Mechanical, ballistic impact, and water absorption behavior of luffa/graphene reinforced epoxy composites

The mechanical, ballistic, and moisture intake properties of luffa fiber reinforced with graphene‐modified epoxy composites were experimentally investigated. The nanofiller graphene particles were modified with a matrix using the mechanical stirring process. The filler (graphene) of size 20 nm is modified with the matrix of different weight percentages 0, 1, 2, 3, and 4. The samples for various testings were prepared with different compositions...
