Optical fiber sensors (OFSs), which rely on evanescent wave sensing for the early detection of the diffusion of water and hydrochloric acid through glass fiber-reinforced polymers (GFRPs), have been developed and tested. Epoxy and GFRP specimens, in which these sensors were embedded, were subjected to tests in artificial sea water and hydrochloric acid. The sensors were able to detect the diffusion of chemicals through the epoxy and GFRP samples on the basis of a drop in the reflected signal from the tip of the optical sensor probe. Water and hydrochloric acid diffusion coefficients were calculated from gravimetric measurements and compared with the experimental response of the OFSs. Furthermore, mechanical tests were carried out to assess the influence of the sensors on the structural integrity of the GFRP specimens.

Tensile properties and impact damage tolerance of hemp fiber and chopped strand mat (CSM) glass fiber composites have been evaluated and compared. The absolute and specific tensile properties of CSM glass fiber composites were found to be much superior to hemp fiber composites. Impact damage tolerance of hemp fiber composites was also quite low compared to CSM glass fiber composites. They lost almost half of their intrinsic strength and stiffness following an impact of 2 J energy. Considerable evidence of matrix fracture, interfacial debonding, and fiber fracture was found in the fracture surface. Following an impact at 4 J energy, hemp fiber composites lost almost 70% of their intrinsic strength and stiffness. In comparison, CSM glass fiber composites were able to endure an impact of 20 J energy for 70% reduction in their intrinsic strength and stiffness.
