 Posted: Thu Nov 14, 2019 6:46 am Post subject: Fiberglass instrument panel |
 |
|
The panels in our Long EZs (if built to plans) are made of fiberglass laminated on plywood. Very strong and has no problem supporting any instruments.
But, it is a lot thicker than aluminum panels, and may even be a bit heavier. Some have replaced the fiberglass/plywood panels with aluminum, leaving a narrow lip around the edges to mount the panel to.
I like this idea, and probably would have done it myself, but just wanted to follow the plans when I was at that point, and hadn't heard of this idea then. It would make it a lot easier to access the rear (forward!) connections of the instruments, as removing the panel and dropping it down would be a lot easier than trying to fish around in the min-hellhole between the instrument panel and the front fuselage.

1. Not as rigid(stiff) as aluminum so will require reinforcement to reduce localized bending. Ie, around openings where racks attach to the panel face.
2. holes that are made after fabrication break the glass fibers and are subject to tear out are cracking.
3. Requires a mold to make the panel thus additional time and effort to fabricate. (typically the panel needs to be removable to facilitate construction and maintenance).
Not impossible but not very practical unless there is some compelling requirement.

MAXI5005 is a spammer. Notice that he copied and pasted the original poster's question.
