Evaluation of test methods used to characterize fiber reinforced cementitious composites [PDF]
, 2013 This paper describes an investigation of fiber reinforced cementitious composites in terms of their behavior under tensile and flexural loading. Flexural testing and subsequent derivation of the tensile stress-deformation response from the flexural test ...

Performance enhancement of nylon/Kevlar fiber composites through viscoelastically generated pre-stress [PDF]
, 2013 Kevlar-29 fibers have high strength and stiffness but nylon 6,6 fibers have greater ductility. Thus by commingling these fibers prior to molding in a resin, the resulting hybrid composite may be mechanically superior to the corresponding single fiber ...

Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]
, 2018 Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...
