"... Fiber Bragg grating (FBG) hybrid sensors and thermocouples measure strain and temperature simultaneously during and after cure of asymmetric cross-ply composite laminates. FBG strain sensor is used to measure strain; FBG temperature sensor and thermocouple are used to measure temperature. The charac ..."

"... This article presents the real-time strain measurement of a composite liquid hydrogen (LH2) tank using fiber Bragg grating (FBG) sensors. The tank was composed of carbon fiber reinforced plastic (CFRP), and an aluminum liner was fabricated by the filament winding method and mounted on a reusable roc ..."

"... In this paper, we present a simultaneous measurement of strain and temperature during and after cure of unsymmetric cross-ply composite laminate using fiber optic sensors. Fiber Bragg grating/extrinsic Fabry-Perot interferometric (FBG/EFPI) hybrid sensors are used to measure those measurands. The ch ..."

"... Abstract In this paper, we present the simultaneous measurement of the strain and temperature during cures of various composite laminates using fiber optic sensors. Fiber Bragg grating/extrinsic Fabry-Perot interferometric (FBG/EFPI) hybrid sensors were used to measure those measurands. The charact ..."

"... Piezoelectricwaferactive sensorsare small, inexpensive, noninvasive, elasticwavegenerators/receptors that canbe easily affixed to a structure. Piezoelectric wafer active sensor installation on the health-monitored structure is an important step thatmay have significant bearing on the success of the ..."

"... A new sensor for unsteady force measurements of pitching and plunging airfoils using Fiber Bragg Gratings (FBG) in a water channel facility has been the developed. Load cells having four or five FBG sensors written in a single optical fiber have been developed to measure the strain at flexures desig ..."
