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.
