CF just doesn't tolerate imperfections in workmanship too well, so you have to go with the utmost reputable makers. Small errors can lead to major failures. Boeing tried to make a wing out of CF when they were competing for the JSF contract but they kept having problems when they put it under sonar and it revealed imperfections in the molding process. They've gotten better at it but it's all in the process.
