Composite material fuselage bulkhead suitable for solar unmanned aerial vehicle

The invention discloses a composite material fuselage bulkhead suitable for a solar unmanned aerial vehicle. The composite material fuselage bulkhead comprises a bulkhead interlayer, a high-modulus carbon fiber laying layer and a high-strength carbon fiber laying layer. The plane of the bulkhead is of a two-dimensional truss structure, the supporting columns are arranged on a force transmission path, and the force transmission efficiency is high; a carbon fiber-PMI foam sandwich structure is adopted, so that the structural stability is good, and the weight is light; an enveloping process is adopted for processing, PMI foam is not exposed on the periphery of the supporting column, and the structural integrity is good; the connecting piece is embedded in the PMI foam and is integrally processed and formed, so that the structural weight and the complexity are reduced; the high-modulus carbon fibers and the high-strength carbon fiber layers are combined, so that the strength of the bulkhead is guaranteed, and the
