Hi folks.
I work for a UK company producing prepreg superbike fairings and parts.
Does anyone else out there use prepreg as I’d like to share experiences, techniques and ideas with someone.
Feel free to drop me a message anytime.
Thanks.
No prepreg users out there at all?
JRomkes. He will drop by.
Which brands do you use? ACG?
Excellent, thanks mate.
Yeah we use ACG, currently using VTF261 (cosmetic) facing.
It’s really good.
Just looking to share techniques/ideas with people. 
I’ve used (ooa)prepregs in the past year. Really nice method for producing composites, and I hope to use it again in the future.(they have some fast curing series wich seem ideal on simple, large number productions). I’ve used the ACG bodypanelsystem(BPS240). VTF264 series, VTS, VTA, LTM, etc.
Did some tests with Delta and Lineo(flax fibre prepreg) too, but mainly ACG.
(I’m J. Romkes btw, my username on other forums…)
Hi mate, nice to meet you.
Yeah we use OOA prepregs and are currently the only company in the UK to produce Prepreg superbike fairings.
It’s a great job and we also make our own moulds and custom parts.
I’m currently making a Suzuki GSX-R 1000 for the Crescent Suzuki WSB team.
What sort of stuff have you made from prepreg? Do you work in the industry or do you just make stuff from home or a workshop?
Hi there I have used low tem,from Prf composites iam based in bournemouth,I make my own fairings,using wet lay,and infusion process I have made a couple of monocoque units for my own gsxr,air box.
Hi Shaneer, thanks for dropping by
That’s cool. How do you find resin infusion? Is it a bit hit and miss?
I’ve done a bit of wet lay and find it very hit and miss, it’s certainly becoming an out of date technology.
Prepreg is great, so much easier to use and you get great results the majority of the time.
It’s always good to share techniques and tips.
Hi, don’t use prepreg myself, but spoke to a surprising number of large companies last week that are now moving to RTM or similar because prepreg is too expensive.
Would be interested to know what your particular case is for using prepreg over other methods?
Hi Ryan.
The company I work for use prepreg as that is what the client wants.
We make bike kits for leading superbike teams, I am currently working on a Suzuki GSX-R 1000.
I personally find the finish and durability of prepreg is better than any other method. I’ve done wet lay and i find it very hit and miss, both in finish and durability.
Have you ever used prepreg at all?
I made Car parts, both structural and non-structural.

Yes your right,wet lay up and infusion can be a bit off hit and miss,I have had good results with wet lay up but I have to do post work on part,same for infusion I am making a rear spoiler at the moment,which is a two piece part,which when I bond together will need work,iam interested in pre preg have you got photo off your result’s.
I haven’t used prepreg before, I’m in R&D and more interested in the fibre/fabric than the resin so can’t really justify the large cost. Definitely prepreg is the best as far as mechanical properties are concerned and certainly better than wet lay. RTM and vacuum infusion however can give some pretty good finishes as well as not too shabby mech props! Obviously if it’s customer driven you have no choice though!
Is prepreg cheaper than infusion? Or is it a wash because you are substituting infusion materials for the prepreg?
I’ll take some pics today and hopefully get them posted later on tonight.
Prepreg is more expensive than infusion but the benefits are greater (at least in my experience)
It all depends on what the client is looking for.
We use prepreg for making superbike fairings as it generally provides lighter and stronger parts.
Do you have any specific problems that you wish to talk about with the parts that you are making? do you only make parts from prepreg? we make carbon parts in pre preg and Wet lay vac bagged.
Do you make parts other than motorcycle fairings?
Hi mate. I don’t have any issues as such. I just find it interesting to talk about techniques and tips.
I had a few issues in the past regarding dryness on parts but have since ironed those issues out.
We currently are producing motorcycle kits but are always looking to expand.
I’m also currently in the middle of making a mould of a PS3 lid to make a lid from carbon.
I mostly use pre preg yeah, I have had the odd use of wet lay but not much.
