Well I’m interested in FRP…but I’m not sure if they sell it like that…or its a mixture of fiberglass and resin. I seen topics via Google about prepreg-fiberglass, but none about where to purchase in the US.
I want something that can FLEX like polyurethane. IF anything, I want to make urethane parts, but am not sure on how to go along on this.
So do people make FRP or polyurethane products themselves? If so…what flexible resin do they use…And for FRP or polyurethane products, would you also use fiberglass cloth? Thanks.
I’d say pretty much everybody on this forum makes FRP (composite) parts. There are many places that sell resin, various fiber types, and all the tools and equipment needed.
Not exactly sure what your question is. Urethane parts can be produced from FRP tooling.
I would like to produce body panels/parts for cars. I noticed “white” fiberglass products are really…really…bad. While the “black” FRP products seem to be a lot more superior.
How is the process different when making these types of products. And what is used to make FRP products?
I know that there are different types of resin… Polyester resin seems to shrink and expand. Epoxy is more superior, but it is uber stiff… I need something flexible and that will hold.
When people make FRP products, since it says “Fiberglass”…I assume that there is fiberglass cloth infused/layed with polyurethane resin - or a different type of resin?
First off, if you want something flexible, then it won’t support anything. Epoxy can be VERY flexible depending on which one, and which fiber. Even one layer of carbon fiber and fiberglass can be wrapped around a pencil and not break. The BLACK FPR stuff is probably carbon fiber, which is not fiberglass (unless it’s actually, black fiberglass, which is the same as white in terms of strength and material properties)
Let’s start with…what doyou want to make exactly. A door outside, or inside panel? Do you want to make one with your own shape and mold? Do you want it to shave weight off the stock door? Do you only want the looks? Fiberglass and carbon fiber will shave weight off a stock steel part if made right. If made wrong, it can be weaker, and just as heavy. A properly made carbon/epoxy door shell can shave 50% or more weight off, and be as strong. THere are TONS that go into designing something right. So start with small pieces, like a flat interior piece, or even overlaying a switch cover. You will learn about materials, resins, and procedures on this site, and in other sites. Check youtube for videos of infusing carbon fiber/fiberglass parts too!
if that actually is what Giggolo wants…good luck. The properties of continuous fiber composites would not allow a part like that, unless very thin, to flex like that, unless made with kevlar maybe. That bumper seems to be just plastic, or at least GF reinforced plastic, which can’t be done without SMC or a extruder and mold set.
Precisely, you can tell by the way she is dressed that she is just gagging to go and clean her house, so she has gone looking for black bags. :rolleyes:
