Mirror Background From the earliest recorded history, humans have been fascinated by reflections. Narcissus was supposedly bewitched by his own reflection in a pool of water, and magic powers are ascribed to mirrors in fairy tales.
Introduction There are four basic methods for laminating composite fabrics. This paper will discuss, in simple terms, these techniques, giving an overview of each method. These methods include overlay, vacuum bagging, pressure molds, and a few hybrid methods. Choice of fabrics Choosing a fabric type is mostly dependant on two factors — weave type and thickness.
Determining the weave type is based upon your aesthetic and conformability requirements. The most common fabric chosen for aesthetic applications is typically a 3K 2x2 twill for carbon fabric applications.
This fabric provides the most dramatic look of all weave types. For a more sophisticated look, a harness satin H8 or possibly harness satin H4 is sometimes used.
For maximum conformability, a harness satin fabric is the most flexible of all the fabric weaves. Which harness satin ex.
The next most flexible fabric is generally a twill weave note that a 4x4 twill will be more flexible than a 2x2. The least conforming fabric is a plain weave. It is no accident that the harness satin is the loosest of all weaves, while the plain weave is the tightest of all weaves.
Therefore you can generally conclude that the looser the fabric weave, the more conforming it will be to complex curves and the more easily it frays at the edgeswhile the tighter the fabric weave, the less conforming to complex curves, but it is likely to fray the least amount of all the weaves at the edges.
What thickness you need in a particular fabric is dependent on your application.
For cosmetic purposes using carbon fiber fabric, a 3K carbon is often an ideal choice. For structural applications, the most cost effective solution is to use the thickest possible fabric. Thicker fabrics are cheaper per pound than multiple layers of thinner fabrics, although thinner fabrics will generally conform better to complex curves than thicker fabrics.
The Overlay Method The overlay method is the simplest of all the laminating methods. Generally it involves finding an existing piece and sanding it lightly, then the composite fabric is laid over the top of this existing piece, and resin is applied.
Finishing such a piece using the overlay method generally involves one of two techniques.
The second option is to sand the piece smooth, then apply a final coat of resin or add a clear coat, typically of urethane for epoxy, or a polyester clear coat for a polyester based resin. Sanding into carbon fiber in order to smooth the surface is commonly not recommended since it can destroy the cosmetic appearance.
In order to provide a smooth outer layer without cutting into the carbon fiber outer layer, some add a final layer of fiberglass since all fiberglass turns clear when resin is added to it, and one can sand into the fiberglass to make a smooth surface without touching the underlying carbon material.
The main advantage of using the overlay technique is its simplicity.
The overlay method is commonly used when one custom piece needs to be made, or a small number of custom pieces need to be made. Vacuum Bagging Vacuum bagging is by far the most complex and expensive of all the methods, but usually results in the best final product after a well designed mold and your processes are well established.If the very thought of cutting glass makes you cringe, perhaps it’s because you remember a painful occasion when glass cut you.
Yet while caution is required, cutting a piece of glass—to, say. Imaging of inner structures: nowadays there is a request for noninvasive techniques in diagnostics, and hence invasive ones are restricted to presurgical examinations and interventional radiology; projection: reduction of dimensionality; 2D maximum intensity projection (MIP): a 3D image (x/y/z) projected into the x/y plane by assignign the maximum intensity that can be found along the z axis.
Thank you so much for these instructions and the idea. I was able to buy everything before my family Christmas party, used Christmas cards that I had saved from last year, and my children 6, 4, and 3 helped me make them.
