The material properties of the additive manufactured composite structures are usually done following international standards, that show some difference dimensionally. This study focuses on the impact-induced on the tensile properties of the 3D printed continuous carbon fiber reinforced composite part due to the standards applied for sample preparation. The specimens were fabricated by Markforged® Mark two 3D printing machine using carbon fiber as reinforcement and Onyx® as matrix material based on ASTM D638 and ASTM D3039-D3039M standards. The experimental results revealed that the specimens fabricated based on ASTM D638 showed a premature failure at the location where the straight gauge section of the specimen ends, and the curved transition regions begin due to stress concentration. The tests based on ASTM D3039-3039M standard showed better tensile strength and less stress concentration compared to ASTM D638. Fracture test with SEM reveals fiber breakage, debonding, and fiber pullout, which created cavities and voids between layers as the reasons for the tensile failure.

“…[8] The mechanism of fibertoughening composites mainly involved in fiber debonding and fiber bridging. [35] The fiber pull-out effect could absorb more impact energy, which was favorable for the improvement of toughness. [36] In this work, Figure 5A showed that with the increase of POE-g-MAH ratio in dual-compatibilizer, the impact strength of the composites increased greatly.…”

The mechanical properties of polymer-based composites are generally determined by the interfacial adhesion between the inorganic component and the polymer itself. In this work, high-density polyethylene (HDPE) composites were prepared with polydopamine(PDA)-modified short basalt fibers (D-BF) as an inorganic filler, in which the interface between HDPE and D-BF was mediated by maleic anhydride-grafted polyethylene (PE-g-MAH) and maleic anhydride-grafted poly(ethylene-co-octene) elastomer (POE-g-MAH). The adding mass ratio of both the compatibilizers had a significant effect on the mechanical properties of the prepared HDPE/D-BF composites. When total 5 wt% of both PE-g-MAH and POE-g-MAH with a mass ratio of 1/3 was intro-

“…Due to the great and outstanding combination of physical and mechanical features, natural fiber composites are now widely used in a wide variety of fields and are used in civil construction, machinery construction, electrical and electronic apparatus, automobile industrial factory, in making aircraft, and much more [5][6][7][8]. Much research has been done on synthetic composites of synthetic matrix-based synthetic fibers (e.g., glass, carbon, nylon, and Kevlar) [9,10]. SF reinforced TP or TS composites are effective on NF strengthened composites due to their advanced strength, durability, deterioration, and moisture resistance features.…”

In this article, the effects of chemical treatment (sodium dodecyl sulfate, SDS, and SDS pretreated benzoyl chloride) on the physicomechanical, morphological, and weather tests of calotropis gigantea fiber (CGF) reinforced polypropylene (PP) composites were investigated. The outcomes show that CGFs act as reinforcing fillers enhancing the physicomechanical properties (e.g. tensile strength, tensile modulus, and impact strength, hardness, and water absorption (WA)) of composites. PP/CGF composites with benzoyl chloride after SDS pretreatment indicate better mechanical properties than SDS treated and untreated fiber composites. The interfacial properties were examined by scanning electron microscopy (SEM) and it was performed that the interfacial interaction between PP and CGF was enhanced due to the treatment of fibers, which verified the obtained mechanical properties of the composites. The water absorption test showed that SDS pretreated benzoyl chloride-treated CGF composites exhibited less water absorption than both SDS-treated and untreated composites. Weather tests have shown that SDS pretreated benzoyl chloride-treated composites exhibited less loss of tensile strength and tensile modulus compared to both SDS-treated and untreated composites in terms of their decay time.
