Profile: Woolmer Forest Composites is a supplier of carbon fiber and fiber glass profiles. We stock a wide range of carbon fiber, glass fiber, and advanced composites. All our rods are manufactured with uni-directional carbon fibers along the length of the rod. Rods up to 5 mm in diameter are rods made with either epoxy resin or vinyl ester resin. All rods over 5 mm are made only with vinyl ester resin. Epoxy resin is a material which produces optimum mechanical properties.
