Problem 3 (15%, 5 each) Composite laminates are made from carbon fiber/epoxy prepreg. The laminates initially were flat and rectangular (one side is parallel to 0-degree direction) before the resin was cured. The resin shrinks when it cures. For the following layups, determine if the laminates after curing will be distorted besides shrinking from its original shape (flat, rectangular), and describe the distortions such as warping (out- of-plane deformation) and skewing (in-plane distortion), if any. You must explain how you reached the conclusion. Use drawings to illustrate. a. [30/60). After curing, the panel is (delete those not apply): flat, rectangular, warped, skewed Explain with drawing(s): b. [90/45/-45/0/0/-45/45/90] After curing the panel is (delete those not apply): flat, rectangular, warped, skewed. Explain with drawing(s): c.
