ABSTRACT
Montmorillonite filled and unfilled controls, jute/treated jute/glass/hybrid composites were prepared at room temperature for three h and under 5 MPa pressure. The composites were post cured at 150 °C for 30 min. A 40% styrene was used as a reactive diluent, and 1% methylethylketone peroxide, 1.5 % cobalt octoate, and 1.5% dimethylaniline were used as initiator and accelerator, and a promoter. Filled and unfilled composites showed good to excellent mechanical and electrical properties, excellent hydrolytic stability and chemical resistance against water acids, alkali, salt solutions; high water absorption tendency (7.9-20.5%), and longer equilibrium times (288-432h). In different environments at 30 °C observed water absorption trend is H2SO4 > HCl > NaOH > H2O > NaCl. Hybrid composites showed intermediate properties of their parent composites. MMT filled treated jute (46), and unfilled glass (48), and MMT filled glass (48) composites revealed Barcol hardness between the suggested range of 45-65 for scratch and wear resistance proof materials. The nature of the reinforcements, matrix, and filler; fiber treatment, environmental conditions, etc., had affected studied properties and water absorption behavior.
