View attachment 1715964163 Ok, decided to make molds for the front bumper brackets. There are high quality aluminum sets out there that are very nice, but I need them to look stock. With that in mind and not being an engineer or never having stayed in a Holiday Inn Express. I figured the original brackets are 3/8” thick and designed to be able to hold up the front of the car. Bumper jack car. Carbon Fiber is 5x as strong as steel…………….by weight! That factoid has to have been written by some Congressmen, what it really means is if you need a 6”x6” plate that can only weigh a pound, a carbon fiber one will be 5 times as strong ish! and all I want to know is how thick to make them!!! Two facts I used to decide, one from a composite company guy, you will be “pretty safe” if you make it the same thickness as the steel part. (Huh) I tend to over build things, but that seems a bit overkill, ok. Then the aluminum ones are .190. Split the difference .218 in two layers of 5.7 oz 2x2 twill and 9 layers of 12 oz reg weave. Probably thicker than absolutely necessary, but running over the bumper would be BAD! Plus they need to be thickish to look stock. Made the flanges out of flashing. $10 for 6”x10’.
