I wonder if the APD and PD would feel better and transmit less shock if they actually used more dampening material such as kevlar or basalt throughout the frame instead of pulling this crap.
That's my hypothesis too; the GT layers are not the external plies in the carbon fibre layup.

An individual ply is typically 1mm thick, and any carbon fibre or graphite composite is usually made up of bunch of plies with the fibres oriented in different directions, with woven and unidirectional plies.

I'm not suggesting the OP do this but if you were to sand through the rcket you'd be able to see the different ply orientations, almost like rings on a tree.

An example with fibreglass;
