Glass/polypropylene sensor yarns integration during weaving of 2D structure

Monitoring the structure of composites inside or on its surface and crash tests are difficult to obtain in the same time. Pretest was made by insertion of four developed sensor yarns in weft and four sensor yarns in warp direction during weaving of 2D structures at the ARM loom. The weaving step of 2D fabrics due to checking the thermo-forming consolidation of sensor yarns inserted is considered as important factor for several future applications. Therefore, sensor yarns of one meter total length were made from E- glass/polypropylene (GF/PP) commingled yarn by roll to roll mechanism with plexiglass bath to obtain even coating thickness and uniform distribution. Mostly developed sensors work after its production and integration in 2D structures before consolidation, while its validation after 2D fabric consolidation has to be improved.
