- Categories

- System
- Polypropylene (PP)
- Composition
- Polypropylene with 15% glass fibres
- Standard codes
- Reaction
- Processing
- Injection moulding
- Applications
- Short fibre reinforced thermoplastics are mouldable but the fibres confer greater toughness and stiffness upon them. This micrograph is a cross-section of the handle of a gas lighter.
- Sample preparation
- Technique
- Reflected light microscopy
- Length bar
- 400 μm
- Further information
- 15 vol % of short glass fibres are intimately mixed with the polypropylene matrix and injection moulded together. The fibre orientation reflects the flow of material into the mould. In this case, the fibres are well aligned in the outer layers of the moulding but more randomly aligned near the core.
