Document Type and Number:
WIPO Patent Application WO/2009/020054
Kind Code:
A1
Abstract:
An FRP reinforced PVC pipe joint that realizes not only uniform dispersion of
reinforcing fiber and thermosetting resin but also satisfactory filling/reinforcement,
ensuring good appearance and resistance to breakage; and a process for manufacturing
the same. Use is made of a metal mold consisting of an upper die and a lower die and
having a cavity thereinside, and a bulk molding compound (BMC) or sheet molding
compound (SMC) for forming of an FRP layer is inserted in the lower die. In particular,
a preformed vinyl chloride resin pipe joint is fixed in the lower die, and the BMC
or SMC is inserted on the space superior to the vinyl chloride resin pipe joint.
Thereafter, the upper and lower dies are closed, and pressurized integral molding
