Abstract
PURPOSE: To obtain the title resin material having improved dimensional accuracy, e.g. parallelism, etc., by wrapping resin impregnated continuous filament groups around a space formed from a resin impregnated fiber layer consisting of a mandrel of specific construction and flanges.
CONSTITUTION: The self-supporting curable resin impregnated fibrous material 1 is formed by hand lay-up method, etc. The material 1 is then attached to the inner surface of the flanges 2' and 2' of the mandrel 2 by an adhesive, if desired. The continuous filament groups 4 impregnated with a thermosetting resin are wrapped around the space 3 formed by the flanges while rotating the mandrel 2. The body thus obtained is hot-cured, and the mandrel is diassembled to give the desired doughnut-shaped FRP.
EFFECT: Improved mechanical strength.
