Characterization of structure and physical properties of centrifugal glass fiber felts and preparation technology

Abstract

In this paper, glass fiber felts are fabricated by centrifugal-spinneret-blow process. Swing cylinder is designed to obtain a micro-layer structure, and the phase difference of two swing cylinders is π/2 + 2kπ. Tensile strength, flexural rigidity, and thermal conductivity of various glass fiber felts are investigated. The experimental results indicate that the tensile strength of micro-layer glass fiber felts and random glass fiber felts is 0.015 MPa and 0.013 MPa, respectively. In addition, the tensile strength of glass fiber felts is also improved with the increase of the density and the resin content of glass fiber felts. The micro-layer structure decreases the flexural rigidity of glass fiber felts, and the flexural rigidity of glass fiber felts with micro-layer and random structures is 43.4 g.cm and 101.3 g.cm, respectively. The mean thermal conductivity of glass fiber felts with micro-layer and random structures is 31.57 mW/m·k and 35.69 mW/m·k, respectively.

Correlation between glass fiber suspension characteristics and physical of glass fiber felt: Role of beating time and speed

“…As a typical kind of inorganic non-metallic material fiber, glass fibers are with high strength, high modulus [1], oxidation resistance, corrosion resistance, high-temperature resistance, and other characteristics, which also have excellent performance of sound insulation, heat insulation, and electrical insulation [2]. Papermaking process is considered as the most significant nonwoven preparation technology because of its high efficiency and recyclability [3], compared with electrospinning [4] and hot pressing [5].…”

Synthesis of waterborne epoxy resin with diethanolamine-assisted succinimide for improving the strand integrity of polyimide filament

“…High-performance fibers such as aramid fiber [1,2], carbon fiber [3,4], basalt fiber [5,6], glass fiber [7,8], and polyimide [9][10][11][12][13][14][15] have broad application prospects in the military, transportation, construction, electronic, aerospace, and electrical fields, due to their high strength, high modulus, and high-temperature resistance. Polyimide (PI) filament is a species of high-performance fiber with the imide ring structure in the molecular chain.…”
