Wood polypropylene composites (WPC) of different compositions (30, 40, and 50%) have been prepared using maleic anhydride–polypropylene copolymer of different percentage (5 and 10% relative to their wood fiber content). Tensile, flexural, fracture toughness, and impact test of the prepared WPC were ...

Jute fiber reinforced polypropylene composites were manufactured using a single extruder and an injection molding machine. Raw jute fiber was oxidized and manufactured composites were post-treated with urea to increase the compatibility of the jute fiber with the polypropylene matrix. Both raw and o...

Raw jute fiber was treated with o-hydroxybenzenediazonium salt (o-HBDS) in alkaline media. Raw and modified jute fiber were used to prepare composites by mixing with polypropylene (PP) plastic in different weight fractions (20, 25, 30, and 35%) of jute fiber. The mechanical properties except elongat...

In the present work, coir was chemically treated first with sodium perchlorate and then with 2,4-dinitrophenyl hydrazine (DNPH) to improve the mechanical properties of the coir−PP composites. Untreated, oxidized, and DNPH-treated coir samples at different mixing ratios were utilized to prepare the c...

Jute fiber was treated with o-, m-, and p-hydroxybenzenediazonium salts in neutral media. These modified and raw jute fibers were used to prepare jute-polypropylene (PP) composite containing 20, 25, 30, and 35% by weight fraction. Mechanical properties of composites were studied. It was found that t...

ABSTRACT Jute fiber was treated with three different hydroxy benzene diazonium salts in acidic and basic media. The formation of coupling with lignin in the polymer system was observed by the infrared spectra and nitrogen content estimation. The physico-mechanical properties, viz., tensile strength,...

Abstract The effect of diazonium salts and alkali on some physico‐mechanical properties, viz, tensile strength, tenacity, elongation at break, moisture regain, shrinkage, loss in weight, etc. of jute fiber has been studied. The tensile strength, tenacity, elongation at break, and moisture regain pro...

ABSTRACT Jute fiber was treated with various substituted benzene diazonium salts in the presence of various metal salts (CuSO4, NiSO4, K2Cr2O7, and KMnO4). It was found that metal ions were incorporated into the jute fiber along with the benzenediazonium salts. The quantity of metal (Cu, Ni, Cr, and...
