Abstract
The heat resisting fiber-reinforced composite material of the invention is a heat-resisting fiber-reinforced composite material used for a product or a part that generates temperature distribution; wherein the thermal expansion coefficient at a portion corresponding to a medium to low temperature range is greater than the thermal expansion coefficient at a portion corresponding to a high temperature range, and the boundary between the portion corresponding to medium to low temperature range and the portion corresponding to the high temperature range is a transition region.
