Laminate Sample #38: Prepreg Carbon with Reinforcing Structure

This one's kind of cheating! Laminate Sample #38 is the first to have a panel-and-structure kind of approach to the 300mm square. The base panel has two flanges - each reinforced with unidirectional material. Spanning the flanges, tow omega-channel type stringers support the panel. The are bonded to the panel with toughened epoxy. This sample includes machining a separate mold for the stringers on my little Tormach - and some upstands placed on the panel tool to form the flanges. We have debulking and cooking and applying process materials. Bonding and masking and quick and dirty adhesive application. Lots of details - and lots of corners cut! Material is Gurit HEC300 and RC200 with SE84LV pre-preg. Adhesive is Proset. Have a look at this article at Explore Composites! on Laminating with Pre-pregs: https://explorecomposites.com/article...
