In several fields of engineering the automation of the CFRP production chain is a major issue.
In fiber materials different deformation mechanisms exist.
From these very different materials, three material classes are mostly used by applicants.
For more complex deformations mode, like they exist e.g. in biaxial materials maybe a set of initial test has to be used, to identify the role of the two key modes within such materials.

Key Factor Extraction of Supply Chain Performance Based on Heterogeneous Selective Ensemble PCA Conghui Zhang 1, a, Nan Zhao 2, 3, b, Hongyu Shao3, c 1 Department of Management and Economics, Tianjin Electronic Information Vocational Technology College, Tianjin, China, 2College of Mechanical Engineering, Tianjin University of Technology and Education, Tianjin, China 3Tianjin Key Laboratory of Equipment Design and Manufacturing Technology, Tianjin University, Tianjin, China a13512264859@163.com, bnanzhao1982@163.com, ch4clo4@163.com Keywords: Supply chain performance, Key factors, Selective ensemble, PCA, Fuzzy integral Abstract.
The structure diagram of the algorithm is shown in Fig.1 Fig.1 Heterogeneous PCA Selective Ensemble Learning Algorithm Extracting Key Factor of Supply Chain Performance To approve the reliability of the algorithm, this thesis analyzes the time performance data of supply chain for C Company and extracts its key influencing factors.
The indicators of time performance include the cycle of raw material purchase（A）, average manufacturing cycle（B）, average distribution time（C）, financial decision time (D), time of purchase plan formation （E）and time of production schedule formation （F）.
And the final computed result is shown in Fig.2 Fig.2 Key Factors of Supply Chain Time Performance According to the figure, it is clearly seen that the key factors of supply chain time performance at C Company in 2007 were average manufacturing cycle and main raw material purchase cycle, whose key degree is higher than others, among which the influence of average manufacturing cycle is much higher than other factors, so it is the key object which needs to be monitored in the supply chain.
In order to prove the effectiveness of the algorithm, this thesis adopts K-means cluster to analyze the six indicators of time perforce A~F as well as the original data set of key factors obtained by selective ensemble learning, i.e., the original data set of main raw material purchase cycle （A）, average manufacturing cycle （B）and time of production schedule formation （F）.

The use of natural fibers turns engineering work more sustainable, since they are renewable, biodegradable, energy efficient and non-toxic raw materials.
These materials are widely used in numerous engineering projects such as the construction of embankments, roads, airports, reservoirs, canals, embankments and coastal protection works [1].
Synthetic fibers are currently the most used in geotextiles for civil engineering where the physical and chemical properties and durability are key requirements of the applications.
