Abstract [en]

Shape distortions are generally considered influenced by several factors including thermal contraction, curing kinetics, fibre content, lay-up (balanced / unbalanced) and anomalies developed during manufacturing. In this work influences from forming on the shape distortion of a C-shaped composite spar with a recess area on one side is investigated. The forming influences considered are fibre angle deviation, inbuilt residual fibre compression (RF compression) and inbuilt residual fibre tension (RF tension). Abnormalities due to various stacking sequences and choice of lay-up process are especially focused upon.
