Description

FIELD OF THE INVENTIONThe present disclosure relates to a system for making natural fiber reinforced hybrid composite laminates having a dual epoxy matrix. More particularly, the present invention relates to a system for making an environmentally friendly composite laminate reinforced with natural fibers and bonded to a hybrid epoxy matrix system. The reinforcement of the laminate produced is effected by the incorporation of natural fibers.BACKGROUND OF THE INVENTIONEnvironmental concerns regarding plastic fouling, resource depletion, and CO2 fuß of synthetic materials have advanced research into environmentally friendly alternatives for fiber reinforced polymeric composite system. Conventional composite manufacturing systems using fiberglass reinforced plastic (GRP) and carbon fiber composites produce non-biodegradable materials, which are energy intensive and difficult to recycle.Existing natural fiber reinforced composite (NFRC) production systems utilize materials such as jute, hemp, flax, coco fiber, and kenaf as reinforcements with polymer matrices. However, these systems frequently encounter restrictions in component integration, in particular in the areas of thermal stability control, water resistance and improvement of the interfacial bond, without the need for expensive processing equipment for this purpose.Current systems using cardanol-based epoxy resins (derived from cashew nutshell liquid) due to their partial biodegradability often require special curing equipment operated at elevated temperatures or for extended periods of time, which limits their industrial scalability in resource-constrained production environments. Moreover, conventional fiber treatment systems are not optimally integrated with hybrid epoxy matrix treatment equipment to maximize fiber-matrix bonding and mechanical strength.The present invention overcomes these limitations by an integrated system that combines chemical treatment of natural fibers, dual epoxy matrix fabrication, controlled laminate fabrication, and comprehensive testing capabilities to produce environmentally compatible composites with improved mechanical properties at ambient cure temperatures without requiring special high temperature processing equipment.SUMMARY OF THE INVENTIONThe present disclosure relates to a system for producing hybrid natural fiber-reinforced composites having a dual epoxy resin matrix. The present invention relates to a system for producing hybrid composite materials with a dual epoxy resin matrix and reinforced with natural fibers. The system integrates chemical treatment of natural fibers, the production of a unique dual epoxy matrix, the production of composite laminates by hand lamination, controlled curing processes, and the testing of mechanical properties to produce environmentally compatible, structurally robust composites of jute and hemp fibers.The present disclosure is directed to providing a system for making hybrid natural fiber reinforced laminates having a dual epoxy matrix. The system comprises: a) a chemical treatment unit for alkaline treatment of natural fibers with sodium hydroxide solution (NaOH); b) a matrix processing unit for mixing epoxy resins with additives in predetermined ratios; c) a laminate manufacturing unit for applying the composite materials, comprising a shaping region with release agent application devices; d) a curing unit for initial and subsequent post-curing of the composite material; and e) a testing unit for evaluating the mechanical properties of the composite materials produced.It is an object of the present disclosure to provide a system for making hybrid natural fiber reinforced laminates having a dual epoxy matrix.Another object of the present disclosure is to provide a comprehensive system for making natural fiber reinforced hybrid composites with improved mechanical properties using environmentally compatible materials.Another object of the present disclosure is to use a dual epoxy matrix system that optimizes the interface between natural fibers and resins.Another object of the present disclosure is to provide a system that enables consistent production of composite laminates having predetermined fiber volume ratios for targeted mechanical performance.Another object of the present disclosure is to evaluate and compare the mechanical properties of various fiber compositions to determine optimum configurations for particular applications.In order to further clarify the advantages and features of the present disclosure, the invention will be explained in more detail with reference to specific embodiments that are illustrated in the accompanying drawings.

The system includes a chemical treatment unit that treats natural fibers with caustic soda solution to improve fiber-matrix adhesion by removing surface contaminants and modifying fiber surface chemistry. This unit comprises special containers for solution treatment, fiber dips, washing stations and drying chambers in order to ensure a constant quality of the fiber treatment. The system includes a matrix conditioning unit for preparing a dual epoxy resin matrix that precisely mixes the LY556 epoxy resin in a 60:40 ratio with Green epoxy 1153, adds 1.5 weight percent hexamine powder as a cure accelerator, and adds 10 weight percent of the HY951 hardener to the total resin mixture. The laminate manufacturing unit uses a standardized rectangular steel mold of defined dimensions equipped with release agent applicators, die metering systems, fiberboard placement mechanisms, and compression tools to provide adequate wetting and bubble removal during the hand lamination process. The curing process takes place in special chambers in which temperature, air humidity and exposure conditions are controlled. It begins with an initial curing phase, followed by a longer cure at room temperature and a post cure in sunlight. The cured laminate sample is then taken using the sampling unit which includes precision cutters and surface treatment mechanisms before being evaluated in the test unit which includes a three point bend tester and compressive strength testing machines with data acquisition functions. The comprehensive system ensures reproducible production of high performance natural fiber composites with optimized mechanical properties for various structural applications.In an exemplary embodiment, layers of jute and hemp fibers are arranged in specific volume ratios (20%, 25% or 30%) alternately with the prepared matrix material. The dio Di DiThe present invention relates to the production of an environmentally friendly composite laminate reinforced with natural fibers and bonded to a hybrid epoxy matrix system. Reinforcement is achieved by the use of natural fibers which are renewable, biodegradable and available in large quantities as agricultural byproducts. These fibers not only contribute to the reduction of environmental waste, but also impart desirable mechanical and physical properties to the laminate such as high specific strength and rigidity, low density, and good thermal insulation.The system includes a matrix conditioning unit for fabricating a dual epoxy matrix system. The matrix conditioning unit formulates the mixture of conventional epoxy resin and bio-based green epoxy resin and additionally modifies it with synthetic hardener and binder to allow effective room temperature curing. This unique dual matrix resin combination provides a balanced ratio of performance to sustainability and replaces the petroleum-based ingredients in part with bio-renewable alternatives. The resulting composite has improved environmental friendliness as compared to fully synthetic composites while maintaining structural integrity and durability.The system includes a chemical treatment unit that alkaliifies the fibers with sodium hydroxide. This improves fiber-matrix interfacial adhesion by removing surface contaminants, lignin, and oils. This treatment significantly improves the mechanical bonding of the fibers to the matrix and provides better load transfer between matrix and reinforcement. The system comprises a laminate preparation unit for producing the composite laminate. The composite material developed is designed for structural applications with low to medium load, in which sustainability, weight reduction and vibration are of decisive importance, such as in vehicle interior equipment, packaging, consumer goods and lightweight boards. By integrating natural reinforcements and partially bio-based resins, this material is a step toward more environmentally friendly composite technologies. Although not fully biodegradable, the lower dependence of the composite on fossil resources and the use of agricultural waste positively contributes to environmental protection and resource efficiency.In one embodiment, the system uses two types of fiberboards as the reinforcing material: jute fiberboards and hemp fiberboards. The jute sheet used had a thickness of about 0.56 mm and a basis weight of 300 g / m 2 and was obtained in woven form (sheet). For the final composite laminate, a jute sheet was used in the core layer (middle layer). Prior to use, the jute fiber was subjected to an alkaline treatment with sodium hydroxide (NaOH) to improve fiber matrix adhesion. Two woven hemp fiber sheets each about 0.56 mm thick and 450 g / m 2 served as the top and bottom layers of the laminate. Hemp offers high rigidity, thermal stability and higher cellulose content compared to jute, which contributes to the general mechanical strength of the composite material. The sheets were additionally chemically treated to ensure uniform interfacial adhesion. The system also uses several matrix materials, namely epoxy resin LY556, green epoxy-1153, hardener HY951 and hexamine powder. For laminate production, the system uses 60% of the epoxy resin LY556, 40% of the green epoxy-1153, 10% of the curing agent HY951 of the combined resin mixture (LY556+ green epoxy 1153) and 1.5% of the hexamine powder. The system also uses sodium hydroxide (NaOH) pellets for alkaline surface treatment of fibers, using high purity (99%) pellets for preparing a 5% NaOH solution, using distilled water for preparing the alkaline solution and washing the treated fibers, using silicone and metal molds as a release surface for lay-up, applying a release agent to the mold surface to prevent adhesion of the composite during curing, using silicone grease as the release agent. The system uses brushes and rollers to apply the resin manually.In one embodiment, the system subjects the fiber to an alkaline treatment. To improve fiber-matrix adhesion, an alkaline treatment (mercerization) is carried out with sodium hydroxide (NaOH). The system includes a chemical treatment unit that facilitates the preparation of an alkaline solution. At this time, an aqueous solution of NaOH (5%) is prepared with distilled water, the fibers are immersed in the alkaline solution for 1-2 hours, and the wet fibers are post-treated. The fibers are soaked in the solution for 1-2 hours. The fibers are thoroughly rinsed with distilled water until a neutral pH is reached. The treated fibers are air dried for 24 hours. This treatment helps remove hemicellulose, waxes and lignin that inhibit fiber-resin bonding.In one embodiment, the fabrication mold is used to produce concrete samples. In preparing the composite sample, silicone grease is applied to the inner casting surface 15 minutes prior to casting to improve removal of the material.In one embodiment, the system includes a matrix preparation unit configured to prepare a resin matrix, the preparation process including: a calculated weight of the epoxy resin LY556:Green epoxy 1153 was mixed at a ratio of 60:40; the resin mixture was gently stirred to achieve a uniform mixture; hexamine powder was added at a concentration of 1.5% (based on the total resin mixture) to promote curing; a hardener (10 weight percent) was added to the total resin mixture; and the matrix was used exactly 10 minutes after stirring to ensure proper processing time.In one embodiment, a rectangular steel mold having an internal cavity dimension of 250×20×20 mm was used for casting to produce the laminate sample in order to maintain a constant volume in the laminates. Silicone grease was used as a release agent. Initially, the mold was stored and coated with a layer of silicone grease to facilitate easy removal of the laminates. The matrix was prepared by mixing the epoxy resin LY556 and Green epoxy 1153 in the ratio 60:40 in the order given above. This resin mixture was gently stirred for up to 15 minutes to obtain a uniform mixture. Then, hexamine powder was added at a concentration of 1.5% (based on the total epoxy mixture) to speed the curing. Note that the HMTA powder should be crushed into fine particles when added for better mixing. This mixture was also gently stirred for up to 15 minutes to obtain a uniform mixture. Now, the important component of the whole mixture, i.e. the hardener HY951, is taken in an amount of 10% by weight (based on the whole epoxy mixture) and added to the prepared whole resin mixture. After the hardener has been added, the mixture is stirred for only 5 minutes to produce a uniform mixture. First, a layer of the matrix is poured into the die (mold) while being covered 1-2 mm deep in the die, and then the first layer of fiberboard is laid thereon, and then another layer of the matrix is poured. A similar process is performed for all other layers to produce the composite. Concern that the fibreboards tend to float in the matrix. Thus, completely dip them into the matrix by pressing them down into the matrix. Let the die after casting the composite be as it is for 120 minutes to allow it to cure first. Note that even the least displacement of the die in these 120 minutes may result in bulging of the die and thus deformation of the entire die. The matrix was used exactly 10 minutes after stirring to ensure proper processing time. To the entire resin mixture was added a curing agent (10%). To accelerate curing, hexamine powder was added in a concentration of 1.5% (based on the total resin mixture). The resin mixture was gently stirred for uniform mixing. A calculated weight epoxy resin LY556:green epoxy 1153 was mixed in a ratio of 60:40 to a sample 13. Avoid exposing the laminate to the sun during these 120 minutes, since this can lead to foaming and air bubbles. Always use a cool, shaded, and dry spot for initial curing. Here, no load was applied to maintain the uniform thickness of the composite material. Care was taken to ensure complete wetting of the fiberboard to prevent the formation of air bubbles and to avoid the shifting of the die. The assembly was cured for 24-48 hours at room temperature (25-35°C) and normal air pressure. After post curing, the composite laminate was removed from the structure and stored in the sun for 24 hours for complete curing. Post curing increases crosslinking of the matrix fibers by rearranging the polymer chains, cures the uncured matrix, and induces internal stresses generated during polymerization of the matrix.A composition ratio of the respective materials is shown in the following Table 1.

The ratio thus always remains the same irrespective of the weight of the individual elements. The sample is removed from the mold and cleaned with a clean cloth to remove the release layer. The sample is then cut out using a professional electric crosscut saw or hand grinder according to the dimensions specified in the ASTM standards for the respective test method.The prepared samples are subjected to tests in which the bending properties and the pressing properties of the prepared laminate are tested.In one embodiment, samples are developed with three different fiber volume ratios (20%, 25%, 30%) and tested with a 3-point deflection test set-up under load-driven motion (deflection test) to determine the most suitable volume fraction. The aim is to investigate the bending and compression properties of dual epoxy composites reinforced with natural fibers (jute and hemp). All fiber volume ratio (FVR) variations are tested for both bending and compression properties (a total of six samples). The sample with the best FVR is selected as the final application material.The present invention relates to a system for producing natural fiber reinforced hybrid composite laminates having a dual epoxy matrix. The core goal is the development of a durable, inexpensive and partially biobased composite that can be produced in a simple manual process and is suitable for semistructural applications. The invention focuses on the use of renewable natural plant fibers and the partial replacement of synthetic resins with bio-based epoxy resins, thereby reducing the dependence on fossil raw materials.An important advantage of this invention is the possibility of achieving curing at room temperature, thus eliminating the use of energy-intensive curing equipment such as ovens or autoclaves. This makes the process more energy efficient and environmentally friendly. The natural fibers used in the composite material are subjected to chemical treatment, particularly alkaline treatment with sodium hydroxide, to improve their surface properties. This treatment significantly improves the adhesion between the fibers and the resin matrix, thereby eliminating frequent limitation of conventional natural fiber composites, in which weak interfacial bonding reduces mechanical strength.The system enables production by manual hand laminate, which enables production without complicated infrastructure. This makes it particularly suitable for decentralized or low-capital production plants and at the same time ensures the consistency and reliability of the end product. The resulting composite laminate is carefully designed to provide a controlled thickness, an optimized strength-weight ratio, and suitable fiber-matrix ratios. As a result, it is ideally suitable for use in vehicle interior trim, furniture, packaging and other environmentally friendly consumer products.Another noteworthy aspect of the invention is the use of various natural fiber types, such as jute and hemp, in a layered arrangement. This provides flexibility in the development of composites with customized mechanical, aesthetic, and ecological performance characteristics. The hybrid matrix system consists of a conventional epoxy resin LY556 combined with a 60:40 ratio bio-based green epoxy 1153 cured with a combination of hexamine powder and the standard hardener HY951. This formulation ensures reliable curing at room temperature and provides sufficient mechanical integrity.The invention is distinguished by a practical and cost-effective solution for producing environmentally friendly composite materials which have a performance level comparable to conventional synthetic composite materials in non-critical or easily loadable structural applications. Their particular features - such as a partially bio-based matrix, chemically treated natural fibers, and a hand laminate manufacturing process - contribute to their environmental friendliness, cost efficiency, and mechanical stability. Overall, this system provides a balanced integration of renewable resources, simple processing, and functional performance, and is thus a viable option for persistent material development in industrial applications.The drawings and the foregoing description show examples of embodiments.
