본 발명은 열가소성 복합 화합물에서의 촙드 섬유의 용도에 관한 것이고, 특히 열가소성 불소중합체 화합물(fluoropolymer compound)에 관한 것이다. 불소중합체 매트릭스는 카복실 극성 작용기로 그래프팅된 열가소성 불소중합체, 예를 들면 Arkema로부터의 KYNAR ADX중합체를 함유한다. 촙드 섬유-그래프팅된 불소중합체 복합물은, 그래프팅된 카복실 불소중합체를 함유하지 않는 불소중합체 화합물에 비해 인장 및 굴곡 강도가 증가하였다. The invention relates to the use of chopped fibers in thermoplastic composite compounds, and in particular to thermoplastic fluoropolymer compounds. The fluoropolymer matrix contains thermoplastic fluoropolymers that have been grafted with a carboxylic polar functionality, such as KYNAR ADX® polymer from Arkema. The chopped fiber-grafted fluoropolymer composite has increased tensile and flexural strength compared to fluoropolymer compounds that contain no grafted carboxylic grafted fluoropolymer.
