heal.abstract	The thermal-expansion coefficients of filled unidirectional composites were analytically investigated. To improve the analysis a new theoretical model was introduced. In previous publications the boundary-interphase concept was used, which was defined as the zone between the fibres and the matrix material. This zone contains both areas of adsorption-interaction between the layer of the polymeric matrix and the neighbouring layers in the glass-fibres, as well as the areas of any mechanical imperfection, such as; voids, microcracks, impurities, and other defects. In the present investigation it was considered that the interphase material was an inhomogeneous substance with properties varying continuously from the fibre surface to the bulk matrix. The variation of the thermal-expansion coefficient in the area of the boundary interphase was analytically investigated. Expressions for both the longitudinal and transverse thermal-expansion coefficients of the composite were derived. The predictions of the continuous-interphase model were compared with the results of Schapery and agreed satisfactorily. © 1981.	en
