During this work, the materials (carbon fiber and matrix) were selected and cross ply [90/0]4s composite laminates were manufactured using filament winding. The laminates were inspected for damage, and samples prepared for testing. Quasi-static, mechanical fatigue and thermal fatigue tests were performed. Only a few matrix cracks were observed at a very high load and high number of cycles.
