The usage of jute fibre reinforced composite materials is widespread in modern society. High strength, modulus, erosion resistance, and insulation are only a few of its outstanding qualities. The usage of jute fibre-reinforced epoxy composite in structural applications is extremely prevalent. Epoxy composites made from jute fibre are increasingly being used for ornamental purposes, with applications ranging from vehicle bodies to industrial furniture to household items. From the manufacturing sector to the automotive sector, laminated composite structures are ubiquitous. Structures such as buildings, bridges, car bodies, machines, household items, biomedical devices, aerospace, maritime vessels, and many other types of structures rely heavily on composite beams. To better understand the dynamic behaviour of composite beams made from jute fibre-reinforced composite materials with and without holes is the fundamental motivation of this research. Several material tests following ASTM (American Organization for Testing Materials) standards are used to evaluate the FRP composite beam's (solid's) mechanical qualities. The erosion properties of this composite are improved with the addition of graphite powder as a filler material. We observed that the hardness increases (12%) up to 10% graphite filler addition then it decreases. Flexural strength, decreases (−66%) as we increase filler addition from 0 to 15%. The tensile strength (55%), and impact strength (15%) both increase up to 15% filler content. The erosion rate increases with increasing impact velocity for all composites, except for zero-weight-percent-filler jute-fibre-reinforced epoxy composites. The quantity of filler loaded, and the erosion rate of composites is maximum at an impingement angle of 60°.
