用颗粒和纤维增强天然橡胶 (NR)，使其能够用于高性能应用，例如公路自行车轮胎胎体。在这里，我们首次研究了丝绸纺织品作为天然橡胶增强材料的潜力，以生产全绿色、柔韧且增强的弹性复合材料。对各种材料性能进行了评估，并与类似的尼龙织物增强 NR 复合材料进行了比较。使用两种类型的天然橡胶：全天然橡胶和纯化天然橡胶。复合材料样品是通过将单层纺织品夹在 NR 层之间来制备的。天然橡胶/蚕丝复合材料比天然橡胶/尼龙复合材料表现出更高的静态和动态机械性能。此外，表面能测量和扫描电子显微镜照片表明，全天然橡胶复合材料中的丝绸纺织品的性能明显优于纯天然橡胶复合材料，因为前者具有更强的纤维/基体粘合性和更好的润湿性。这种生物基天然橡胶/丝绸复合材料可能会在软机器人和柔性充气管中找到有趣的应用。 (C) 2016 Elsevier Ltd. 保留所有权利。
The reinforcement of natural rubber (NR) with particles and fibres enables their use in even high performance applications, such as in road-racing bicycle tire casings. Here, for the first time, we examine the potential of silk textiles as reinforcements in NR to produce a fully-green, flexible yet strengthened elastomeric composite material. Various material properties were evaluated and compared with similar nylon textile reinforced NR composites. Two types of NR were used: whole and purified natural rubbers. The composite samples were prepared by sandwiching a single layer of textile between layers of NR. NR/silk composites exhibited higher static and dynamic mechanical properties than NR/nylon composites. In addition, silk textiles in whole NR composites performed significantly better than purified NR composites, due to stronger fibre/matrix adhesion and better wettability in the former, as indicated by surface energy measurements and scanning electron microscopy micrographs. Such bio-based natural rubber/silk composites might find interesting applications in soft robotics and as flexible, inflatable tubes. (C) 2016 Elsevier Ltd. All rights reserved.
