Abstract
Disclosed are co-continuous immiscible polymer blends of a polysulfone and a polyaryletherketone optionally reinforced with carbon fiber. A method of preparing such a co-continuous immiscible polymer blend of a polysulfone and a polyaryletherketone reinforced with a carbon fiber is also disclosed.
Claims17
A co-continuous immiscible polymer blend of a polysulfone in a polyaryletherketone matrix, wherein polysulfone fibers are distributed within the polyaryletherketone matrix.
A method of preparing a co-continuous immiscible polymer blend of a polysulfone in a polyaryletherketone matrix reinforced with carbon fiber, comprising the steps of:
- a) preparing a carbon fiber-reinforced polysulfone, containing a reinforcing amount of carbon micro-fiber, carbon nanofiber, or a mixture thereof;
- b) blending the carbon fiber-reinforced polysulfone with a polyaryletherketone, optionally reinforced with a reinforcing amount of carbon micro-fiber, carbon nanofiber, or a mixture thereof, in a blend ratio where the viscosity ratio of the components is equivalent to the composition ratio at constant processing temperature and shear rate, using mixing conditions that impart elongational flow and distributive mixing.
