Abstract

A method for improving joint strength between a first and second member comprising the steps of: applying a sealant material including a matrix material at least partially encasing rigid components to the first and second members; joining the first and second members upon an application of force that is applied through the use of one or more fasteners; wherein a compressive force is applied to the exterior surface of both the first and second members by the one or more fasteners while the rigid components apply an internal tension force acting opposite of the compression force to the interior surface of both the first and second members proximate to the fastener to form a mechanical lock thereby reducing slippage and generally maintaining the joint in position.

First claim

The invention claimed is:

1. A structural lap joint comprising:
1) a first member including:
a. a first connection region including:
i. an internal surface,
ii. an external surface, and
iii. a free edge;

b. a main body portion extending from the first connection region;

2) a second member including:
a. a second connection region including:
i. an internal surface,
ii. an external surface, and
iii. a free edge;

b. a main body portion extending from the second…
