3mm 4mm 8mm thick Aramid core carbon plate

how to make carbon plate?why it's so strong comparing with metal material?0° Fibers maximize bending stiffness. Consider bending the the plate strip over your knee.45° Fibers maximize torsional stiffness. Typically plied together in an opposing manner, i.e. ±45°. Consider twisting a caron plate stripe like a vehicle's driveshaft.90° Fibers maximize crushing stiffness and generally assist in overallcarbon plate strength. Consider laying the carbon fiber strip on the ground and stepping on it.Honeycomb carbon fiber plate is formed by Aramid core or PIM core sandwiched  by top  layer of carbon fiber plate and bottom layer of carbon fiber plate. Specific modulus is 3 times of metal plate like Aluminium or stainless steel

Aramid core:heavy but strong not easy to process by CNC  also price higher than PIM ,Aluminium

PIM :light but not strong enough

birch wood core:light ,strong but flame retardant property not very good

Alumimium core :mostly are used for Pickle ball pad
