A composite sandwich structure, comprising:
- a thermoplastic layer including a high-temperature thermoplastic polymer;
- a first thermoset layer disposed on the thermoplastic layer;
- a core positioned on the first thermoset layer, wherein the core includes a plurality of cells;
- and
- a second thermoset layer disposed on the core substantially opposite the first thermoset layer;
- wherein the composite sandwich structure has a heat release below 60 kW*min/m2.

A method of making a composite, the method comprising:
- forming a lay-up, including:
- at least one thermoplastic layer including a high-temperature thermoplastic polymer, the at least one thermoplastic layer being an outermost layer of the lay-up;
- a first thermoset layer;
- a second thermoset layer;
- and
- a core disposed between the first thermoset layer and the second thermoset layer, wherein the core includes a plurality of cells;
- and
- pressing the lay-up in a mold;
- and
- curing the lay-up to form a composite sandwich having a heat release below 60 kW*min/m2.
