Abstract: As the existing WoT to use more closed tightly coupled architecture design principles, the system presents the shaft features that like the information silos. And the system infrastructure and service capacity is difficult to share and reuse. This architecture is suitable for large-scale industrial applications that their demands are clear. Third-party resources are difficult to be integrated into the system. All of the above are difficult to make large-scale application of WoT. This article polymerized common technologies of middleware. Thus it improved the ability of each heterogeneous device in the network, reduced the cost of application development, and improved the development efficiency.

Abstract: Based on the “ex-situ” toughening concept, thermoplastic nylon (PA) nonwoven fabric with high porosity was chosen as the toughening layer, and the interlaminar toughened composites were fabricated via RTM process. Compression strength after impact (CAI) properties were investigated as well as the toughening mechanism. The results indicated that there is no bicontinuous phase structures formed by reaction-induced phase decomposition and inversion. The PA nonwoven fabrics still kept the original structure in composites interlaminar, and formed a macroscopical bicontinuous structure with the matrix resin, which also showed remarkable toughening effect. The CAI value increased from 212MPa to 281MPa.
