Fabrication of woven metal fibre reinforced glass matrix composites

Abstract

Abstract. A processing route has been developed for the fabrication of metallic fibre mat reinforced glass matrix composites. For the model experiments reported here, a commercially available satin woven stainless steel 316L fibre mat was used as the reinforcement and soda-lime glass as the matrix. The process involves two steps: (1) the infiltration of the intra-and inter-tows regions of the fibre mats with silica sol using electrophoretic deposition and (2) the fabrication of a composite by cold uniaxiat pressing and pressureless sintering of impregnated fibre mats sandwiched between layers of the matrix glass powder. The sintering took place in air at 670 ~ and composite materials of sufficient integrity could be obtained without damaging the fibres. The deposited silica remained amorphous at the processing temperature providing a porous interface between the glass matrix and the metallic reinforcement. Observation of fracture surfaces revealed that both fibre pull-out and fibre deformation occur, which should lead to a significant toughness enhancement. The presence of the interfacial silica layer, deposited using electrophoresis, is thought to be responsible for this behaviour.

Highly Impact‐Resistant Silk Fiber Thermoplastic Composites

“…In ref. [17], it is, e.g., found that tough metal fibers in a brittle glass matrix give a higher composite toughness when the adhesion is low. A similar observation about the level of adhesion will be made in this article.…”

Mechanical bone growth stimulation by magnetic fibre networks obtained through a competent finite element technique

“…Unlike previous work about this specific fibre material, the present study combines it with a matrix material to a fibre-matrix composite. Static, conventional applications of fibre-matrix composites have been proposed for composites of bioglass 20 , 21 or cordierite 22 , 23 . In the field of biomedical engineering, metallic 24 , 25 and since then also non-metallic 26 , 27 fibre networks have been tested for their ability to improve bone cement mechanics.…”

Constant Current Electrophoretic Infiltration Deposition of Fiber‐Reinforced Ceramic Composites

“…Conventional wisdom would suggest that conductive fibers would best serve as the deposition electrode, i.e., the matrix particles deposit directly on the fibers. Carbon fibers, 5 carbon‐coated SiC fibers, 6–9 nickel‐coated carbon fibers, 10,11 stainless‐steel fibers, 12–15 and polyoyrrole‐coated fibers 17 have been used. Most experiments were conducted in an aqueous suspension under a constant voltage.…”

“…Several techniques have been used to introduce matrices into fiber preforms, i.e., chemical vapor infiltration (CVI), 1 solution infiltration including sol–gel and polymer precursor approaches, 1 pressure filtration (PF), 2 vibration‐assisted infiltration, 3,4 and electrophoretic deposition (EPD) 5–15 . Both CVI and solution infiltration have low penetration efficiency and hence it is difficult to obtain a dense green body; it is also difficult by pressure filtration.…”
