CA 2435022
There is provided a duct and an associated preform and method. The duct is formed of a thermoplastic material and is lightweight, strong, flame and smoke resistant, and non-toxic. The duct is formed from a flat laminate and does not require a specialized, disposable mandrel for supporting conventional thermoset plies. Preferably, the duct is formed from a preform, which is cut according to the desired shape and size of the duct so that trimming after the duct has been formed is not required. Additionally, features such as holes and spud locations can be provided by cutting or marking the preform before forming the duct. Each duct can be formed of multiple articulated segments that are joined by connectors.
