Abstract
A composite structure having predetermined temperature/time profiles is made by combining in chemically separate yet intimate thermal relation a plurality of phase change mediums which change phase at differing temperatures in the overall range of the predetermined temperature/time profiles. Each of the phase change mediums changes phase at a different temperature in sequence for defining the thermal storage capacity of the structure and generally approximating the predetermined temperature/time profiles throughout the overall temperature range.
