Abstract
The effect of cure temperature on mechanical properties of unidirectional ramie fiber reinforced composite was studied and the comparative research about mechanical properties of composites reinforced by plain ramie fiber, unidirectional ramie fiber and glass fiber was undertaken. Unobvious change of tensile and flexural properties was detected, when the epoxy resin 3233 was cured for 2h at 120°C, 140°C and 180°C. The ramie fiber reinforced composite had similar mechanical properties after cured for 2h at 120°C, and 140°C, however the composite after cured for 2h at 180°C had lower tensile strength and flexural strength and comparative modulus. The mechanical properties of unidirectional ramie fiber reinforced composite were much better than those of plain ramie fiber reinforced composite, such as that the compressive strength and compressive modulus of unidirectional ramie fiber reinforced composite uRa mie-3233-120 are 154.0 MPa and 35.6 GPa respectively, however the compressive strength and compressive modulus of plain ramie fiber reinforced composite fRamie-3233-120 are 95 MPa and 9.2 GPa respectively. The unidirectional glass fiber reinforced composite has much better strength, comparative to ramie fiber reinforced composite.
