation of an interpenetrating network structure between the two inorganic phases.

Amplitude‐dependent damping properties of ramie fiber‐reinforced thermoplastic composites with varying fiber content

“…The density of the 10RF/PP, 20RF/PP, and 30RF/PP composites are of 0.89, 0.93, and 0.99 g/cm 3 , respectively. Because the density of the composites improved with the increase of fiber content, so the interpenetrating network structure of fiber and PP matrix can be easier to form with the increase of fiber content , which can induce the stress of the matrix to be passed onto the fiber and thereby enhance the strength of the fiber reinforced composites . It can be also seen that the tensile modulus of the 10RF/PP, 20RF/PP and 30RF/PP composites have increased by 16.6, 40.1, and 48.6%, respectively, compared with that of the pure PP.…”

Improving Corrosion Behavior of Chemically Bonded Phosphate Ceramic Coating Reinforce with GO-TiO2 Hybrid Material

“…In addition, TiO 2 as one kind of metal oxide, can bond well with the binder during the sol-gel curing proceed of CBC. 18,19 However, TiO 2 cannot full cover the surface of GO. The part of the surface of GO without TiO 2 shows the poor interfacial adhesion with CBC leading to gaps between GO and CBC, which can be observed in Fig.…”

Anti-Corrosion Property of Glass Flake Reinforced Chemically Bonded Phosphate Ceramic Coatings

“…MgO can fully react with MAP solutions in the current pastes, so only the product of Mg 3 (PO 4 ) 2 and its XRD peaks remain in the GCBPCs. The main binding phase in the phosphate ceramic coatings originates in these reactions of Equations (2) and (3) [15,32]. The reason for the higher peak of Mg 3 (PO 4 ) 2 in GCBPCs is related to two aspects.…”
