Carbon Fiber Roving and Carbon Fiber Powder Comparison in Strenght for Engine Casing

[MustafaUmutSarac]

In Istanbul, there are two options for making fiber reinforced plastic making with carbon fiber or with carbon fiber powder.

Carbon fiber is ultra expensive and fragile in roving form.

Second option , kilograms of carbon fiber powder is abundant and ultra cheap.

I want to make a casing for engine with carbon fiber powder and epoxy mix and cast net net in cnc formed polystyrene molds which wetted with mold release agent.

Is that composite , strong as carbon roving ?

Or should I add glass roving also to composite ?

Do hot curing method requires special gases and pressures. How can I turn around this expensive technology ?

Not sure of the terminology , what do you mean by roving ?
By strong presumably you mean tensile strength ?
The tensile strength of carbon fibre is in the strength of the strand not the supporting resin.
The use of fillers can modify many of the resin composite properties such as density , hardness and flexibility but it is doubtful as to the strength being improved unless there is some chemical linking of the filler within the composite which is unlikely.

Thank you, abby. I mean with roving , textile. Thank you for your informative post.
