Another tip- don't buy from fiberglast. Most of what they sell is hugely overpriced and all of their private label stuff is just other products relabeled. For example, their system 3000 epoxy resin is just aeropoxy. $200 a gallon from fiberglast, $140 a gallon everywhere else. I buy fabrics for wet layup from soller composites.

 

I'm working on the bottom part of the trunk



And if anyone was wondering what I do for a living, well I worked for one of the biggest composite tooling company in the US (Marine Concepts/JRL Ventures). Now I make Carbon Fiber and Kevlar/fiberglass boats for Barker Boatworks

Vacuum Infusing A Fiberglass/Kevlar deck (from today)



Foam core about to go down over the Kevlar



Just done Carbon Hull

 

I made a hood with the headlight covers built into it (since the head lights no ,on get exist).

I used normal twill weave set (2x2?) top and bottom, 411 x 2 layers and then a 3mm core.

it came up very stiff, and I have track tested it several times.

I also only only did the top of the hood, so there is no bracing and no hinge mounting points.

 

Mmmmmm Barker. Beautiful boats. How'd the performance of the boat with the 7marine and a tower turn out?

Sorry for going off topic

 

83 or 85 MPH, not bad for a $130K engine lol

 

Subscribed. I've got a fiberglass 1/2 bumper front air dam I need to make a mold of so I can make me some more in carbon fiber. Been struggling with how exactly to make the mold and flanges. I'm thinking I need to separate the air dam from the rest of the front bumper but I worry that it will not be rigid enough if I do that. I think originally they may have taken a splash while the entire front bumper was mounted to the car. I also need to get all the vacuum bag stuff like bags, connectors, etc. for my vacuum pump. I'd also like to try my hand at vacuum infusion process at some point.

 

KYLE please come buy / take my roll of fiberglass matte to make your molds. It is clogging up my basement.

 

Oh, I never paid you for the kevlar. Im not in a rush, just let me know when you have the total with shipping and send me a PM.

 

Is it partly stock bumper with added air dam? maybe post #3 might inspire you

How much did it weigh?

 

I wanted to see if anyone has worked with Spread Tow Carbon fiber. I was woundering if I could use 2 layers of 160gr/m with a 1/4 honeycomb use for a trunk could be doable

It would be no heavier than 2kg.

 

Yes, sir! Absolutely! What flavor beer do you accept as payment? Maybe I can swing by sometime this weekend?

Yes it is stock urethane upper, fiberglass lower. Thank you for the link.

 

sent you some gmail.

 

This what I mostly work with 1800 18oz/yard 0,+45,-45 triaxial. It is a good structural for things like splitters, floors etc...



It is also used in the BMW i3 and i8. you can see it in the door sills

 

Wow that looks like great material.
I have a hobby ski press and would love to find some of that triax. Any idea what it runs per yard? And can you get 10 yard quantities?
PM me if you'd like to share your source; no one I deal with carries stitched 18oz carbon...

Man and that foam core for the boat... do you cnc mill the entire core?

Some random pics:

Urethane moat pour in the core

Here is a new radiator shroud for my aerocatch latch conversion. Its a 1/16th balsa core layed up wet with 5.7oz twill and envelope bagged with a stack on either side. I won't get a nice glossy surface this way but I will get maximum resin extraction:

 

I have been trying to come up with a plan to make a high quality hood without going the prepreg route- The materials cost on a prepreg hood is huge and you would need a 60" wide roll which is generally more expensive/harder to find than a 50" roll. I want to do wet layup and I don't want to do infusion. I also want to make the part as light as possible and extract the maximum of resin that I can out of the part.
My current plan looks like this:
Two layers of 5.9oz 2k twill vac bagged and cured. After curing, lay nomex honeycomb into the mold and one additional layer of carbon. Vac bag again. I think this will work well since I can get maximum resin extraction on each half of the part while still getting a glossy tool surface.

Suggestions for a resin? Carbon in the sun + engine bay heat means it needs to be higher temp than most RT cure epoxy. I have been using aeropoxy and am looking at pro-set. The hood is too big for my oven so I would need something I can RT cure and then do some crude post cure on using either a polycarbonate/wood box and the sun, or some light bulbs/heat gun setup. The pro-set Lam135/224 combination lists a TG of 223f with post cure but the work time on that is marginal for a part so big. I don't want to deal with handling vinylester or polyester resins in my attached garage.

 

The top is easy, paint it a solid color. Or if the rice factor is too strong, a uv protecting clear. Temp wise, insulate, gold foil is probably enough.
