ABSTRACT
This chapter focuses on the issues where the bonding in textiles has special characteristics. An extensive overview of these models on the micromechanics scale and macromechanics scale can be found in various general references. Bonding processes associated with the special structure of a multifilament yarn in a cement matrix were resolved qualitatively in the context of studies of glass–fiber-reinforced cement composites that were produced by the spray method. The composites are manufactured by chopping the yarn and spraying it on a mold along with a mortar matrix. This is a quantitative manifestation of the special microstructure of a cementitious matrix reinforced with glass-bundled filaments: the external sleeve filaments were well bonded to the matrix, while the inner core ones were largely free, resulting in a bonding mechanism that provided ductility. The understanding of the microstructure of the bundle in relation to its bonding was investigated in-depth by Banholzer, Banholzer and Brameshuber, and Banholzer et al.
