Re: Resin volume placed on foam

Frankenbird Vern
 

 This is the idea with caul sheets, which are made of dense high temp resistant rubber and then the parts are made in the autoclave where pressure (can easily exceed theoretical 15 psi permitted by vacuum) is equally applied during the cure. The pre-preg cure is accelerated and the temps taken right up to the heat saturation point so the structure will withstand higher ramp temps in Arizona for instance. 

 No post cure required as is done on tool-less composite with wet resin layup. The speed of the transition within the autoclave from a cold sticky pre-preg to a runny resin mix is just as critical as the stipple and squeegee process. Higher pressures also bring into the picture "core crush" problems which solid foams are not prone to. There are effective methods to prevent this problem (which for some reason Nordam had no idea about and they refused to listen to Contractor engineering folks that already solved this at other factory settings like at for instance, Raytheon!!)

 The short of it is.. yes.. the sandbag method works and with rubber sheeting on top of the bagging beautiful contour parts within reason can be made. Your getting into a tooling condition tho... but it is very acceptable. Advantage of shot bagging or sand is there are no vacuum leaks to be concerned about. Bleeder cloth are still involved and that is usual because the layup cures to an excellent correct ratio. By careful preparation you'll end up with near perfect parts with zero risk of a leaky tape seal or pump failure at the worst possible time.

Just a thought.  Would it help to vacuum bag parts and then put sand or lead on top of the outside bagging material to use weight to press the resin and glass together tighter into the weave?  It would be messy and you would have to keep the mold from creeping but what does the group think and does any one have any experience to share about that?  Just thinking outside the box.

Here is a link to a YouTube video where Cozy Girrl Randi explains about how Cozy Girrls make composite parts, including mixing epoxy, mixing micro, using gloves, low pressure vacuum bagging, peel ply, sanding etc. The video was recorded at Sun-N-Fun 2019 and the beginning has a lot of noise from the air show but Randi has great tips. https://youtu.be/fmuDOWTr_3c

Myself “sprinting” and Jay “singing” might be a bit of a stretch!  But then I’ve never heard Jay sing so next field of dreams I can bring my guitar and maybe Accompany Jay!  Let all encourage Jay to sing something!
Send me a song so I can practice a bit!

Re: Resin volume placed on foam

Thickness as fabric loft in un-consolidated laminates.

A consolidated laminate with the same number of plies will be thinner than a contact layup. Because thickness of the laminate is a cube function the consolidated laminate will not be as stiff as the unconsolidated laminate.

Resin sitting on top of fiber does nothing for stiffness as the Modulus of elasticity for epoxy is 400 K compared to glass 2 M.

Thinner laminates buckle easier and put more load on the foam that is trying to keep the skin from buckling.

Took to the beautiful clear blue skies of western Colorado this morning for about 50 minutes of fun in my Q. The calm conditions made it very enjoyable, and with the OAT at 1 to 2 degrees C at altitude, my plane also enjoyed stretching its legs. I took the time pleasure of doing a number of tight turns and couple of lazy 8’s. People on the ground were no doubt thinking that the pilot was drunk, but the pilot (me) did not care. I made one low pass “option” at my home airport, and glancing down briefly at the AS strip on the EFIS, I thought I saw 190 mph IAS. I suspected I might be imagining things, but my EFIS data download shows 192 IAS and 206 TAS. I think that is the fastest my plane has been so far. Made a very nice landing, so it really topped off the fun. I spent the rest of the morning laying on my back rubbing my plane’s belly. I think it likes that. I thought I heard it purring. I agree with Kevin B. It is too much fun flying these little Q-beasts. If you are building and not yet flying, keep pushing along. You will finish it at some point and then the fun begins.

Here is a link to a YouTube video where Cozy Girrl Randi explains about how Cozy Girrls make composite parts, including mixing epoxy, mixing micro, using gloves, low pressure vacuum bagging, peel ply, sanding etc. The video was recorded at Sun-N-Fun 2019 and the beginning has a lot of noise from the air show but Randi has great tips. https://youtu.be/fmuDOWTr_3c

Flight report

Jay Scheevel
 

Took to the beautiful clear blue skies of western Colorado this morning for about 50 minutes of fun in my Q. The calm conditions made it very enjoyable, and with the OAT at 1 to 2 degrees C at altitude, my plane also enjoyed stretching its legs. I took the time pleasure of doing a number of tight turns and couple of lazy 8’s. People on the ground were no doubt thinking that the pilot was drunk, but the pilot (me) did not care. I made one low pass “option” at my home airport, and glancing down briefly at the AS strip on the EFIS, I thought I saw 190 mph IAS. I suspected I might be imagining things, but my EFIS data download shows 192 IAS and 206 TAS. I think that is the fastest my plane has been so far. Made a very nice landing, so it really topped off the fun. I spent the rest of the morning laying on my back rubbing my plane’s belly. I think it likes that. I thought I heard it purring. I agree with Kevin B. It is too much fun flying these little Q-beasts. If you are building and not yet flying, keep pushing along. You will finish it at some point and then the fun begins.

 

Cheers,

Jay Scheevel, Tri-Q2 N8WQ, 136 hours

Bruce,

Vacuum bags provide uniform pressure. Weights do not. 25” of mercury is about 10 lb/in sq or 1440 lbs per ft sq. By reducing the vacuum to 5” Hg (shop vac) it would be about 200 lb / ft sq.

You end up with thinner face sheets that may weigh less but the buckling resistance is less than hand laid laminates. Stiffness is a cube function of thickness.

That is essentially what the vacuum is doing. If you draw a full vacuum, it is like putting 15 pounds of weight on every square inch. Practically, a full vacuum is not possible, but even 2/3 vacuum would be 10 psi.

 

Cheers,

Jay
