摘要: Abstract The constant and variable amplitude fatigue strengths, the tensile compressive strengths of cfrp have been determined. Unnotched specimens carbon/HT fibre in an epoxy matrix were used form multi-ply 0 ± 45° 90° laminates. Results tests for stress ratios +0.1, −0.5, −1.0, −1.66 −5.0 are presented. Variable carried out using a flight-by-flight loading sequence typical wing root area fighter aircraft. Calculated life test results compared influence modifications examined with regard to high low load cycle ranges spectrum. behaviour composite material is that metals.
