Effect of Fiber Type and Volume Fraction on Fiber Reinforced Concrete and Engineered Cementitious Composite Mechanical Properties

open access: yesBuildings, 2022
Engineered cementitious composites (ECC) are an ultra-ductile cement-based composite material reinforced with short randomly distributed fibers. It differs from fiber reinforced concrete (FRC) in that it has a distinct ductile behavior. The study aims to

Mechanical Strength of Stripped Optical Fiber [PDF]

open access: yes, 2019
A novel removal technique of silica optical fiber coating with chemical stripping gel was used. We observed that the fiber strength decreases from 5.48 to 4.96 GPa in the case of tensile test and from 0.06 to 0.05 GPa in the case of bending test when the coating was removed from the cladding surface.
