Carbon fiber woven prepreg is a flexible pre-impregnated composite material made of carbon fiber weave fabrics (plain/twill weave) fully impregnated with medium-temperature epoxy resin.
With interlaced warp and weft fibers, it presents balanced mechanical properties in all directions and features excellent structural stability and surface conformability. Featuring uniform resin impregnation and stable surface tack, the material allows convenient room-temperature lay-up. After heat and pressure curing, it forms high-density, low-porosity and high-strength composite laminates, serving as a core base material for lightweight structural manufacturing..
