Some of the new plastics work pretty well like UHMWPE and others. They have been using this stuff on rally cars for years. It takes a lot of punishment if designed correctly. Its also pretty slippery and the overall weight is pretty low.
There is no impact resistant plastic capable of withstanding 21G penetration loads. Not at any price.
Then there is aluminum. This can also be used to make some killer skidplates that are not nearly as heavy.
Aluminum is not as strong as steel. The strength of materials is governed by the modulus of elasticity of the material being evaluated. Aluminum has 1/3 the strength of steel in the same thickness. The weight of aluminum is also 1/3 that of steel, for that same given thickness. To get the same strength in the materials, you need 3X the amount of aluminum to get the same strength of steel, at 1.75x the price per pound of steel. Basic engineering practice.
I think far too many people use too heavy a material for most skidplates. If designed and built properly I rarely see the need to use anything more than 1/8" steel. Build smarter not just with bulk. Keeping your vehicle light is going to buy you a good margin of performance on and off road as well as with mileage.

p1michaud said:I'll second the Bud Built skid plates. Very heavy, but worth the protection is worth peace of mind. Additionally, there is something to be said about a quality product. My skids bolted right up with no issues (OK, one nut was hard to put on due to the clearance between the existing cross membere and catalytic converter being tight).
Front skid = 55 lbs
Belly pan = 50 lbs
Cross member = 15 lbs
There is another thread about the Bud Built Skid Plates.

Yes I know but I was trying to give perspective if he wanted to build his own. AL might be that way to go depending on what you want it to do. Its always about what you want it to do.flyingwil said:But this is for a Dodge Ram... I do not think Bud makes any plates for Ram's

I still feel that more exotic materials can be used very effectively. If they couldn't you wouldn't see them in places like the Dakar rally, baja, about every WRC race, aluminum jet boats, fishing boats, competition level rock crawling, and many other applications.
