In this chapter, glass and glass-ceramic matrix composites containing carbon nanotubes (CNTs) are discussed with an emphasis on their production, properties, microstructures and applications. Composite manufacturing routes require both CNT/matrix powder preparation techniques and their densification by suitable sintering processes. Physical, mechanical, functional and technological properties of the composites are evaluated, including density, hardness, elastic modulus, fracture strength and toughness, electrical and thermal conductivity, wear and friction resistance, and thermal shock, cycling and ageing resistance. Microstructural features are typically characterized by X-ray diffraction and scanning and transmission electron microscopy. Based on the characteristics obtained, potential applications of the composites are considered, together with a discussion of the unresolved manufacturing challenges and desirable, but still unattained, properties. © 2013.

Shirshova N, Bismarck A, Carreyette S, et al., 2013, Structural supercapacitor electrolytes based on bicontinuous ionic liquid-epoxy resin systems, JOURNAL OF MATERIALS CHEMISTRY A, Vol: 1, Pages: 15300-15309, ISSN: 2050-7488
This paper presents the development of multifunctional materials that perform a structural role whilst simultaneously storing electrical energy as a supercapacitor. Two structural carbon fibre woven electrodeswere separated by a woven glass fibre layer, and infused with a multifunctional polymer electrolyte. Following characterisation of electrochemical and compressive performance, working structural supercapacitor prototypes were demonstrated. Since the relative mechanical and electrical demands are application specific, an optimisation methodology is proposed. Multifunctional composites were achieved, which had compressive moduli of up to 39 GPa and capacitances of up to 52 mF g 1.

Bismarck A, Carreyette S, Fontana QPV, et al., 2012, Multifunctional epoxy resin for structural supercapacitors, ECCM 2012 - Composites at Venice, Proceedings of the 15th European Conference on Composite Materials
Polymer-based electrolytes based on commercially available epoxy resins were prepared through the addition of a liquid electrolyte, a solution of a lithium salt in an ionic liquid. The polymer monoliths were characterized using impedance spectroscopy, 3-point bending test, scanning electron microscopy (SEM) and nitrogen adsorption (BET). The balance of ionic conductivity and flexural modulus is crucially dependent on the relative proportions of epoxy resin to electrolyte. Also the effect of the liquid electrolyte on curing kinetics and processing was assessed by complex viscosity measurements and differential scanning calorimetry (DSC). Only one out of the three resins investigated exhibited a significant acceleration effect.
Qian H, Diao HL, Houllé M, et al., 2012, Carbon fibre modifications for composite structural power devices, ECCM 2012 - Composites at Venice, Proceedings of the 15th European Conference on Composite Materials
This research project focuses on the development of new multifunctional composite materials, which allow energy storage functionality to be imbued upon low weight structural components. A crucial requirement for efficient structural energy storage composites is the development of structural carbon fibre electrode materials that possess high electrochemical surface area and stability whilst supporting high mechanical loads. In the present work, a variety of carbon fibre modifications were investigated, including chemical activation, carbon nanotube (CNT) sizing and CNT-grafting. The effects of these different modification methods on the fibre surface microstructure, electrochemical, and mechanical performance were studied and compared. In the most promising cases, up to a hundred-fold improvement in electrical storage capacity was achieved. Furthermore, single fibre tensile tests demonstrated that the intrinsically excellent mechanical properties of the carbon fibre were retained after the modifications.
