Improved Electrical Conductivity of CFRP by Conductive Silver Nano-particles Coating for Lightning Strike Protection
The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...
متن کاملComputational modeling of micro-crack induced attenuation in CFRP composites
A computational study is performed to determine the contribution to ultrasound attenuation in carbon fiber reinforced polymer composite laminates of linear elastic scattering by matrix micro-cracking. Multiple scattering approximations are benchmarked against exact computational approaches. Results support linear scattering as the source of observed increased attenuation in the presence of micr...
متن کاملModeling damage in polymeric composites
We postulate that dominant damage modes in a fiber-reinforced laminated composite are fiber breakage, matrix cracking, fiber/ matrix debonding, and delamination/sliding. The first three damage modes are represented by internal variables with their development governed by constitutive relations. The delamination/sliding failure mode is presumed to initiate at a point on an interface between two ...
متن کاملMultiscale Analysis of Lightning Strike Maps
Electric power utilities face increasing demand for service reliability. Since cloud-toground lightning strikes are among the most frequent yet least understood causes of service interruption, predicting the geographical and temporal distribution of the lightning strikes can help power system planners and designers improve the protection of new and existing transmission lines. Lightning is the ...
متن کاملBasal ganglia hemorrhage related to lightning strike.
We describe a case of bilateral basal ganglia hemorrhage after a lightning strike to the head documented by a CT scan. Review of the literature shows this to be the most common brain imaging finding that can be attributed to a lightning strike. Several mechanistic theories are discussed, with the most plausible one being related to preferential conduction pathways through the brain.
