How can I increase the friction between the metal angle to the wooden board?

unnamed
Hey, for a project at school (with solidworks) , I am making an angle that holds two boards at an angle of ninety degrees under pressure.
(sketch Included)
How can I increase the friction between the metal angle to the wooden board?
what material should i use for it?
right now i only managed to make it that it can hold only wooden boards that are the same size, i need an idea how to change it so that it can hold too board that are different sizes?

and if you have any other helpful suggestions that would be wonderful

thanks

1. If the nut in the angle engaging the tightening screw in the angle is on a pivot so that it can swivel in an axis perpendicular to the plane of the angle it can tighten unequal boards.

2. place a thin rubber sheet between the board and the angle to increase friction. Alternatively, providing parallel serrations in the mating faces of the board and the angle perpendicular to the direction of potential movement will also help. You can even do both together.

thank you so much.
do you have an idea about what kind of material we should use?

That would depend on the strength and use (indoors, outdoors, adverse atmosphere and such)cast iron or cast aluminium seem workable.
