For instance, the tensile strength of the FRP is more dependent on the properties of the fibers, while shear strength is more influenced by the resin matrix properties. Due to their tailorable properties and unique characteristics (high strength, flexibility and stiffness), glass (GFs) and carbon (CFs) fibers are widely used in the production of advanced polymer matrix composites. Various continuous fabrics (braided, woven or stitched and knitted), strand mats and bulked or texturized rovings are used to obtain high strength in the transverse direction. Furthermore, the productivity of the AM process is mainly low because the layingbaggingdemolding cycles consume significant time and labor. Exposure of FRP to low temperatures may cause a ductile-to-brittle transition, which leads to the initiation of micro-cracks.
