Fibre Reinforced Composites

03/04/2017 4:18 AM

Is there any modern mfg method to fabricate intricate shapes of fiber reinforced composites ? Moulding is not the best way, I think.

From what I have seen, vacuum molding seems to be the most common way. Maybe if you contact this site, or this site, they can answer your question.

Fine answer.

A glance at the at Production Technology for Fiber-Reinforced Composites is revealing. A mere very limited production "can be easily laid into shape by hand and cured with simple tools"

But anything approaching high production standards and the volumes at which chemically and structurally complex parts are produced at an industrial level makes automation an absolute necessity.

Automation means astronomical investment in sub zero storage of prepregs, manufacture of molds, NC controlled layup machines, vacuum bagging and autoclave for vacuum curing etc.

Moulding is the cheapest way.....but 3-D printing is gaining popularity....

Wonder why 3D-printing has two only be lain down vertically. Ok, well then, what if it was done on the space shuttle?

I think we can not use fibers in 3D printing. And what may be the best way instead?
