Quasi-isotropic refers to a layup of individual carbon fiber laminates such that the final composite material has approximately equal stiffness and strength properties in all directions. If only 0 and 90 degree carbon fiber layers are used, the laminate is cheaper to manufacture, but weak along the 45 degree diagonal. DragonPlate utilizes 45-degree diagonal laminate layers to improve quasi-isotropy. For the majority of typical applications, quasi-isotropic carbon fiber has superior performance.
