▎ 摘  要

NOVELTY - Honeycomb interlayer wave absorbing material comprises a first skin (1), a wave absorbing aramid fibre honeycomb core (2), a wave absorbing putty (3) and a second skin (4), the absorbing putty is filled in the absorbing aramid fibre honeycomb core hole lattice. The wave-absorbing putty comprises double-component epoxy resin, magnetic-loss absorbent and hollow glass micro-beads, where the bi-component epoxy resin comprises an epoxy resin and a curing agent. USE - Honeycomb interlayer wave absorbing material for improving inclined incident wave absorbing performance. ADVANTAGE - The honeycomb interlayer wave absorbing material can obviously improve the viability of the target. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing honeycomb interlayer wave absorbing material, which involves providing a mould and a wave-absorbing putty, paving prepreg on the mould, structure film and absorbing aramid honeycomb core, filling the absorbing putty in the hole lattice of the absorbing aramid fibre honeycomb core, continuously paving the structure film and the prepreg, pressing and curing to obtain honeycomb interlayer wave absorbing material for improving inclined incident wave absorbing performance. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of a honeycomb interlayer wave absorbing material for improving inclined incident wave absorbing performance.
