Experimental Study of the Effect of Disorientation Angle on the Deformation of Carbon Composite Plates
The disorientation angle, a technological error in the manufacture of carbon composite materials, is the most important determinant of deviation of the obtained surface shape from the planned shape. Elimination of these defects results in additional time and financial costs. Therefore, this study examined the influence of the disorientation angle experimentally using carbon plastic (KMU-4l) composite plates measuring 300 × 300 mm with different basic structures such as 0/45/-45/90/90/-45/45/0; 0/0/60/-60/-60/60/0/0; 0/30/-30/90/90/-30/30/0. Plates were manufactured at a curing temperature of 175 °C and cooled to room temperature (23 °C). Fibers were pre-tensioned; the tension was removed after curing. The difference between the curing temperature and room temperature caused thermal stress and deformation in the material structure. This was examined together with the effect of the disorientation angle. Experimental results for composite plate hogging as a function of the disorientation angle and thermal load were analyzed for different structures.
