Textile or woven composite structures are an important material in many engineering applications. However, in many instances these structures are confined to those of thermoset matrices. The last decades or so saw the emergence of thermoplastic composites which exhibit several obvious advantages compared to those of thermoset. These include amongst others, easy processing, versatile end properties, especially damage tolerance, better working environment, etc. Morever, woven composites are always referred to those derived from fabrics, either preimpregnated or otherwise. However in the present study, a different approach in producing woven thermoplastic composite has been made. Namely, these woven thermoplastic composites were made by using the preimpregnated towpregs or prepregs, prepared usually in unidirectional tape form, instead of those derived from fabrics. The effect of different types of towpregs such as number of tows and matrices on the composite properties was examined. In short, the woven composite properties are clearly dependent on the towpregs properties. In addition, the advantages in handling, control and designing in attaining the desired composites properties were noted.
