Hi FLD,

Thanks for the picture; it sound look like the 'bulging tow' has been caused by being flexed when not fully cured. It appears that some of the carbon tows have been able to break free of the matrix and then not bedded back down afterwards (which is not a huge surprise if the resin was mostly cured by then). Once it's properly cured you should not be able to do anything like this - we have samples that get mauled quite a bit as demonstration pieces and they hold up well. Thank you for the post and I look forward to hearing how the part performs in use.

All the best, Matt
