Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to facilitate a clearer understanding of the present invention, but they do not limit the present invention.

[0033] Such as figure 1 Shown is the heat insulation structure of the filament winding engine, and the heat insulation layer of the head used in the heat insulation structure of the fiber winding engine in this embodiment includes a cover layer 5 and a bottom layer. The molding method is:

[0034] 1) Using separate pre-vulcanization molding to form a pre-vulcanized cover layer and a pre-vulcanized bottom layer:

[0035] Among them: the EPDM raw rubber sheet is vulcanized and molded into a pre-vulcanized cover layer, and the lower surface of the pre-vulcanized cover layer is located at the crack arrest point 4 to the direction where the diameter becomes larger (that is, the outer side) and there is a place reserved for EP...

Abstract

The invention discloses a seal head heat insulating layer forming method of a filament winding engine heat insulating structure. A cover layer and a bottom layer of a seal head heat insulating layer are firstly and independently formed in a vulcanization and compression manner and then overall formed in a vulcanization and compression manner, and the defect that the forming quality stability and consistency of manual SMT technology products are low is overcome. A release agent is sprayed or release cloth is pasted in the direction with the decreasing diameter at the crack arrest point, a proper tackiness agent is adopted in other lining layers, and the releasing effect of the cover layer and the bottom layer of the manufactured seal head heat insulating layer is good. In addition, when the seal head heat insulating layer is a rear seal head heat insulating layer, an EPDM heat insulating material wrapping structure is adopted in a T-1 anti-elation layer, and therefore the seal head heat insulating layer is isolated from a high-strength aluminum alloy connector. According to a provided integral forming mold, two sets of tools of the integral forming mold and a bottom layer forming mold can be achieved only by replacing an upper integral mold and an upper bottom layer mold, the structure is simple, and cost is low. Meanwhile, locating and mold releasing can be achieved well, and mold stripping of products is facilitated.

Description

technical field [0001] The invention belongs to the field of manufacturing a thermal insulation structure of a fiber-wound engine casing, and in particular relates to a method for forming a head heat-insulation layer of a fiber-wound engine thermal insulation structure and a mold thereof. Background technique [0002] The heat insulation layer of the filament wound engine shell is mainly composed of three parts: the front and rear head (ellipsoidal surface) heat insulation layer and the barrel section (cylindrical surface) heat insulation layer. The heat insulation layer of the front and rear heads includes high-strength aluminum alloy joints, bottom sheet (EPDM insulation material), cover layer (EPDM insulation material), delamination (bottom sheet and cover layer release material), or T -1 Anti-ablation layer (carbon fiber reinforced - nitrile / phenolic resin material). [0003] Among them: the main function of the high-strength aluminum alloy joint is to ensure that the h...
