Point of the Proposed Technology
By using in-situ polymerization thermoplastic resin, a prepreg for thermoplastic carbon fiber composite having a good tackiness and adrapability equivalent to a general-purpose thermoset prepreg can be produced. Therefore, the conventional equipment for thermoset prepregcan be used as it is. Also, since a molded product is thermoplastic, it can be secondarily processed by heating and also press forming.Furthermore, it has a strength/rigidity equivalent to that of thermoset carbon fiber composite. This improved prepreg has higher workability andbetter physical properties than that of conventional thermoplastic prepregs.
Effect(s)
・Equipment for thermoset prepreg can be used.
・Allowing mass production by press
・Molded product can be finely adjusted (customized).
・Allowing mass production by press
・Molded product can be finely adjusted (customized).
Conventional Technology
There is a problem that prepregs using common thermoplastic resin have notackiness and drapability and show poor lamination workability and metalmolding performance. In addition, there has been a challenge that moldedproducts have low physical properties because the impregnation performanceinto resin is low and the adhesive property at the interface with carbon fibersis also low.
