The work on infused ballistic armour is nearly complete. Composites have shown small, but significant weight efficiencies over metallic solutions. Coupled with the ease in which they can be moulded into structural vehicle shape they provide a viable future for ballistic materials. Thick composite laminate of up to 40mm have been produced by ACMC and ballistically tested by Alvis. The remaining work will focus establishing mechanical test data for future FEA.

This work continues to focus on the introduction of a broader range of composites fabrication techniques to the company. Traditionally a company known for its expertise in Resin Transfer Moulding, the time is now right for the exploitation of new and established composites manufacturing methods. Components other than the composite propeller, although a new design of smaller propeller is being developed, are being used to establish new in house technology.

Bioresorbable materials are a very significant development in the treatment of serious bone fractures. Having the clear advantage over metallic that subsequent surgery is not required to remove the material once healing and recovery has taken place. ACMC has played a key role for the client Smith & Nephew in producing and mechanically testing bioresorbable composite material, with demanding structural requirements. The material will be used for screws and splints.
