Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets

Martyn Douglas Wakeman

Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...

Consolidation of net-shape random fiber thermoplastic composite preforms

Véronique Michaud, Patrick Blanchard, Martyn Douglas Wakeman, Simon Jespersen

A novel thermoplastic composite preforming process has been developed. This thermoplastic programmable powdered preforming process (TP-P4) uses commingled glass and polypropylene yarns, which are chopped to a desired length and deposited onto a vacuum scre ...

Polypropylene/montmorillonite (iPP/MMT) has been investigated as an alternative to isotactic polypropylene (iPP) as a matrix for glass mat thermoplastic (GMT) composites. The melt viscosity increased significantly on MMT addition, but iPP/5.9wt% MMT-based ...

Flow Properties of Tailored Net-Shape Thermoplastic Composite Preforms

Véronique Michaud, Patrick Blanchard, Martyn Douglas Wakeman, Simon Jespersen

A novel thermoplastic programmable preforming process, TP-P4, has been used to manufacture preforms for non-isothermal compression molding. Commingled glass and polypropylene yarns are deposited by robot onto a vacuum screen, followed by a heat-setting ope ...

Film stacking impregnation model for a novel net-shape thermoplastic composite preforming process

Véronique Michaud, Martyn Douglas Wakeman, Simon Jespersen

An impregnation model has been developed to evaluate the infiltration phenomena that occur during a novel near net shape preforming method. This process comprises automated deposition of thermoplastic resin and unidirectional (UD) carbon fibres to a pre-pr ...

Hybrid glass fiber-reinforced thermoplastic nanocomposites

John Christopher Plummer, Martyn Douglas Wakeman, Chrystèle Houphouet-Boigny Favre

The feasibility of integrating thermoplastic isotactic polypropylene/ montmorillonite nanocomposite matrices into conventional fiber-reinforced composites has been investigated. Two basic processing routes were considered: long glass fiber (GF)-reinforced ...

2008

Using an integrated processing methodology, an injection or compression moulded thermoplastic structure can be locally reinforced, for example, with textile structures or uni-directional fibre tows. Netshape components can be produced with cycle times typi ...
