Paper Abstract

Embedding the Polymer fibers, whose limiting strain is about 10%, into the composite materials to form the intelligent materials is researched. Encapsulating polymer fibers with epoxy resin of identical elastic modulus and embedding them into the structures during the molding process. The Demodulating system based on F-P filter method is advanced to analyze the shift of wavelengths with high speed DSP TMSC3206713 as data processor. Precise PIN photoelectric cell-InGaAs-PIN-PD753, is used to transform the output of F-P filter to electricity and two high speed A/D chips ADS1610 are used to collect the outputs of PINs. C2H2 GC for dynamical wavelength demarcation is advanced for more precise metrical results. Strain and damage condition information is transferred to the master computer as the references of health monitoring of weapon equipments. The primary experiments indicate that when 2 fibers with 3 gratings on each are embedded into the material, the intensity of materials don't weaken obviously. During the molding process of high temperature and high pressure, reflected spectrum of FBGs in hot stretching environment is analyzed through Spectrum Instrument. Fibers do not be ruptured and their sensitivity of strain is well. F-P demodulating system realizes strain resolution by 2με when it works at 200Hz.
