If you are talking about a sandwich panel (with a fiberglass and epoxy layup on each side of a foam core) then the foam core is definitely not there "just to form the part". The foam is critical to the stiffness of the part.Hey, total noob question about fiberglassing and foam. I was thinking of a more "automated" way to fabricate parts. I read a post somewhere that said the foam core is just used to "form" the part, not really an element of strength.
Do some more reading on the function of the cores. Two types of cores are common:I read a post somewhere that said the foam core is just used to "form" the part, not really an element of strength.
This is done to manufacture many pieces inside an airplane. My wings are "hollow" type as there are equipment bays and fuel storage in them. There are ribs at each end of each panel, to close out fuel tankage, to give places to anchor equipment, etc. There are also longitudenal structures to assist in tying upper and lower skins together and to close out the aft end of the wing. These many pieces were all made by laminating large sheets of foam with fiber-resin and vacuum bagged to minimize weight, then sawn out and bonded in with dry micro and fiber-resin tapes. Some places sell laminated sheets of foam reinforced with fiber-resin facesheets for this purpose.That said, could one take the BID and UNI fabric, do a layup without the foam core and then have a 3d router cut out multiple pieces out of a really big, say 4'x8' layup?
The mechanics of solid, plates, shells, and composites are all taught in engineering schools in departs with title like Mechanical Engineering and Aerospace Engineering. There are textbooks and other books out there on the topic. I have three engineering degrees, and can go from concepts to detailed calculations on these topics on a number of these topics. Engineering is real and allows us everything from space probes and satellites to CNC machine tools and additive manufacturing to our computers and cell phones. Have some respect for the effort that went in the training to do this stuff.Good grief, how did you all learn so much about this stuff?
Just yesterday, I chided a member briefly on how poorly formed inquiries rarely excite volunteers to put big significant effort into responses. This is such a case... Please consider thinking your way through the ideas you have and put in an amount of effort in the formulation of the inquiry that is similar to what you expect of the response.Hey another question. What if one could get a 5d milling machine (a really big one) to cut the entire "skeleton" out of foam as 4 quarters and get the longerons all formed from the same foam as the skin. Then you glass each piece with the different fabric like bid and uni in their prescribed directions and quantity, that should reduce build time considerably right?
This is another one of those queries where the effort in the question is so tiny no one has been inspired to answer. See post 28 above...-opinions about PARABEAM (PARAGLASS) in avia constructions ?
