Thin bamboo strips used for weaving piece is to enhancement layer design thickness, and the bamboo fiber nonwovens that the epoxy vinyl ester resin that winding has been formulated later is impregnated with are extremely
The design thickness of external protection coating completes the preparation of shell ontology by being heating and curing；
Above step carries out under conditions of ambient humidity is lower than 40%RH.
5. the preparation method of submarine pressure hull as claimed in claim 4, which is characterized in that described only to wind liner layer and portion
Divide shape between the first width segments of enhancement layer and the rest part with complete liner layer, enhancement layer and external protection coating of thickness
At faceted pebble, the faceted pebble is hackly inclined surface.
6. the preparation method of submarine pressure hull as claimed in claim 4, which is characterized in that the curing mode is from mold
Inside is outside and is inwardly heating and curing jointly from mold exterior, and is higher than from the outside solidification rate of mould inside from mould
The external inside solidification rate of tool；With regard to carrying out continuous heating solidification since preparing liner layer, until external protection coating is completed in preparation
And complete external protection coating solidification.
7. the preparation method of submarine pressure hull as claimed in claim 4, which is characterized in that the midship fore body shell ontology and midship
Stern shell ontology junction inner surface is bonded with multi-storey up-down and translation and is reinforced.
8. the preparation method of submarine pressure hull as claimed in claim 4, which is characterized in that the thin bamboo strips used for weaving piece width is 5mm-
20mm, with a thickness of 0.3mm-2mm.
9. the preparation method of submarine pressure hull as claimed in claim 4, which is characterized in that be added in the amino resins
