Freeform Composites: Design Guidance

STRUCTURAL QUALITIES: The mechanical properties of FRP can be tailored by controlling factors in the design of the material, but in general it has a very high strength to weight ratio. There are many other attributes to consider.

FINISHES: FRP materials can achieve virtually any form and finish. The surface texture of the product is a direct reflection of the surface of the mould, although secondary finishing of the product can also be undertaken.

DURABILITY: FRP materials have an established track record of durability in architectural and construction applications in demanding environments and are unlikely to be affected significantly during service by weathering.

SUSTAINABILITY: The embodied energy and CO₂ associated with FRP materials has often been shown to be lower than that of steel and aluminium, when both manufacturing and in-service performance are considered.

FIRE REGULATIONS: FRP materials can be manufactured to achieve an excellent surface spread of flames and fire barrier performance. They also typically have a thermoset polymer matrix so they do not melt in a fire.
