This paper reports on the synthesis of Cannabis indica fiber-reinforced composites using Urea-Resorcinol-Formaldehyde (URF) as a novel matrix through compression molding technique. The polycondensation between urea, resorcinol, and formaldehyde in different molar ratios was applied to the synthesis of the URF polymer matrix. A thermosetting matrix based composite, reinforced with lignocellulose...

Resin Transfer Molding, as a method for the manufacture of advanced ber reinforced composite materials, is attractive because it ooers the possibility of lower manufacturing costs and more complex shapes than the traditional manufacturing methods. A major issue in this new manufacturing process is the elimination of void spaces in the resin ll operation, so that products with high quality are m...

Environment-friendly “green” nanocomposites were fabricated from a starch-based, dispersion-type biodegradable resin and cellulose nanofibers. The mixture of the dispersion-type biodegradable resin and cellulose nanofibers were blended well by using a mixer and/or a stirrer. Composites were prepared by conventional hot pressing at a constant temperature of 140oC and at pressures from 10 to 50 M...

Room temperature cure epoxy resin has been doped with SiC nanoparticles through an ultrasonic cavitation process. The modified resin was then utilized in a Vacuum Assisted Resin Transfer Molding (VARTM) process with satin weave carbon fibers to manufacture nanophased composite panels. The nanoparticles were spherical in shape and about 29 nm in diameter. The loading of nanoparticles into the re...
