“…3 confirms the presence of Si, Al, Ca, Na, Mg, K, Fe and ferric oxides which constitute the composition of basalt [16,17]. In contrary to this result, Abdurohman et al [5] have reported that vacuum assisted resin infusion method yields higher mechanical properties and the pump used to create the vacuum is responsible for the injection of resin into the fabrics.…”

The effect of reinforcement material and manufacturing method on tensile, impact, and hardness properties of glass and basalt laminated composites were studied. Woven glass and basalt fabrics were used as reinforcements along with a thermosetting epoxy matrix to fabricate the laminate composites. The glass and basalt epoxy composites were made using hand layup with compression, vacuum bagging, and vacuum-assisted resin infusion methods. The characterization tests are performed as per the ASTM D638-10, ASTM D256, and ASTM D2240 standard respectively. The basalt epoxy composites show improved mechanical properties compared to the glass-epoxy composites. Further, hand layup, along with compression moulding and resin infusion methods, were found to be beneficial in improving the mechanical properties of the composites. Field emission scanning electron microscopic analysis conveyed the adhesion between fibers and resin as well as the voids retained within the matrix are the dominant factors that determined the mechanical properties of the laminated composites such as tensile, impact strength and hardness.

“…The filler was mixed with polyester resin plus a catalyst and then printed using the hand lay-up method. The hand lay-up technique is the primary method of composite manufacture [8]. The tools required for this method were minimum.…”

“…It seems the more volume fraction and shape, the more defect existed. The factor of making composite specimens and distribution of fibers can cause a decrease in the flexibility value of composite hand lay-up manually [8]. It is because when the process of making composite materials with the manual hand lay-up method, there will be a tendency for fibers to gather at a certain point and uneven fiber distribution.…”

Kalimantan has abundant natural resources, including wood. The physical properties of wood have varying strength and flexibility and could replace concrete reinforcement steel. In this study, the mechanical properties and sound insulation of one of Kalimantan's natural fiber combined with polyester matrix were investigated. Natural fibers used were teak wood (Tectona Grandis) with sawdust and wood chips. Specimens were made using the hand lay-up method with a wood volume fraction variable of 25%, 35%, and 50%. Afterward, the bending, morphology, and sound insulation tests were carried out. In this study, it can be concluded that the higher wood volume fraction used, the higher the ability of sound insulation. Conversely, it reduces the modulus of elasticity. Besides, the form of sawdust fillers has a better ability than wood chip fillers in terms of sound insulation and the modulus of elasticity.

“…Samples were produced by varying manufacturing technique (vacuum bag or infusion), resin types, as well as fiber combinations, as shown in Table I. Vacuum assisted techniques were used to fabricate the samples as these produced less bubble than hand lay-up process [6]. All samples were fabricated by combining two fiber types (A and B), with 9 plies for each fiber.…”

“…Some previous studies reported effect of different manufacturing method, resin system as well as fiber architectures and combination on composite properties. Abdurohman and coworkers compared tensile modulus and strength as well as morphology of samples prepared by hand lay-up, vacuum infusion and vacuum bagging on E-glass EW 185/Lycal composites [6]. They found that vacuum infusion samples had better modulus and strength than those of vacuum bagging and hand lay-up.…”

Glass fiber composites were fabricated from two different manufacturing techniques, vacuum infusion and vacuum bag, two resin types (epoxy, vinyl ester), as well as and two fiber combinations (S-glass and E-glass). The analyzed properties were tensile modulus, strength as well as compression strength, with relation to sample morphology and fracture surface due to compression. The results showed that all variables and their interaction did not significantly influence tensile modulus, while manufacturing methods was the only significant variable influenced tensile strength. The results showed that vacuum infusion samples had better tensile strength than those produced by vacuum bag due to less resin and bubbles. In term of compression, the change on strength was highly contributed by resin type and fiber used on layer A. Composites samples with epoxy resin showed better strength than those of vinyl ester may be due to better initial resin property. While, imbalance transfer load and fiber density inhibiting resin penetration and causing resin rich samples produced lower compression strength for samples with S-glass applied to layer A than E-glass. Further analysis on fracture surface showed that most samples failed on compression test due to shear, kink and resin break.
