Adhesive and impact strength of hybrid layered metal-polymer composites reinforced by basalt fiber

This work shows the possibility of obtaining hybrid layered metal-polymer composites based on low-carbon steel and aluminum alloys with interlayers basalt fiber reinforced thermoplastic polymer — polyetheretherketone by methods hot cold bonding use curing adhesives, respectively. The adhesive tear shear strength obtained two alternative impact steel-polymer alloy-polymer joints were evaluated. tests five-layered for bending samples “crack-arrester” type V-notch (with orientation notch line across composite layers) at temperatures −60, +20, +200°С carried out. analysis test results showed that have increased loads resistance to brittle fracture low climatic high working temperatures. Fractographic surface allowed determine proceeds through adhesive, cohesive, mixed mechanisms. Cohesive is initiated in layer nucleation crack growth along fiber-matrix interface, as well cracking fibers.
