    I am carrying out some testing on polymer matrix compoiste sameples and need a way to attach the samples (dog bone shape) to the instron. The standard grips will not do.

    Have heard of drilling the samples at the end and there is a grips that can bolt through. Not sure bout this to be honest.

    Any body got any advice? Or does anyone have any experience with this type of testing that could help.

    Cheers

    Try roughening the sections of the samples in contact with the grips - are they slipping under load? Drilling the samples probably isn't a great idea as the dog bone shape is designed to give a well-defined gauge area.

    If this is a college project, talk to a lab technician about it as they've probably done similar work. Instron's site also has reports on testing pretty much anything, check it out.
