    Joining Composite Tubes

    Hi All, I'm looking to build a truss structure from fiberglass tubes. I haven't seen a lot on how to join pieces together. Most of the stuff I have seen is about extending a tube using an insert. In Solidworks, one can miter a joint to make them fit well together. My current thoughts is to do...

    Minimum Composite Thickness/Layup

    I'm suprised there isn't already a thread on this, but I couldn't find one specifically. Digging around in other threads I found a few suggestions for minimums but there is obviously a degree of personal preference. Here's what I've come up with: Glass (GRP): Billski mensions 3×7oz UNI...

    Wooden ribs and composite skin wings

    Hi, Newbie here! Having read the Rutan "Moldless" method of composite construction some time ago (1980's) and more recently, I have some questions. Sorry if this idea has been beaten to death before but I've read most of the threads and have not seen it. Could the wings be made as molded skins...

    Composite upper wing structure

    Hello, and thank you for viewing my question. Just a query I have regarding composites (has to be manufacturing using carbon/epoxy, 0/90 degree orientation) When designing a composite wing skin, to stiffen it, I propose to either have thicker geometry, insert a core (not sure which one) or...

    Composite airframe kits??

    I have been doing some research on different kits and am finding little with composite airframe and am wondering why that is. Is purely cost? Can someone give me some links to some kits that use composites? Thanks in advance.
