The unique sensing features of the tilted Fibre Bragg Grating (TFBG) as a single three-parameter optical sensor are demonstrated in this work, to monitor manufacturing process composite materials produced using Vacuum Assisted Resin Transfer Moulding (VARTM) process. Each TFBG can measure simultaneously and separately strain, temperature refractive index (RI) material where fibre is embedded. A...

Accomplishments Analysis of the current modeling approach for CRTM, as well as for some of the physical phenomena involved in the process, such as preform deformation, revealed certain weaknesses in the numerical approach and, more importantly, significant gaps in fundamental understanding of underlying physics. New governing relations for the general Liquid Composite Molding (LCM) and, in part...
