A kind of flat shell fragment of thermoplastic carbon fiber prepared with ironing of the present invention is that a kind of carbon fibre fabric beam adds glass
The three-decker formed by extrusion and tension Flat belt of fabric, conventional Flat belt transverse strength can effectively be overcome not using this preparation method
The shortcomings that high, preferably solves the problems, such as following process, production efficiency is higher.Utilize thermoplastic carbon fiber polyurethane resin system
The flat shell fragment made, has the characteristics that waterproof, not salt spray resistance, burn into weatherability, can substitute existing stainless steel wiper completely
Lattice framing, there is very big market application foreground.
Patent of the present invention, the intermediate layer of the flat shell fragment of carbon fiber is glass fabric, and perisphere is continuous carbon fibre bundle,
Penetralia core is also continuous carbon fibre bundle, makes the surfacing of product smooth, internal to have Woven glass cloth to do framework material again, preferably
Ground solves the problems, such as the fluting of post-processing, it is therefore prevented that the generation of splitting phenomena.By the structure design of internal external carbon and
Ratio controls, and can effectively improve the elasticity of flat shell fragment, is controlled, can effectively improved by the structure design and ratio of Woven glass cloth
It horizontal mechanical performance, can also lower material cost, ultimately form the composite shell fragment with certain combination property.
