摘要：

The laboratory scale pultrusion process is developed to fabricate smart fiber reinforced polymer (FRP) materials. The shear and tensile properties, i.e. strength and modulus, of the pultruded carbon/vinylester and glass/vinylester rods with and without optical fibers are determined. Microstructural analysis of the smart pultruded FRP is carried out using the optical microscope and scanning electron microscope (SEM). The interfaces between the resin matrix and the acrylate and polyimide coated optical fibers are examined and interpreted in terms of the coating's ability to resist high temperature and its compatibility with resin matrix. A micromechanical model of composite material, taking into account the misorientation of fibers, is developed and the corresponding constitutive equation is derived. The effect of small fiber misorientation angle on the tensile and shear effective moduli of composite material is investigated. The micro stress heterogeneity in fibers and matrix of composite is analyzed. (C) 1997 Elsevier Science Ltd. All rights reserved.
