Reinforcing effect of aramid fibers on fatigue behavior of SBR/aramid fiber composites

Polymer Testing, 2019
Abstract This paper investigates the correlation between fatigue performance and static tensile behavior of fiber reinforced rubber materials and presents change of fiber reinforced effect during fatigue process. A rough aramid fiber (AF) surface, which is helpful for combining AF and rubber matrix, was achieved by etching AF in NaOH/CH3CH2OH ...

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 ...

Electrospinning of p-Aramid Fibers

Macromolecular Materials and Engineering, 2015
Electrospun poly (p-phenylene terephthalamide) (PPTA) fibers with diameters between 275 nm and 15 µm were obtained from anisotropic solutions, albeit that the spinning process was difficult to control. Key solution parameters like conductivity, surface tension, and viscosity were used to compare the spinnability of these anisotropic solutions with ...
