Abstract
Abstract Fiber reinforced polymer composites (FRPC) made by 3D printing have attracted particular attention due to its ability to improve final components' properties by introducing fiber reinforcements. Fused Deposition Modeling (FDM) is one of the 3D printing processes by which fiber composite can be made. In the FDM process, molten thermoplastic deposited through a heated extrusion head with a small orifice in particular lay down pattern to create the 3D component. In the present study, the effect of fiber volume fraction on impact strength is investigated. MarkTwo FDM machine from MarkForged® is used to manufacture the composite specimens. Onyx is used as a polymer matrix material, while High Strength High Temperature (HSHT) fiberglass is used as a fiber reinforcement. It is observed that as the number of fiber layers increases, impact strength also increases. However, after a specific limit of adding the fiber layers, the increment rate in impact strength is limited.
