Carbon fiber parts!!

[Chris TS-1438]

Ok. I know this isnt the workshop...but I feel as if this forum has soaked up all the workshop type threads too....now to the point..


Ok...I assume the carbon fiber triggers are carved from a small block of carbon...is this correct?


if so.. could we not mag emag frames/battery housings completely out of carbon or other strong composite, with metal framing..

by framing I mean..

a strip of metal in the rail to act as a grounding rail and to contain and connect the body and valve screws with metal.

metal threaded blocks installed where lowers are threaded (e.g. the batter field strip screw point)

Tell me the issues here....mind you I am fairly ignorant to the subtleties of Carbon fiber and other composites. The DM series are metal and exactly the sam as their little bro (the Proto) markers. Why not?

I don;t really know how regular AGD carbon fiber grip frames are made, but they are sturdy right? (see Mazda Miata-weight)

Certain parts can be made from a carbon composite material. It is very strong, but flexible, which is not good for rails. The rail is the backbone of the mag, which holds the sear assembly. Carbon fiber also has a poor wear rating, so it can't be used in the body where the bolt spring moves, plus it flexes so the body could potentially flex everytime a shot was fired.

How about other composites? I am familiar with the flex of carbon I have had it in baseball bats and golf club shafts. but I was under the impression that the flexibility depended on the polymer which it was mixed with.

Does and AGD stock C/F frame flex?

[athomas]

The AGD frame does flex a bit by itself, but is held pretty firm when it is fastened to the rail but the amount is insignificant for what it does. If it was to hold the sear in place, I don't know if it would be so insignificant. I can bend the AGD carbon fiber grip frame with my fingers. I can't do that with the aluminum frame.

The flexibility of carbon fiber products are ultimately dependent on the resin you use them in. The fiber adds strength to the resin. Most resins have some flex, but crack if too much force is applied. The carbon fiber by itself is very flexible, having almost no stiffness on its own, but possesses incredible tear resistance. Combining the two, you get slightly more flexibility than just the epoxy, but get the tear resistance of the fiber to provide strength.

Do carbon fiber tanks flex? Seems like if they are rigid enough to hold threads under 4.5k psi seems like a rail should be able to be made to be rigid enough. Maybe instead of just a rail, what about a unibody made out of CF?

[BiNumber3]

Tanks are aluminum wrapped with carbon fiber, so shouldnt really be able to flex.

Ahhh, didnt take that into consideration.

[PrimoRocker]

maybe having alum or steel plates to add that rigidity needed? Seems awefully expensive but would look cool.

You could also mill the hell out of a rail and then rap it in CF like they would with an air tank.

If its just the look you are going after, you could just have your aluminum parts hydro dipped. Pretty sure they make a CF pattern.

Actually, there's a number on the side that tells the hydro tester how much swelling is allowed during the test, so they do stretch a little.

I've always wondered if you could make a G10 rail. I don't know that it would be much lighter than a ULE rail of the same rigidity.

actually carbon molded parts would be perfect for the rail a very small aluminum "spine" would be needed but the flex you speak of is very dependent on the epoxy resin used.
