Abstract

A method of manufacturing a coil support member in which a thermosetting or thermoplastic material is introduced into a mold cavity and hardened, wherein one or more components are positioned within the mold cavity during the manufacturing process before the thermosetting or thermoplastic material is introduced, the components are then embedded in the thermosetting or thermoplastic material and form an integral part of the coil support member, and one or more functional filler materials are added to the thermosetting or thermoplastic material to improve the thermal matching between the integral components and the thermosetting or thermoplastic material.

First claim

What is claimed is:

1. A method in which a thermosetting or thermoplastic material is introduced into a mould cavity and hardened to produce a coil support member, the method comprising:
positioning one or more components within the mould cavity before the thermosetting or thermoplastic material is introduced;
thermal matching the thermosetting or thermoplastic material with the one or more components including adding one or more functional filler materials to the thermosetting or thermoplastic material modifying a coefficient of thermal expansion of the thermosetting or thermoplastic material to better match with a coefficient of thermal expansion of the one or more components; and
defining the mould cavity so that the coil support member includes an external surface for supporting a coil wound about the coil support member.

2. The method according to claim 1 , wherein each of the one or more components is positioned within the mould cavity using one or more positioning members.

3. The method according to claim 2 , wherein a component and/or a positioning member is coated with a mould release agent before being positioned within the mould cavity.

4. The method according to claim 1 , wherein the coil support member is formed by a multi-stage manufacturing process in which each stage forms a layer or part of the coil support member.

5. The method according to claim 4 , wherein a different thermosetting or thermoplastic material and/or a different filler material, combination of filler materials or no filler material is used in different stages of the multi-stage manufacturing process.

6. The method according to claim 1 , further comprising winding a coil around the coil support member.

7. The method according to claim 1 , wherein a pre-formed coil or one or more blocks of superconducting material is positioned within the mould cavity before the thermosetting or thermoplastic material is introduced.

8. The method according to claim 1 , wherein one or more structural features of the coil support member are metalized in a post-production process.
