Abstract

The invention relates to a lightweight FRP-octahedral lattice combined protection structure and a design method thereof. The protection structure comprises an FRP surface layer, the FRP surface layer comprises an FRP upper panel and an FRP lower panel, and an octahedral lattice core layer is clamped between the FRP upper panel and the FRP lower panel; the interior of the lattice core layer is hollow and has a good deformation energy absorption effect, the octahedral lattice structure is dominated by tensile deformation, the deformation bearing capacity is larger, the energy absorption effect is better, the octahedral lattice structure is provided with three symmetric planes perpendicular to one another and has the characteristic of three-dimensional isotropy, and by designing an orthogonal test and by means of finite element analysis software, the FRP-octahedral lattice combined protection structure can be optimally designed, the structure mass is reduced on the basis of meeting the protection grade, and the advantage of light weight is fully exerted; the defects that a traditional protection system is heavy and large in size can be overcome, transportation and construction are convenient, the protection performance is improved, and good application prospects are achieved in the aspects of military protection and civil buildings.

Description

technical field [0001] The invention relates to a lightweight FRP-octahedral lattice combination protection structure and a design method thereof, belonging to a protection structure in the field of composite materials. Background technique [0002] In order to resist the bullet shooting and impact of stray bullets in war, it is often necessary to build fortifications to protect the lives of combatants. The existing reinforced concrete protection system is heavy, inconvenient to construct and carry, and has poor mobility. conditions, and the performance of concrete is easily affected by temperature changes; the earth-filled protection system depends on the land resources in the combat area, and its application range is limited. Lightweight features. Contents of the invention [0003] The invention provides a light-weight FRP-octahedral lattice combination protection structure and a design method thereof, which solves the defects of the existing protection system in the ba...
