    I vote for honeycomb. Anything else is an unsafe compromise. ;^)

    My Take on Vacuum Bagging

    I stand corrected on the 7725 thickness. Old and obviously incorrect information. The flexural strength presented was just a comparison of properties for different fabric types in reality not theory. We see far too many people focus on what is "better" and "best" without them actually looking...

    My Take on Vacuum Bagging

    7725 .012 per layer 7781 .009 per layer 25% difference. Interesting fact. the actual length of the fiber normal to the plane of the laminates between crimps on 7725 and 7781 is very close (~.020" difference). Of course the crimps are larger on 7725 because of the thickness difference...

    My Take on Vacuum Bagging

    While I agree vacuum bagging can be a good thing, I think there are a couple of points most people miss. First and most importantly the ability to effectively use materials that would otherwise be difficult at best. Case in point, the use of 7781 vs 7725. They both have the approximately the...

    Personal Cruiser!

    I just went to the Aircraft deigns web site and looked at the description of Martin Hollmanns book "How to build composite aircraft". It still lists using Last-a-foam as a core material for aircraft production. It would seem he still considers this a reasonable method. HOW TO BUILD COMPOSITE...

    All good points for consideration. After reading your comments on the rest of the industry, I assume Martin Hollmann no longer considers Last-A-Foam a reasonable choice core material? He used it in his Nova project as documented in his book "How to build composite aircraft". I know the book is a...

    I think we are both saying about the same thing. The choice of materials must be driven by the total project requirements, including fabrication techniques available to the builder. Any design should utilize the materials selected taking into account not only the strengths but also the...

    In the interest of full disclosure, we sell Last-A- Foam. Now that I have admitted that, I can begin the healing steps on the road to complete recovery. On to the issue at hand. This is an interesting thread. IMHO it would seem what has been overlooked in this debate is this, could a competent...
