Modern quality management techniques in product development of CFRP

Effective method for the amount of various factors. It consists of many different sizes and composition of the arrow. Figure in the middle is a thick arrow, said the results,[link widoczny dla zalogowanych], that is, a need to analyze the causes of quality characteristics, such as the layered CFRP products, poor plastic debonding and so on. Both sides of the arrow by the number of large arrow, that people, equipment, materials, methods,[link widoczny dla zalogowanych], and environmental factors in five areas. There are a number of arrows on both sides of each small arrows, respectively, the specific factors in this regard. If there are more specific factors, and then were more small arrow. Cause and effect diagram is characterized by fully reflect the causal impact of product quality, and structured, can be reflected from a particular impact because the results through what channels. HFB such products regularly appear in the thickening zone porosity, the causal diagram in Figure 5. Combination of historical data and process test, item by item analysis of the various causal factors, know the main reasons: �� soft mode deformation, fit is not ideal; �� larger humidity, process imperfections. [] Figure 5 products thickened area HFB cause stomata arranged in Figure 3.5 Pareto chart is to identify the main factors affecting product quality is an effective method. It is characterized by the quality of data in accordance with a variety of reasons affecting the quality of grouping, calculating of various factors impact on product quality, according to the size of the impact sequence, list mapping, in order to distinguish between primary and secondary factors to determine the focus of management . Such as product HXL lamination defects often appear around the corner, the arrangement shown in Figure 6. From the figure we can see, 52 flame retardant thermosetting resin in the rail transportation of September 2003 l8l26O circle 6 product defect Pareto HXL corner shop layered stack of products and processes are the main factors HXL corner stratification (often the total percentage of 0-80% as the main factor influencing factors.) In fact the quality and technology stack from the shop improve the standard two-pronged approach,[link widoczny dla zalogowanych], and achieved good results. ��7] in the CFRP product development, the timely application of modern quality management techniques can effectively control the quality of the development process, reduce scrap rates, reduce costs,[link widoczny dla zalogowanych], improve economic efficiency and reputation.
