FibaRoll PH Phenolic Prepreg- cheaper, safer processing of phenolic parts

FibaRoll PH, FTI’s phenolic prepreg (pre-impregnated) reinforced polymer, has been developed specifically to respond to demand for a cheaper, quicker and more efficient way to process lightweight phenolic parts. The product was engineered using a phenolic resin which is used in components specified for the London Underground because of their excellent fire and smoke properties. 

FibaRoll PH Phenolic Prepreg is delivered to the market on rolls as a tacky solid, which can be stored for three months or more; it is then cured by heat and pressure. Unlike other products on the market, when processed by compression moulding or autoclave FibaRoll PH is cured from the roll to its end shape in less than ten minutes. The phenolic prepreg has very low free formaldehyde, benefiting the operator with reduced emissions for an improved workspace environment.

Traditional phenolic prepregs are slow to cure, hard to store and require substantial post finishing. But new FibaRoll PH, developed specifically for the aerospace and rail industries, cures in under ten minutes at 130°C in a press, and there is no ramp up and cool down period and has great surface finish ready to paint. It can be stored in ambient conditions for three months.
