    • In general, coated fibers, methods of bonding a coating to fibers, and composite materials prepared from coated fibers are provided. The coated fiber is created with a surface that is compatible with and bonds to the polymer resin used in composite materials. In another aspect, the coating may exhibit additional functionality, such as water repellency, fire resistance, or odor control. More specifically an atmospheric pressure plasma process is applied to the fibers to bond coating materials to the fiber surface and to cure the coating surrounding the fiber surface. Optionally, radiation is used in the process to cure the coating. Finally, composite materials and parts may be made from the coated fibers that exhibit high strength and improved mechanical properties over composites made with uncoated fibers. Alternatively, a natural fiber reinforced composite material is made from coated natural fibers that has improved mechanical properties and decreased water absorption.
    • 通常,提供涂覆纤维,将涂层粘合到纤维上的方法,以及由涂覆的纤维制备的复合材料。 涂覆的纤维产生与复合材料中使用的聚合物树脂相容并粘合的表面。 在另一方面,涂层可以表现出附加的功能,例如防水性,耐火性或气味控制。 更具体地,将大气压等离子体工艺施加到纤维上以将涂料粘合到纤维表面并固化纤维表面周围的涂层。 任选地,在该方法中使用辐射来固化涂层。 最后,复合材料和部件可以由涂覆的纤维制成,其表现出与未涂布的纤维制成的复合材料相比具有高强度和改善的机械性能。 或者,天然纤维增强复合材料由具有改善的机械性能和降低的吸水率的涂覆天然纤维制成。

    • A process to clean carbon fiber fabric of a pre-applied sizing, while simultaneously activating or preparing the fabric to receive a polymer resin is described. The cleaning process and chemistry combines an enzymatic cleaning solution with an oxidizing agent. The enzymatic solution strips the fibers of lubricants, surfactants, and other chemicals of the sizing which might otherwise interfere with interfacial properties and bonding of the fabric to the matrix resin. The inclusion of an oxidizing agent concurrently adds hydroxyl groups to the surface of the fabric allowing for the grafting of organic copolymers to the surface of the fabric, the copolymer being chosen based upon the desired polymer resin. This process provides a customized finished carbon fiber fabric to bond to a specific polymer resin, without interference resulting from an inadequate fiber sizing chemistry. In this way, a customizable finished fabric may be manufactured.
    • 描述了一种清洁预先施加的施胶剂的碳纤维织物的过程,同时激活或制备织物以接收聚合物树脂。 清洁过程和化学结合酶清洗溶液与氧化剂。 酶溶液将润滑剂,表面活性剂和其它化学品的纤维剥离,否则可能干扰织物与基体树脂的界面性能和粘结。 同时加入氧化剂同时向织物表面添加羟基,使有机共聚物接枝到织物的表面,共聚物根据所需的聚合物树脂选择。 该方法提供定制的成品碳纤维织物,以结合到特定的聚合物树脂,而不会由于纤维尺寸化学反应不足而产生干扰。 以这种方式,可以制造可定制的成品织物。
