This article contains information on new duties of Centre for Composite Technologies (CCT) managers, implemented to increase their efficiency. Methods of quality improvement of aeronautical composite materials testing are presented. It was achieved by correct test plans definition, performing mechanical and physicochemical tests up to allowable composite generation. Several tests of this type are listed which are executed according to international standards of American Society for Testing and Materials (ASTM), including those in extreme temperatures. Effect of Lean Sigma and DMAIC (Define, Measure, Analyse, Improve, Control) implementation in the lab of CCT is shown. Results of bearing strength of quasi-isotropic laminate (carbon fibre and epoxy resin) with a bolt in different ambient conditions are presented. Moreover, the article discusses methodology of tension and shearing strength determination in the case of composite specimens diverging from others with application of statistical MNR method (Maximum Normed Residual). MNR coefficients are then compared with Critical Values.
