Does anyone have hands on experience doing resin infusion of carbon fiber with a balsa end grain core. In my research on the methods, I find statements of vendors that indicate balsa end grain can be fabricated as a core between carbon fiber this way but at this time, actual evidence or instructions by someone experienced doing this still eludes me. Does anyone know anyone what has done it (successfully), or is it mere hyperbole by the vendors of the balsa core material? FYI, I have written to one notable vendor with no response. I have also done a patent search and with one notable exception there are no patents that shed light on the process of sealing the end grain. The referenced patent simply says But how to seal it and with what to seal it? And how much weight is added to the balsa when it is sealed? Is this all a secret?
Looking for replies with experience.... no theories or conjecture, please.

Thank you Lester. What have you created with End Grain Balsa? Have you seen any links to destructiuve testing of CF with balsa core? The question of need for strength is not the same for every product. While designing my special purpose UAV, I watch a lot of videos. And when a UAV crashes, they are often damaged or destroyed. Damaged or destroyed is not a good thing. So regardless of the weight, strength is paramount.
