摘要:
Disclosed is a fiber reinforced thermosetting resin cylindrical shaped product manufacturing apparatus and method using a cylindrical forming die body having open axial ends and rotatable about its longitudinal axis. A cantilever beam body is positionable within the die body so as to extend along the die body longitudinal axis. The cantilever beam supports a suspension stand which is either movable or fixed. The suspension stand includes a reinforcing fiber feeding apparatus, a liquid thermosetting resin feeding apparatus and freely rotatable pressing rollers. A resin hardening agent feeding apparatus can also be included. While the die body is slowly rotating about its longitudinal axis, fiber reinforcing material is fed onto the die body and resin, possibly including a hardening agent, is fed thereto. This mixture is then pressed by the freely rotating rollers as either the suspension stand or the die body itself is axially moved.

A gel coating resin composition comprises (A) 10 to 45 parts by weight of an unsaturated polyester with an equivalent amount of unsaturated groups ranging from 140 to 330, (B) 15 to 60 parts by weight of a styrene monomer, and (C) 15 to 75 parts by weight of a polyfunctional (meth)acrylic monomer represented by the following general formula (I) and which has an equivalent amount of unsaturated groups ranging from 89 to 130: ##STR1## where at least four of the R's present are (meth)acryloxy groups, with the remainder being an organic group except (meth)acryloxy groups; and n is an integer of 1 to 5.
