ANTI-IMPACT DEVICE OF DAMPING AND ENERGY-ABSORBING TYPE MADE FROM WEB-ENHANCED COMPOSITE MATERIAL

摘要

Disclosed is an anti-impact device of a damping and energy-absorbing type made from a web-enhanced composite material, comprising: an anti-impact unit (1) comprising a housing (2) and a filler material body (3) located inside the housing (2). The housing (2) is a solid housing comprised of a surface layer of composite material (4) or a sandwiched housing comprised of the surface layer of composite material (4) filled with a sandwiched material (5), and the sandwiched material (5). The filler material body (3) comprises a structural body of spatial grid (6) and an energy-consuming material (7), the structural body of spatial grid (6) being comprised of fibre webs (8) arranged in the housing (2) in a one-layer uni-directional, one-layer bi-directional, multi-layer uni-directional or multi-layer multi-directional way, and the energy-consuming material (7) is located between the fibre webs (8) and/or between the fibre webs (8) and the inner walls of the housing (2). The anti-impact device is low cost, has a high anti-impact performance, a long service life and is easy to assemble and replace.
