Composite Bridges – A comparison between moulded and pultruded bridges.

Resin Infusion of composite materials

We have published a technical paper to help clients and specifiers understand the significant differences in terms of installation, performance and long term maintenance of the different types of FRP bridge solutions that are available.

There are two generic types of FRP composite bridges and they have quite different performance characteristics and maintenance requirements, so it is important for clients to understand the differences at the procurement stage.

Moulded bridge decks are generally manufactured in a mould with dry fibres laid in specific orientations with a core material to produce a sandwich construction. They are usually moulded in one piece with no bonded or bolted connections.

Pultruded bridges use standard sections which are formed by pulling the fibres through a resin bath and mould. These sections are then bolted or bonded together to form the structure.
