Are 100% Green Composites and Green Thermoplastics the New Materials for the Future?

Table 3

Average physical and mechanical performances of different composites.

Composite	Density	Elastic modulus (Stretching) (MPa)
Synthetic thermoplastic + 30% glass fibres	1.1–1.6	82–220
Moulding high pressure		4000–6000
Thermo setting Resin (polyester) + 30% glass fibres	1.4–2	80–400
Natural based thermoplastic + 20% flax fibres	1.2–1.4	500
