Fiber bundle, preparation method and application thereof, and fiber reinforced composite material
The invention belongs to the technical field of reinforcing materials, and particularly relates to a fiber bundle, a preparation method and application thereof and a fiber reinforced composite material. A plurality of monofilament fibers are combined together to form a fiber bundle, the surface of each fiber is provided with a surface additive to increase friction polymerization force among the fibers, and then the outer surface of the fiber bundle is coated with a binder coating. The fiber bundles are provided with independent fiber filaments, the fiber filaments are limited by surrounding fiber filaments mainly through friction instead of bonding, and therefore gradual but independent fibers are allowed to be broken or pulled out, the failure of the whole fiber bundles caused by the fact that the fiber filaments are broken or pulled out independently is delayed, and the effect of prolonging fiber bridging is achieved. The fiber bundle reinforced composite material has the advantages that the fiber bundle reinforced composite material is prevented from being pulled out too early, high bonding strength between the fiber bundle reinforced composite material and a composite base material can be fully utilized, high composite strength is achieved, fiber bundle breakage can be delayed, and the tensile properties (strength, ductility and toughness) of the fiber bundle reinforced composite material are improved.
本发明属于增强材料技术领域，具体涉及一种纤维束及其制备方法和应用、纤维增强复合材料。本发明将多根单丝纤维组合再一起形成纤维束，每根纤维丝表面具有表面助剂以增加纤维间的摩擦聚合力，然后在纤维束的外表面上涂覆粘结剂涂层。这些纤维束具有单独的纤维丝，纤维丝主要通过摩擦而不是粘结被周围的纤维丝限制，从而允许逐渐但独立的纤维断裂或拔出，进而延缓由于纤维丝单独断裂或拔出而导致的整体纤维束失效的发生，并实现延长纤维桥接的作用，避免过早的纤维拔出，并能够充分利用与复合基材之间的高粘结强度，实现高复合强度并能延缓纤维束断裂，提高纤维束增强复合材料的拉伸性能(强度、延展性和韧性)。
