The occurrence of fibre crossover and undulation(FCU) is inherent of the filament windingproc ess. However, the study on the effect of FCU on the mechanical performance and failure of filament wound composite(FWC) structure were mainly experimental research. So in this paper, a macro-meso failure analysis model for FWC considering FCU is established based on Puck, Hashin failure criterion and Linde stiffness degradation model. The influence of fibre crossove r and undulation on the stiffness failure is calculated and analyzed. The numerical results show that the strain in FCU region is higher by about 1.07–1.13 times than it in laminate region, the FCU have a certain influence on the failure strength of filament wound composite and the failure position of FWC under axial tensile load and internal pressure is mainly located FCU region and the failure position under axial compressive load is related to the winding angle.

Axial Reinforcement

The relationship between the axial inserted yarns and the mechanical properties of the multi-angled filament wound pipes was studied by experimental investigation in this paper. Firstly, the glassfiber/epoxy pipes with different process parameters were fabricated on the specially-designed filament winding equipment under varying conditions. Then the specimens were made in terms of standard sizes and tested under axial tensile load and axial compressive load, respectively. Furthermore, the axial tensile strength and the axial compressive strength were obtained from the test data, which showed that the above two values of the specimens with the axial yarns were larger than that without the axial yarns. That is to say, the incorporation of the axial reinforcement was found to result in increased strength.

Axial Reinforcement

This paper studied the axial tensile properties of the multidirectional filament wound tubes (MFWT) both theoretically and experimentally. Based on the Classical Laminate Theory, the mechanical analysis model of the tubes was established and implemented by the program of Matlab language, from which the axial tensile strength was predicted. Then the specimens with different parameters were fabricated and tested under axial tensile load respectively. The theoretical model met the experimental results well. Furthermore, the test results, the stress-strain curve and the failure form were analyzed, which showed that the axial properties of the MFWT were obviously strengthened with the incorporation of the axial reinforcement.

Closed-form solutions from complementary strain energy are derived for the spring stiffnesses of mid-surface symmetric, filament-wound, composite circular rings under unidirectional loading. A three-dimensional finite element analysis (FEA) including the effects of transverse shear has also been applied to study the problem. Four > 45° and four > 75° E-glass/epoxy composite rings of odd numbers of covers were tested. Comparisons of the results obtained from the two methods with experimental data are made and the results are found to be in good agreement. The FEA prediction of stiffness is always higher than the theoretical result. The relationships between the spring stiffnesses and the winding angles and geometry of the filament-wound composite ring are considered and discussed.
