Abstract
The present invention relates to a process and assembly for preparing a dry thermoplastic prepreg comprising reinforcing fiber spread tow (2) and airborne or melt-borne discrete thermoplastic fibers (4).
Claims20
A process for preparing a dry thermoplastic prepreg comprising:
- (A) transferring reinforcing fibre spread tow continuously between the upstream end and the downstream end of an assembly;
- (B) depositing airborne or melt-borne discrete thermoplastic fibres onto the reinforcing fibre spread tow in a deposition zone between the upstream end and the downstream end of the assembly during step (A);
- and
- (C) capturing the dry thermoplastic prepreg at the downstream end of the assembly.

An assembly for preparing a dry thermoplastic prepreg comprising:
- a transfer mechanism for transferring reinforcing fibre spread tow continuously between the upstream end and the downstream end of the assembly;
- a deposition system for depositing airborne or melt-borne discrete thermoplastic fibres onto the reinforcing fibre spread tow in a deposition zone between the upstream end and the downstream end of the assembly;
- and
- a carrier for capturing the dry thermoplastic prepreg at the downstream end of the assembly.
