Acoustic Emission Activity in Ductile Fiber Reinforced Cementitious Composites
This study was performed in the framework of a research program focused in the development of high tenacity polypropylene (PP) fibres for the reinforcement of cementitious composites. Precedent reports have demonstrated how micromechanical modelling was used to attain significant improvements with respect to the macroscopic properties of cementitious composites. These improvements have been bas...
متن کاملAn Acoustic Emission Study of Flax Fiber-Reinforced Polypropylene Composites
Sensitivity to crack propagation in flax fiber-reinforced polypropylene (PP) composites has been examined on SEN-T specimens. The sound waves that arise due to loading have been investigated with the acoustic emission method. Linear functional relationship has been revealed between the number of acoustic events that occur during loading and the fracture toughness. It has also been observed that...
متن کاملResponse of fiber reinforced composites to underwater explosive loads
An in-house developed, verified and fully validated three-dimensional finite element code, with rate dependent damage evolution equations for anisotropic bodies, is used to numerically ascertain the damage developed in a fiber-reinforced composite due to shock loads representative of those produced by an underwater explosion. Three internal variables characterize damage due to fiber/matrix debo...
متن کاملFlexural monitoring of carbon fiber/epoxy composite by acoustic emission
Carbon / epoxy composite is one of the most useful polymer matrix composites that has special properties such as high strength-to-weight ratio, high hardness, high corrosion resistance, Resistance to nuclear radiation has high consumption in different industries such as aerospace industry. Therefor monitoring of loading of this type of composite is important. In order to determine failure mecha...
