To address the challenge of low impact performance in continuous carbon fiber reinforced polyetheretherketone (CF / PEEK) composite plates caused by insufficient fiber/ matrix interfacial wettability and interlaminar porosity defects during compression molding, and to obtain a high-quality molding process, in this study, the influence of molding temperature, pressure, and cooling rate on the low-velocity impact performance of CF / PEEK was investigated. The interfacial wettability and post-impact interlaminar damage were analyzed by metallographic microscopy and ultrasonic C-scan characterization. The results indicate that within the studied process window, the capacity of composites to withstand impact loads and absorb impact energy decreases with increasing temperature, initially increases and then decreases with increasing pressure, and improves with higher cooling rates. Under the conditions of a molding temperature of 395 ℃, pressure of 0.6 MPa, and cooling rate of -22 ℃ / min, the resin wettability is significantly enhanced, the porosity is reduced, and the impact toughness is improved. Compared to the control group ( No.1:395 ℃ / 0.6 MPa / - 4 ℃ / min), this parameter combination increases the maximum impact load by 28.3% , achieves an energy absorption efficiency of 79.6% , and simultaneously demonstrates significantly improved interfacial wettability, reduced interlaminar porosity, and decreased area of post-impact delamination damage.
