Abstract

The invention relates to a method for sealing an edge of a plastic cellular sandwich board and an apparatus thereof. According to the invention, an edge sealing zone is arranged outside the contour of a product, in the edge sealing zone, a high-temperature part is inserted between an upper skin and a lower skin of the edge, honeycomb is removed through fusing, the upper skin and the lower skin are softened, and then the upper skin and the lower skin are turned to a center, so that edge sealing of the product is realized. According to the edge sealing method, the product edge is full and firm, the product edge intensity is enhanced, the problem of edge enclosing of a PPHC material is solved, and an application of the PPHC material on a spare wheel cover plate is promoted.

Description

technical field

[0001] The invention relates to the technical field of composite materials, in particular to an edge sealing method for a plastic honeycomb sandwich panel. Background technique

[0002] The honeycomb sandwich structure has the characteristics of light weight and high strength due to its hollow structure, and is widely used in automobile spare tire covers.

[0003] The common honeycomb sandwich spare tire cover has two materials, one is PHC board (abbreviation of Paper HoneyComb, polyurethane spraying process), the core material is honeycomb paper, the skin is glass fiber reinforced polyurethane foam, and the other is plastic honeycomb Sandwich panel, the skin is glass fiber reinforced plastic, and the core material is plastic honeycomb. Among the plastic honeycomb sandwich panels, the typical one is PP honeycomb sandwich panel, referred to as PPHC board (abbreviation of PolyPropylene HoneyComb, dry process), the core material is PP honeycomb, and the skin is...
