摘要
The invention comprises a vacuum moulding process for composite materials, where an integrated thermoplastic/fibre reinforcement mat (80) is employed, where the thermoplastic (8) may consist of woven fibres (88) together with reinforcement fibre, e.g. glass fibre (87). In this way the need for injecting thermoplastic or tempering plastic in liquid form after vacuum suctioning of the reinforcement mat, is replaced. The problems with uneven distribution of the thermoplastic (8) are therefore substantially reduced. The integrated thermoplastic/reinforcement mat (81) is placed in a mould (1) and covered with a release film (3) and a vacuum bag (2). The vacuum is applied both to the thermoplastic/reinforcement mat (5, 8, 81), as well as in between the release film (3) and the vacuum bag (2). The vacuum is then consolidated before the temperature is increased, until the thermoplastic fibres become liquid at a temperature of (Tp) and envelopes and binds the remaining integrated fibre mat (5).
