Abstract
In this paper, the low-velocity impact properties of jute/ramie fiber reinforced composites were tested by drop weight method, and the effects of mixing ratio on impact properties and energy absorption of composites were also studied. A series of impact energies ranged from 2 to 20 J were applied on five composites including jute fibre reinforced composite, ramie fibre reinforcement composite and three hybrid composites. When the jute fiber reinforced composite material is mixed with the ramie fiber reinforced composite material, energy absorption capacity of ramie fibre reinforced composites were enhanced with hybridizing this two fibre fabric together. The damage area was assessed using an ultrasound c-scan instrument. The results show that the hybrid laminate with a volume fraction of ramie fiber of 55% has better impact energy absorption and impact resistance. It was found that hybridizating different fiber together can effectively solve the problem of insufficient rigidity of jute fiber reinforced composite material and high ramie of ramie fiber reinforced composite material.
