A laminated metal fiber composite is a material made up of metal laminates interspersed with polymeric fiber-reinforced composites, this type of material has several advantages when compared to traditional composite materials or metallic materials, such as reduced specific mass, less water absorption and better mechanical properties such as mechanical strength, impact and flame resistance. Because of this fact, this material has gained more and more visibility and has been applied mainly to structural composition in the aeronautical industry. This work aimed to process the laminated metal aluminum fiber / PEEK / glass fiber, in addition to analyzing the influence, from the contact angle test, of 3 types of surface treatments on aluminum, mechanical abrasion, chemical pickling and phosphoric anodization, in their final properties from mechanical shear tests, CST, ILSS and Iosipescu, and fracture mechanics, ENF. The results analysis makes it possible to understand that the use of PEEK powder was a point of interference in the results, as well as the surface treatment of aluminum, from the results it is possible to observe a great reduction in the contact angle with the anodizing treatment. The performance of mechanical tests was possible only with the material made up with phosphoric anodized aluminum. The values obtained for shear strength and fracture toughness are lower than similar materials with thermoset matrices, which made the substitution of the matrix by PEEK not advantageous in this work.
