Abstract: A method for classifying failures can determine consumer devices on-line as being repairable or not to be repaired. The method obtains a training set, the set including information as to total failure and information as to repairable failure. First key information in repairable failure and second key information in total failure are obtained. A first TF-IDF value of each first key information and a second TF-IDF value of each second key information are computed. A first feature bank is created based on the first TF-IDF value and a first threshold value, and a second feature bank is created based on the second TF-IDF value and a second threshold. Target failure is classified by the trained classifier. A failure classification is quickly achieved. An electronic device and a computer readable storage medium applying the method are also provided.

Abstract: The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m2, thereby realizing performance and cost designability of a composite material.
