DCB SPECIMENS TESTS
Original language description
The presented experimental work was focused on a sensitivity research of the FBG sensors. The technical problem to be solved is the impact or acoustic damage detection on an air intake carbon/epoxy composite structure. This structural part has no flight load bearing capacity, but it is loaded by acoustic pressure from the engine, resulting in presumed combination of mode I (opening) and mode II (shear) loading. FBG sensors are small enough to be embedded inside the prepreg composite structure. The embedding procedure was successfully tested, but there is a question of the sensitivity of such sensors in the given conditions. The first test of the damage detection capabilities of the FBG sensors was focused on the evaluation of the distance, from which can this sensor detect the delamination. Research was performed during the delamination growth testing in a mode I loading case using a double cantilever beam (DCB) specimens.
