Compared with equivalent metal structure composites have:
less weight
improved fatigue strength
greater corrosion resistance





Pre-preg
What are the benefits of Pre-preg Molding?
Pre-impregnated composite materials offer:
substantially reduced weight compared to metal
greater fatigue strength
improved corrosion resistance
simplified final assembly
Pre-preg is a proven, reliable process for the manufacture of both large and small composite components

What are the best applications for Pre-preg?
Pre-preg molding is ideal when there is a need to control only one side of a laminate. Sheet metal designs, therefore, can often be easily replaced with pre-preg composites.
Pre-preg composites are ideal:
when a honeycomb or other core material is required for light weight and high stiffness for large, complex geometry
the only limit is the size of the autoclave (GKN's largest is 15' by 55')
for simple geometry of any size
to take advantage of lower tooling costs for smaller production runs
