So after crashing one of the BMW 2012 GS Challenge bikes head first into a tree which totalled the headlight and instrument cluster I have been thinking about how I was glad I hadn't been skewered by the branch. Now I have the Forcefield chest armour (http://www.forcefieldbodyarmour.com/product/race-lite-chest-protector/2351) which is great for absorbing impact but not preventing penetration of sharp things. With that in mind I decided to make an over lay for the Forcefield which I could take on and off as required. Forcefield chest armour. First of all I created a template out of cardboard. I then cut out the cardboard and covered it with cling film (Sarin wrap) to prevent the epoxy resin sticking. I then bent the cardboard to the required shape to fit my chest and used tape to ensure it kept its shape. I then cut out three layers of bi-axial 440 g/sqm e-glass. I then layered it up with SP Systems 106 epoxy and once cured remove the mould. I then cut the shape out using a Dremel and a tungsten carbide blade. I then attached velcro to the back. Image of it attached to the Forecefield. I then had my house mate stab me with a kitchen knife and punch me in the chest with some motorbike gloves. It all worked perfectly so I decided to create a final version out of carbon. The e-glass version weighed about 280 grams and cost around 4 UK pounds in materials. As the weather was cold here I had problems with the epoxy curing nicely and I ended up with many dry spots and air bubbles in the layup. I will avoid this in the final version.
