一种连续长纤维增强热塑性树脂的成型方法及其成型设备
摘要：
本发明公开了一种连续长纤维增强热塑性树脂的成型方法及其成型设备。本发明的成型设备包括熔融浸渍模，熔融浸渍模包括浸渍模外体以及设在浸渍模外体中的热塑性树脂熔体夹缝流道、浸渍独立流道、连续长纤维入口通道和浸渍出口；热塑性树脂熔体夹缝流道设在上游端且与连续长纤维入口通道成一夹角，热塑性树脂熔体夹缝流道、连续长纤维入口通道均与浸渍独立流道连通，浸渍出口设在下游端且与浸渍独立流道末端连通；浸渍独立流道中还设有至少一组可自由旋转的张力辊。使用本发明的成型设备制备连续长纤维增强热塑性树脂，避免了纤维束之间的干扰和折损，保证了连续稳定生产，并提高了浸渍效果，从而获得性能优异的长纤维增强热塑性树脂。
摘要（英）：

The present invention discloses a molding method and molding equipment for a continuous fiber reinforced thermoplastic resin. The molding equipment of the present invention comprises a melting soakage mould. The melting soakage mould comprises a soakage mould outer body and a thermoplasticity resin fused mass crack flow passage, a soakage independent flow passage, a continuous fiber inlet passage and a soakage outlet which are arranged in the soakage mould outer body. The thermoplasticity resin fused mass crack flow passage is arranged on upstream end and forms an angle with the continuous fiber inlet passage. The thermoplasticity resin fused mass crack flow passage and the continuous fiber inlet passage are both communicated with the soakage independent flow passage. The soakage outlet is arranged on downstream end and is communicated with the end of the soakage independent flow passage. The soakage independent flow passage is also provided with at least one tension roller group which is capable to rotate freely. Using the molding equipment of the present invention for manufacturing continuous fiber reinforced thermoplastic resin avoids the interference and impairment between fiber bundles, guarantees the stable and continuous production and improves the dipping effect, so fiber reinforced thermoplastic resin with excellent performance can be obtained.
