Beschreibung
Zusammenfassung:	The invention provides a continuous fiber reinforced bio-based polyamide composite pipe and a preparation method thereof. The continuous fiber reinforced bio-based polyamide composite pipe sequentially comprises a lining layer, a reinforcing layer and an outer protective layer from inside to outside, wherein the raw materials of the lining layer, the reinforcing layer and the outer protective layer all contain bio-based polyamide. According to the composite pipe, the composite pipe reinforcing layer is sequentially wound outside the composite pipe lining layer, and then the composite pipe outer protection layer is wrapped outside the composite pipe lining layer, so that the manufactured composite pipe is resistant to high pressure, high temperature and low temperature and high in abrasion resistance and oil resistance. 本发明提供一种连续纤维增强生物基聚酰胺复合管及其制备方法。本发明的连续纤维增强生物基聚酰胺复合管由内至外依次包括内衬层、增强层和外保护层，所述内衬层、增强层和外保护层的原料均含有生物基聚酰胺。本发明中复合管通过在复合管内衬层外依次缠绕复合管增强层，再包覆复合管外保护层，制成的复合管耐高压、耐高低温，而且耐磨、耐油性强。
