Definitions
- a method of forming a rigid body with a curved surface comprising:
- the thickness of the reflective sheet and the honeycomb cell size are interdependent, and depend in turn on the required precision of the reflector surface.
- the reflective member might suitably be of the order of 0.8 mm in thickness when used with a base member having a honeycomb cell size of the order of 0.25 inch (6.35 mm).
- the thickness of the reflective member is likely to be in the range 0.5 to 2 mm.
- Aluminium or aluminium alloy is the preferred material for all of the components, but other materials, such as carbon fibre, could be used depending on the intended application of the reflector.
