Abstract
A polyaryletherketone polymeric material, for example polyetheretherketone and composite materials comprising said polymeric material are described. The polymeric material has a melt viscosity (MV) in the range 0.05 to 0.12 kNsm−2, preferably in the range 0.085 to 0.095 kNsm−2.
Claims41
A method of making a composite material which comprises a polymeric material of a type which includes:
- (a) phenyl moieties;
- (b) ketone moieties;
- and
- (c) ether moieties;
- and a filler means wherein said polymeric material has en MV in the range 0.07 to 0.11 kNsm−2 and wherein said filler means comprises a discontinuous fibrous filler or a non-fibrous filler, the method comprising:
- (i) selecting said polymeric material having an MV in the range 0.07 to 0.11 kNsm−2, wherein said polymeric material is of a type which includes:
- (a) phenyl moieties;
