Problems solved by technology

[0009] The main problems with the existing methods known in the art for the manufacture of bio-derived hybrid advanced composites are: (a) low water absorption, (b) inability to impart high fatigue resistance, (c) the method is The resulting composite imparts considerable tensile and flexural strength, and (d) is a complex and expensive process
In addition, the resin used in this method does not impart crystallinity to the product caused by stretching and does not retain its original properties in repeated cycle use

Embodiment 1

[0065] The jute mat and jute fibers were passed through a Doctor Box containing 0.5% maleic anhydride. The jute fiber mat and jute fibers were surface treated with maleic anhydride at 80°C and maintained at this temperature until the fiber mat entered another Doctor Box. The treated jute was then passed through another DoctorBox containing SBR latex with 5% solids content. The SBR latex was grafted onto the treated jute fibers at 150°C and this temperature was maintained until the jute fiber mat was dehumidified. Then, the rubberized jute fabric was passed through phenolic in another Doctor Box. The treated jute is pulled out at a speed of 0.5 m / min, and the fiber is wound in a drum.

[0066] Rectangular shapes of raw material (phenolic impregnated jute) were kept layer by layer in proper sequence. The sequentially arranged prepregs are placed in a compression molding machine. at 150kg / cm 2 Under the pressure and temperature of 160 °C, the desired crosslinking and shape a...

Embodiment 2

[0068] The jute mat and jute fibers were passed through a Doctor Box containing 0.5% maleic anhydride. The jute fiber mat and jute fibers were surface treated with maleic anhydride at 50°C and maintained at this temperature until the fiber mat entered another Doctor Box. The treated jute was then passed through another DoctorBox containing SBR latex with 5% solids content. The SBR latex was grafted onto the treated jute fibers at 90°C and this temperature was maintained until the jute fiber mat was dehumidified. Then, the rubberized jute fabric is passed through phenolic resin. The treated jute is pulled out at a speed of 0.2 m / min. The fibers are wound in the form of drums.

[0069] The component is shaped under tension using specially designed dies. The fabric is stretched in windings of roving and sandwiched in other natural fiber mats under an engineered frame, attached to a compression molding die. Keep the rectangular-shaped raw materials in a layer-by-layer structu...

Embodiment 3

[0071] The jute mat and jute fibers were passed through a Doctor Box containing 1.0% maleic anhydride. The jute fiber mat and jute fibers were surface treated with maleic anhydride at 80°C and maintained at this temperature until the fiber mat entered another Doctor Box. The treated jute was then passed through another DoctorBox containing SBR latex with 20% solids content. The SBR latex was grafted onto the treated jute fibers at 150°C and this temperature was maintained until the jute fiber mat was dehumidified. Then, the rubberized jute fabric is passed through a phenolic resin. The treated jute is pulled out at 0.5 m / min and the fibers are wound in drums.

[0072] The rest of the steps were repeated as described in Example 1.

Abstract

The present invention relates to a method of manufacturing a biological source hybrid advanced composites. The method comprises the steps of: (a) processing the fibers with a coupling agent; (b) dehumidifying fibers; (c) grafting the fiber and the elastomer or monomer; (d) dehumidifying grafted fibers ; (e) dispersing the fibers in the resin, wherein the resin is dissolved in a solvent, volatile solvent; (f) tensiling and compressing the fiber. The present invention relates to a biological source obtained by the process of the present invention are hybrid advanced composites.

Description

technical field [0001] The invention relates to a method for manufacturing a biological source hybrid advanced composite material and the composite material. In particular, the present invention relates to a method for the fabrication of bio-derived hybrid advanced composites through fibers grafted with elastomeric polymers or monomers. Background technique [0002] There is an increasing demand for natural, biodegradable and / or eco-friendly fibers. Such fibers are low-density materials that yield relatively lightweight composites with high interfacial properties. These fibers not only have obvious cost advantages and easy processing, but also are highly renewable resources. [0003] Dried jute fiber is known for its strength and is an affordable, sustainably obtained fiber. Various chemically treated natural fibers are well known in the art. Rubberized jute fiber is one of them. [0004] Indian Patent Application No. 494 / MAS / 2001 discloses a composite fibre-reinforced ...
