近年来，由高性能纤维制成的纺织结构在复合材料应用中的使用越来越重要。在纺织过程中，可以直接控制纤维的位置，并易于处理纤维。除了经济优势外，纺织技术还提供了基质和增强纤维的均匀分布。因此，织物预成型件被认为是复合材料结构的结构支柱。除了降低制造成本之外，纺织技术在改善复合材料的某些特性（如层间剪切和损伤容限）方面尤其重要。纺织工业拥有必要的技术，可以将高性能复丝纤维（如玻璃、芳纶和碳）编织成各种类型的预制件，这些纤维具有高拉伸强度、模量、耐化学品和耐热性。取决于织物预成形方法，预成形件的纤维取向和纤维体积分数的范围将变化，从而影响基质渗透和固结。作为纺织复合材料大规模生产的途径，生产速度、材料处理和材料设计灵活性是选择纺织增强产品的主要因素。这为纺织工业生产的新型半成品材料开辟了新的技术应用领域。本文详细讨论了用于热塑性复合材料的各种类型的混杂纱线和织物预成形方法。介绍并分析了不同混纤纱的制造方法、结构细节和性能。沿着讨论了用于这些混合纱线的表征方法以及不同工艺参数对所表征的性能的影响。介绍了纺织品预成型技术的各个领域的发展，包括机织、针织、编织、缝合和非织造布技术，并沿着讨论了这些预成型件的表征技术。沿着讨论了混杂纱线和织物预制件制造复合材料的技术，并详细讨论了这些结构在固结过程中的压实行为。混纤纱的结构和织物预型件的结构直接影响由其制成的复合材料的性能。对这方面的文献报道进行了详细的讨论。最后对热塑性复合材料的潜在应用领域和发展趋势进行了讨论和分析。
In the recent years, the use of textile structures made from high performance fibers is finding increasing importance in composites applications. In textile process, there is direct control over fiber placements and ease of handling of fibers. Besides economical advantages, textile technologies also provide homogenous distribution of matrix and reinforcing fiber. Thus textile performs are considered to be the structural backbone of composite structures. Textile technology is of particular importance in the context of improving certain properties of composites like inter-laminar shear and damage tolerance apart from reducing the cost of manufacturing. Textile industry has the necessary technology to weave high performance multifilament fibers such as glass, aramid and carbon, which have high tensile strength, modulus, and resistance to chemicals and heat into various types of preforms. Depending upon textile preforming method the range of fiber orientation and fiber volume fraction of preform will vary, subsequently affecting matrix infiltration and consolidation. As a route to mass production of textile composites, the production speed, material handling, and material design flexibility are major factors responsible for selection of textile reinforcement production. This opens a new field of technical applications with a new type of semi-finished material produced by textile industry. Various types of hybrid yarns for thermoplastic composites and textile preforming methods have been discussed in detail in this issue. Information on manufacturing methods, structural details and properties of different hybrid yarns are presented and critically analyzed. Characterization methods used for these hybrid yarns have been discussed along with the influence of different processing parameters on the properties being characterized. The developments in all areas of textile preforming including weaving, knitting, braiding, stitching and nonwovens techniques are presented and discussed along with the characterization techniques for these preforms. The techniques used for manufacturing composites using hybrid yarns and textile preforms are discussed along with the details on compaction behavior of these structures during consolidation process. The structure of hybrid yarns and the textile preforms have direct influence on the properties of the composite made from them. The reported literature in this aspect is discussed in detail. In the end, the potential application areas and their trends for thermoplastic composites are discussed and analyzed.
