Environmental influence on the fracture strength of coated glass fibers

摘要

AbstractThe effect of the environment on the fracture strength of coated glass fibers is described. Simple expressions relating the thermodynamic work of adhesion, in the presence and absence of stress to the permanence of the composite, are derived. The need for interactions other than dispersion‐type interactions between silica and coating systems is emphasized. A prognosis is offered for achieving a permanently bonded structure, provided that reasonable wetting can be facilitated at the oxide–coating interface or that there is generated a strongly bound species to the silica, shifting the potential locus of fail
