Abstract

An apparatus useful in repairing molded thermoset FRP parts is disclosed having means for applying heat and pressure to a defect in the FRP containing a repair material while the FRP part is substantially rigidly held on a nest or support.

Claims

1. An apparatus useful for the repair of molded thermoset FRP parts comprising a vertically disposed stand, an arm attached to said stand for vertical movement on and horizontal movement about said stand, pressure applying means slidably mounted on said arm for horizontal movement on said arm, said pressure applying means containing a vertically movable piston connected to a rotatable and tiltable pressure pad for applying pressure to an FRP part containing a defect having a repair material, an adjustable nest for substantially rigidly supporting a molded thermoset FRP part to be repaired under pressure from said pressure applying means, and means to provide heat to said FRP part where said pressure applying means is applied under pressure to the repair area of said part on said nest.

2. An apparatus according to claim 1 where the pressure pad comprises a shape conforming pad containing disposed therein shape conforming material, containing electrical heating means conforming to the contour of said pad and containing an outer cover adjacent said electrical means conforming to the contour of said pad and of an an inert, non-adhesive material.

3. An apparatus according to claim 1 where the pressure pad comprises generally a rigid flat surface containing an outer pressure applying resilient member.
