It glues well with epoxy resin or resorcinol adhesive. Tissues are commonly embedded in epoxy or other plastic resin. RCC was a laminated composite material made from carbon fibres impregnated with a phenolic resin. Composite materials consist of layers of fibers embedded in a resin matrix. G-3 is a material made of glass fiber and phenolic resin. Another substrate material is cotton paper impregnated with phenolic resin, often tan or brown. This heat shield was composed of phenolic formaldehyde resin. Nafion can be produced as both a powder resin and a copolymer. It consisted of two aluminum sheets separated by a honeycomb structure made of phenolic resin. The strike face is ceramic with the backface formed of laminated fiber and resin materials. Continuous liquid interface production begins with a pool of liquid photopolymer resin. The cost is similar to composite resin. Some polymers are also sensitive to attack, including acetal resin and polybutene. Spunlaid is bonded by either resin or thermally. The spider is usually made of a corrugated fabric disk, impregnated with a stiffening resin.
