FUNCTIONAL FAILURE IN FILAMENT-WOUND COMPOSITE PIPE-A PARAMETRIC SENSITIVITY ANALYSIS APPROACH

摘要

The performance of filament-wound FRP composite is dependent on the properties of constituent materials (i.e. fiber, matrix and fiber-matrix interface) as well as on the manufacturing and design parameters (e.g. fiber lay-up, laminate stacking sequence, mandrel diameter, winding tension, winding time, fiber wet-out, etc.). In the first part of this work, we present a sensitivity analysis approach to ascertain the degree of influence of various mechanical and material design parameters on the structural failure of the composite laminated pipes. In the second part, sensitivity analysis results were used to design pipes with improved mechanical strength.
