In this work, dry-jet wet spun ultra-high molecular weight polyethylene (UHMWPE) fiber and multi- coating layer were used to enhance the mechanical properties of fiber sensor and sensing stability which is resistance and gauge factor. The shell parts of the fiber sensor, double polyurethane (PU) layer and MWCNT/Carbon black (CB) hybrid filler system, were formed on the UHMWPE core fiber by dip coating method. Electrical resistance and strain sensitivity of the fiber sensors were measured using a LCR meter. Finally, the prepared fiber sensor was embedded into glass fiber reinforced composite to evaluate load bearing capacity.
