Abstract
The invention describes a method for making a composite panel and the product made by the method. The composite panel is made from a soft septum treated with a composition containing silane and an organic acid. The treated soft septum is adhesively bonded between two honeycomb panels, forming a sandwich of the septum between the two honeycomb panels.
Claims16
A method for making a composite panel having a septum sandwiched between a pair of honeycomb panels, the honeycomb panels comprising a pair of opposed sides and a plurality of contiguous cells with interior walls, the method comprising the steps of:
- (a) treating the septum with a composition comprising silane and an organic acid;
- (b) placing a honeycomb panel on each of the opposite sides of the treated septum with a heat curable adhesive between the panel and the treated septum;
- and
- (c) curing the adhesive.
A method for making a composite panel comprising the steps of:
- (a) treating a septum having first and second opposed sides with a liquid composition comprising silane and an organic acid;
- and
- (b) adhesively bonding a first honeycomb panel to the first side of the treated septum and a second honeycomb panel to the second side of the treated septum thereby forming a sandwich of the septum between the two honeycomb panels.
A composite panel comprising a silane treated septum sandwiched between two honeycomb panels with a cured adhesive adhering the septum and honeycomb panels together.
A composite panel comprising a septum treated with silane and organic acid, wherein the treated septum is sandwiched between two honeycomb panels with a cured adhesive adhering the septum and honeycomb panels together.
