The hole of through hole alignment；The core filled composite material is connected with the steel plate.
Further, the core filled composite material passes through epoxy construction gemel connection with the steel plate.
Further, the pultrusion bar is vertically fixed on the outside of the steel bushing by using instant drying adhesive.
Further, described steel bushing one end is sealed using adhesive tape.
Further, the pultrusion bar is fiberglass pultrusion bar.
Further, the epoxy structural rubber fills up the through hole.
Further, the steel plate is fixed by installation bolt nut.
The method of processing and implementation said structure comprises the following steps：
1) corresponding through hole is got on core filled composite material；
2) fiberglass pultrusion bar is vertically fixed using instant drying adhesive outside steel bushing, and composite wood is filled up using epoxy structural rubber
Through hole on material；
3) one end of steel bushing is sealed with adhesive tape, the steel bushing of the glass pultrusion bar glued is filled in composite through hole,
After steel bushing in place after, by pre-production it is good offer corresponding aperture steel plate align composite through hole, applied with epoxy glue
Composite and steel plate joint face are covered, installation bolt nut is unified to fix steel plate using torsion；
4) be heating and curing overall structure, treats after the completion of epoxy construction adhesive curing, removes all bolt and nuts, and use drill bit
Foreign matter on steel bushing endoporus and cleaning steel plate is cleared up, that is, obtains core filled composite material metal carry fixing point structure.
Due to using above technical scheme, beneficial effects of the present invention include：
1) present invention efficiently solves the structure of modification of large-scale carry metal parts on core filled composite material, and the present invention is provided
Core filled composite material on metal carry fixing point structure it is reliable and easy for installation.
2) method of processing and implementation structure of the present invention is simple and reliable, and user satisfaction is high.
3) metal carry fixing point structure is successfully used for certain large-scale transnational enterprise on the core filled composite material that the present invention is provided
The heater of industry latest model deicing version wind power generation blade is fixed.
Brief description of the drawings
The schematic diagram of metal carry fixing point structure on the core filled composite material that Fig. 1 provides for the present invention.Reference is said
It is bright
