This dufus decided on probably the worst composite material to use for a compressive load. Carbon fiber is very strong under high tensile load, it's used all the time for pressure vessels where the pressure is inside the vessel. Compressive loads, not nearly as much (as little as 10% the tensile strength of the same material). See https://www.sciencedirect.com/topics/materials-science/carbon-fiber-properties
