The collation of impact behaviour of titanium/carbon, aluminum/carbon and conventional carbon fibres laminates

摘要

Impact resistance is one of the basic properties of thin-walled coating structures that is of vast importance in the aerospace industry. Being able to absorb the energy of impact force, having resistance to puncture and being able to limit internal damage to the structure affect the continued load capacity of the component. Current aerospace designs utilize composite and hybrid materials. The work compares the low-velocity impact resistance of carbon fibres-reinforced polymer, aluminium carbon reinforced aluminium and hybrid titanium carbon laminates. In the assessment measurable, experimental and analytic evaluation criteria for the phenomenon of impact and the reaction of the material to this type of load, based on diverse physical foundations were utilized. It was demonstrated that a laminate based on titanium layers has at least two times higher impact resistance than an aluminium based laminate, and at least six times greater impact resistance than its conventional carbon-epoxy equivalent.
