“…LPGFS are realized by inscribing a diffraction grating into the core or on the cladding of a single‐mode optical fiber operation is accomplished exploiting the coupling process between the incident fundamental mode with core guided propagation and co‐propagating through the core and cladding modes by scattering on the diffraction Bragg grating having a 10–1000 µm period. Such diffraction Bragg gratings are denoted as long period gratings (LPG) . The coupling between co‐propagating core and cladding mode represents an energy transfer from the fundamental core mode to the cladding modes.…”

“…Among the fiber optic sensors used for transforming composite materials as smart ones, the long period grating fiber sensors (LPGFS) used as manufactured or in self‐interference setups (SILPG) are of special interest because of their increased sensibility. LPGFS and/or SILPG are used as embedded in the polymer matrix of the composite materials for the resulting reduced volume of the resulting mechanical parts …”

The purpose of this paper is to present a new method of detecting cracks that appear in the polymer matrix of a smart composite material using a self-interference long period grating (SILPG) fiber sensor setup. Strain and torsion deformations of the polymer matrix induced by the cracks effects on SILPG are exploited for crack detection. Different other features of the crack mechanism that induce a change in the SILPG status and response are identified. The response of SILPG fiber sensor under host composite material host crack action is investigated and simulated for defining the functional limits of the composite material. SILPG fiber sensor is considered as embedded in polymer matrix of composite material. SILPG is operated as the signal source of the smart composite material feedback loop.

In this study a type of polymeric composites from melting poly propylene as a basic substance with Palm fronds powder were prepared. Evaluation of polymeric composites was done by studying some of it is mechanical properties, which included:Yong modulus (E), Impact Strength (I.S), Brinell hardness (B.H) and Compression Strength (C.S). The polymeric composites were studied before and after reinforcment by comparing between them. There was an increase in resistance of Yong modulus (E), Impact Strength (I.S), Brinell hardness (B.H) and compression Strength (C.S). Also, the effect of some acids were studied such as (HCl, H2SO4, HNO3) with concentrations of (0.5N; 1N and 1.5N) respectively. The physical properties of absorbance and poly propylene's diffusion coefficient were studied before and after reinforcment, The results showed an increase in values of these properties with increasing concentration of acid and time of polymer's immersion in the acidic solution.

The concentration of infiltrated water molecules into polymer matrix of composite materials is an important mechanical and chemical functional parameter of smart composite materials during exploitation in various research, medical, industrial, and security applications and it is important to design a setup as simple and as efficient as possible for measuring and monitoring this important parameter. The paper presents simulation/design results obtained using self-interference long period grating fiber sensors in measuring and monitoring the concentration of infiltrated water molecules into polymer composite materials. The investigated long period grating fiber sensors are used as they are or mounted in interferometric setups. Self-interference long period grating fiber sensors are manufactured by inscribing diffraction gratings into or on single mode commercial communication optical fibers and are used in smart composite materials as signal generators of their feedback loop being embedded into the polymer matrix.
