2804: VUR4: Legality of Composite Sheets
According to <VUR4> 1 teams are allowed to use sheet material in raw stock form. In the examples it provides plywood as an example which is a composite of materials. A: does this imply that all composite and processed materials are allowed as long as it is still in a form stated in <VUR4> B: are aluminium composite sheet allowed ( made of a polyester composite filling sandwiched between two aluminium skins), explistly this one here: https://nz.rs-online.com/web/p/metal-sheets/7781692
The linked material would be considered legal for use in the VEX U Robotics Competition, as it fits the definition of 'Sheet' in rule <VUR4> and is not prohibited by <VUR6>.
Composite materials CAN fit the requirements of <VUR4>, but not all composite materials will.
Teams should be careful not to use composite materials that may have safety risks, and should consider <VUR6>.
