Abstract

Glass fibre reinforced resin masts are produced by (a) preparing an assembly by winding strands or strips of woven or nonwoven glass fibres onto a core which can be inflated and deflated, (b) placing this assembly in a vertical tubular mould, to leave an annular space between the assembly and the internal wall of the mould, (c) pouring a polyester or epoxy-resin into the mould to fill the annular space, (d) curing the structure within the mould, and (e) extracting the elongated structure from the mould and separating the core. Glass fibre reinforced resin structures such as masts, columns and posts produced rapidly and economically. The structures have good uniformity.
