Increasing the Performance of a Composite Flange

Recently JNDC completed an interesting job regarding the redesign of a lamp post flange. The current flange was manufactured in steel or extremely heavy GRP and was causing problems associated with thermal mismatch as well as difficulty in assembly.

The flange, to be designed in composite, had to withstand a 50kNm moment load.

Using FEA a new lightweight flange was designed.
