ease the process. One is buying an epoxy pump instead of measuring the amount of resin to hardener by hand. With the pump, it will give the correct ratio with great ease. Although the epoxy pump will cost upwards of $150, its well worth it. If youre using Vinylester, you cant use an epoxy pump because, of course, its only used for epoxy. To use Vinylester youll need one nasty little item, (Wanttaja 219) a hypodermic syringe that has a capacity of 15cc but you will not need the needle. The syringe needs to have one-tenth cc increments marked. Another tool that is needed are sharp scissors or a rotary blade cutter. One of these are needed because you will need to cut reinforcing fabric. For some of the reinforcing fibers you need diamond coated scissors! Now youre ready to think about your lay up schedule. A layup schedule is a description of the number of layers of reinforcement and the direction of the fibers. The number of layers and fiber direction determines the strength of the composite. Most people cut a piece of material to the right size and lay it in the mold, then saturate the cut piece with the choice of resin. Preperation greatly affects the quality of the final product. (Wanttaja 232). When you are working with resin you need a warm room. This is for several reasons. One reason is because the resin cures faster in a warm room; the resin flows into the fibers quickly. This is good. You need to make six decision to make the composite for the frame:1) Fabric, you need to decide on what fabric you will be using,Kevlar 49 or carbon fiber, or other.2) Resin, you need to know what resin you want, either epoxy or vinylester3) Bleeder cloth, which is used for removing excess resin.4) Breather batting , used to remove air and suck up excess resin.5) Vaccum bag which is a bag that will hold a vaccum for an extended period of time.6) Vaccum pump which pulls the vaccum which will draw all the excess...
