“…The composite was left to dry in an open environment for 24 hours, followed by a 2-hour heating period in an oven at 40 °C. The specimens were coded NCAP (Non-Carbon Active Powder), LCAP (Low Carbon Active Powder), and HCAP (High Carbon Active Powder) [21]. The process of making composite specimens can be seen in the Fig.…”

“…Furthermore, adding CAP offers the advantage of filling the voids between the fiber and the matrix. This configuration allows for improved infiltration and wetting of the composite gaps by the epoxy resin, resulting in enhanced mechanical bonding [21]. This mechanical bounding provides an opportunity to increase the tensile strength of LCAP and HCAP.…”

“…The results indicate that the composite material can be well bonded, thus contributing to the flexural strength. The distribution of carbon powder in the epoxy matrix is high, non-uniform and tends to form agglomerates [17,21,29]. From this study, the use of ALF natural fibres as reinforcement in composite materials offers several advantages, including lower weight and cost compared to synthetic fibres, as well as being environmentally friendly and sustainable.…”

This research focuses on the successful development of Agel Leaf Fiber (ALF)-Epoxy composites added with Carbon Active Powder (CAP) and printed using the Vacuum Pressure Infusion (VAPRI) method. Considering the importance of determining the mechanical properties of composites as raw materials for making fishing boats, this research aims to determine the use of Agel Leaf Fiber (ALF) in polymer matrix composites. The composite morphology was analyzed using Scanning Electron Microscopy (SEM) and ImageJ software. The mechanical properties evaluated included Tensile Strength, Flexural Strength, and Hardness. The composite was prepared by incorporating CAP in varying volumes of 0 %, 10 %, and 30 % with a fixed ALF percentage of 40 %. The results showed that the addition of CAP significantly increased the tensile strength to 128.51 MPa, with 0.068 % elongation, 1787.39 MPa modulus of elasticity, and a hardness value of 75.2 HD. Furthermore, the addition of 10 % carbon exhibited a remarkable improvement in flexural strength, reaching 238.51 MPa. This improvement could be attributed to reduced porosity, resulting in enhanced bonding between ALF-CAP-Epoxy components. The flexural strength of the composite with the highest CAP content experienced a significant increase of 238.51 MPa. Thus, Agel leaf fiber has the potential to be used as a reinforcing material in the manufacture of composites and is applied in the manufacture of environmentally friendly fishing boat bodies

Resin selection has a crucial role in determining the properties and performance of GFRP composites; this study aims to investigate the effects of different resin types, specifically epoxy, bisphenol, ripoxy, and polyester, on the mechanical strength of GFRP composites.The composites were fabricated using the conventional method of hand lay-up technique with a fiber to matrix ratio of 60:40 wt%. The glass fibre laminate arrangement consists of 4 layers, two layers of Woven Roving Mat (WRM) fibres (0/90) and 2 layers on the outer side of the Chopped Strand Mat (CSM). The composite specimens were molded using the ASTM D-838 tensile test standard and ASTM D-790 for the bending test.The research results found that the maximum tensile strength was obtained by GFRP composite with ripoxy matrix type of 181.6 MPa, strain of 0.028%, and flexural strength of 1387 MPa. Composites using polyester matrices can generally be classified as splitting in multiple areas where failure occurs in various areas, but the composite has very high strength.Material experiments conducted on a scientific laboratory scale may not fully reflect the behaviour of composites in actual conditions. Furthermore, aspects such as environmental influences, sustained stresses, or fatigue effects may need to be considered in further research. This evaluation also does not consider the effects of long-term exposures or ageing on the mechanical properties of GFRP composites. Investigating the behaviour of materials over long periods can provide important insights into their durability and reliability in practical applications.In GFRP composites, the application of resin to the fibres is critical. The performance and mechanical characteristics of GFRP composites are largely determined by the polymer matrix. Composites with epoxy, polyester, or bisphenol matrices can be compared to composites with the most equivalent tensile strength values, but composites with ripoxy matrices can be suggested. However, the GFRP composite with bisphenol matrix has an excellent bending strength value. As a result, numerous applications exist for implementing matrix selection in producing GFRP composites.The reliability of the tensile properties of GFRP composites was obtained using the ripoxy matrix type. Furthermore, the reliability of the flexural properties of the composites was obtained using the bisphenol matrix type.
