Transient Heat Flow Across Uni-Directional Fibers in Composites

Abstract

Transient heat flow in fibrous composites is important in determining the depth of heat penetration and temperature gradients near surface layers. A pervious report dealt with heat flow parallel to the fiber axis. This research is concerned with heat flow perpendicular to the uni-directional fibers. Temperature responses under the condition of a constant surface heat load are calculated by a finite-difference approach. The rise of the composite surface temperature is governed by two bounding-limits (the effective bound and the matrix bound) depending on the time scale. A threshold time criterion is established in this research which is based on a heat penetration concept.
