Effect of the mold on the residual strain field monitored with optical fibers sensors in resin transfer molding processes

摘要: Fiber Bragg gratings provide accurate and non-intrusive strain sensors. They can be embedded into fibrous preforms to deliver real-time information on ongoing processes. The possibility of using the strain-induced birefringence fiber extract effective state composite at end process has already been demonstrated. This effect used estimate residual field in composites manufactured by resin transfer molding. fields calculated with associated optoelastic three-dimensional model are shown compare well classical laminated plate theory. then here order study influence nature mold plates furthermore infer kinematic conditions applied part during cooling two different molds, an aluminum a HexTool™ mold. It is demo...
