摘要： Novel ultra-thin unidirectional pre-preg tapes are disclosed. They can be used to produce ultra-thin woven, bias, multiaxial, chopped-oriented etc. types of pre-pregs. These ultra-thin pre-pregs enable production of composite material products with well-controlled dimensional tolerances and smooth/even surfaces. Further, they render the production of composite material products relatively simpler, tidier, quicker, and economical. The obtained composite material products are relatively thinner, lighter, and mechanically higher-performing.
