Fiberglass Hand Lay up Part
Introduction:
On this page, we will take a look at a sample layup (using a particular fiberglass hand lay-up technique) and how I have chosen to perform the work required by this step. The intention is that this page will have ample explanation, plenty of detailed illustrative photos, and background explanation so that it can be readily understood by those with very little fiberglass experience building ariplanes, doing repairs, or working on other projects.
While this example shows a specific structural reinforcement in the fuselage of the Cozy Mark IV airplane, these techniques certainly apply to many other composite construction projects using fiberglass or carbon fiber. If you are working on an airplane, boat, race car, or other project using fiberglass cloth or carbon fiber cloth then these techniques will apply. While this small instructable applies to structural and nonstructural aircraft, the techniques can be easily applied to construction or repair of many fiberglass or carbon fiber structures including fiberglass showers and hot tubs that use cloth (as opposed to mat) plus resin to form the composite. .
There is a slight difference in technique used when using polyester resins and fiberglass mat such as that used in boats, fiberglass shower stalls, and other projects. When using fiberglass mat on a project, the fiberglass mat is generally ripped by hand and applied with a different type of resin system that will dissolve the binder in the fiberglass mat. Fiberglass mat materials offer significantly lower strength and, along with other properties, are not suitable for airplane structural construction. Consider the information here to apply specifically for fiberglass applications using epoxy resin.
Where or how is this layup used?
In this example layup, we are going to add a fiberglass reinforcement to the F22 bulkhead and doubler where it attaches to the fuselage sides in Chapter 6 of the Cozy Mark IV aircraft. The instructions provided in the well-written Cozy plans assume that the builder understands how to perform this task by this point and summarizes the step in four sentences with an illustration included (worth a thousand words).
Just in case you are not building an airplane, In this example, we are adding a small layup of bi-directional fiberglass cloth to reinforce and strengthen a corner that was created earlier. So, we have a fiberglass structure that we have been working on using these same techniques, and we are adding a reinforcement fiberglass hand-layup to strengthen this fiberglass corner. This instructable / tutorial is intended to be not necessairly specific to airplane building.
The quote from the plans and illustrative drawing are from the The Cozy Mark IV FEBRUARY 2002 - THIRD EDITION Copyright 2002 by Co-Z Development Corp., Chapter 6, Page 2.

"There is a very important reinforcement to be added for the canard
attach hard points (Fig. 8). This is a 4-ply BID comer layup both
sides (right and left) on F-22 and the fuselage sides. Fibers are at
45 deg. and edges peel plied."
