Bolt Push Through in Composite Plates

This week I was doing background literature searches for bolt pull through strength in composite plates. I have done this a few times in the past looking for public domain reference strengths and must have missed this gem. NASA-TM-87603 contains test results and conclusions for testing of a 3/16in diameter composite huck fastener in a wide variety of laminates. The strength values in this report do look relatively high compared to my experience of testing pull through strengths in composite plates so I would be concerned by any low margins of safety that I generated using these figures.

Technical Library FAQs

Who are you? We are the engineers from Abbott Aerospace UK Ltd.

Why do You do this for free? A lot of the library material does not originate with us so, with good conscience, we cannot charge for that part of the library. There are issues with commercializing the material that we create, copy protection, customer support and pricing at the right level. By making everything available free of charge it lets us concentrate on content.

How is the library funded? The library is funded using revenue from the engineering service side of Abbott Aerospace UK Ltd., and by the donations of the people who find the library useful.

What should I do if I think I see a copyright violation in any of the library materials? Please contact us immediately and give us specific information about your concern

What should I do if I think I find an error in any of the library materials? Please let us know immediately

I would like to help the library by volunteering my time. How do I do that? At the present time we are unable to accept any offers of help. In the future we would like to work with a group of volunteer engineers. At this time we have not developed the digital infrastructure to make this possible. You can help by making a donation of any size.

I would like to help by donating materials I have collected or created. How do I do that? Let us know what you have and if it meets our criteria we will gladly accept it and give you a name credit if you choose.

What is the acceptance criteria for the library? For any material to be added to the library it must me the following criteria

It must not already be in the library
Where the material is not authored by the contributor it must be the demonstrated to be in the public domain or where the material is created by the contributor it must reference an available public domain source.
It must be either a Adobe PDF document, a Microsoft Excel spreadsheet or a Microsoft Excel add-in file. Other types of files can be considered.
