The experimental variables were the volume fraction and nominal size of the reinforcement particles. The CMFs were investigated (micro)structurally and via compressive tests. The compressive properties of the CMFs outperformed the unreinforced CMFs. The compressive strength and plateau strength can be increased by 82 % and 68 %, respectively. A 35 % increment can be measured in structural stiffness, while a 75 % increase can be observed in energy absorption capacity. The best properties can be achieved by combining the 0.50 nominal size and 30 % reinforcement volume fraction in the matrix parameters. The compressive strength was found to be more sensitive to the size of the reinforcement than to its volume fraction. The plateau strength and energy absorption were primarily influenced by the volume fraction of the reinforcement, while structural stiffness was the least sensitive to the experimental parameters. Along with the detailed analyses of the compressive results, a theoretical model has been proposed to predict the compressive strength of reinforced CMFs. This analytical model can predict the average compressive strength of reinforced CMFs with a relative error of 10%. Depending on the particle volume fraction and size, the reinforced CMFs showed diffuse failure or failure by cleavage.

In this study, the surface characteristics of two widely used aerospace-grade composite systems—glass fiber-reinforced epoxy composites and carbon fiber-reinforced bismaleimide composites—were evaluated before and after plasma treatment. Two plasma modalities were investigated: atmospheric-pressure air plasma and low-pressure argon plasma. A comparative analysis of these treatment approaches is presented, offering a novel contribution to the existing body of knowledge on plasma-based surface modification. Surface characterization techniques included Atomic Force Microscopy (AFM) for topographical analysis, water contact angle measurements to assess surface wettability, surface roughness evaluations, and cross-cut adhesion tests. Plasma treatment increased surface energy by up to 40 %, significantly enhancing the coating adhesion. Surface roughness values as low as 15 nm were achieved, and under optimized conditions, both plasma treatments resulted in GT0-grade adhesion.
