✦ Synopsis

The effect of reinforcement geometry on the thermal expansion behavior of particulate-flied bis-maleimide matrix composites has been examined both experimentally and theoretically. To clarify the geometrical effect, a wide range of reinforcement shapes, from short fiber to flake, was used. The comparison was made between experimentally obtained thermal expansion coefficients and those theoretically predicted by the use of Eshelby's equivalent inclusion method. The predicted values were shown to agree reasonably well with the experimental values. An attempt was then made to obtain the relation between the reinforcement geometry and processability condition. It was found that spherical-particle-filled composites exhibited superior thermal expansion behavior compared with short-fiber-or flake-reinforced composites from the viewpoint of processability, including void-free formation. In part II of this paper the effect of multi-reinforcing phases on the thermal expansion behavior of a composite is studied and the results of the following paper are compared with those of the present paper.
