Abstract: A dynamic mixer to mix at least one curing agent and at least one resin system in the proportion of at least 2.5:100 to obtain a homogenous curative composition, wherein said mixer comprises a stirring chamber (5) provided with a motorised stirrer (4) suspended from the top of the chamber (5) and a siphon (6) at the bottom; at least one inlet hose (h1) connected to the stirring chamber at one end and pumping means (p1) at other end; the pumping means (p1) pump at least one curing system to the stirring chamber through the at least one inlet hose (h1); at least one inlet hose (h2) connected to the stirring chamber at one end and pumping means (p2) at other end; the pumping means (p2) pump at least one resin system to the stirring chamber through the at least one inlet hose (h2); and frame to setup the dynamic mixer. The proportion of diameter (A) of the stirring chamber (5); length (B) of the stirring chamber (5) from a top closure to a bottom opening of the chamber (5); and the length (C) from the bottom opening of the chamber (5) and a top of the siphon (6) may vary only in the ratio of 1: (2.6-3.0): (1.1-1.3) i.e. [(A):(B):(C)] to obtain the homogenous curative composition comprising 2.5 phr curing system per resin system.

Abstract: Bio-composite pultruded products (100, 104, 107, 110, 114, 117) either in “I” profile or “Plate” profile of higher cross sectional area where said products consisting essentially natural fibres selected from hemp, jute, sisal and. flex as core impregnated with a resin system comprise of at least one resin, curing system comprising a curing agent and an accelerator, a filler, a thinner, pigment or any other additives; encapsulated between bi-directionally and/or uni-directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with said resin system are provided. in another bio-composite pultruded products either of “I” profile or “Plate” profile of higher cross sectional area where said products consisting of plank of short fibers bagasse premixed with the said resin system as core is enclosed between the natural fibers selected from hemp, jute, sisal and flex impregnated with the resin system which is further enclosed between bi-directionally and/or uni-directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with the resin system. The system and method for the preparations of said bio-composite pultruded products, are also illustrated herein. These products lead to a significant reduction in weight and reduction in density with higher stiffness and bending strength. The present bio-composite products are encapsulated by fabrics in the peripheral area brings more integrity uniformity of jute materials. This leads to a significant cost reduction in a without sacrificing much tensile strength.
