Properties of rubber‐modified cellulose‐fiber‐epoxy laminates

Properties of Rubber-Modified Cellulose-Fiber-Epoxy laminatesCellulose fibers are a potential source of cheap reinforcement for brittle materials.Already they are used commercially to improve the strength and fracture toughness of cements.'s2These materials also displayed a slow crack growth resistance curve.Cellulose fibers are also widely used in the strengthening and toughening of polymers.Cellulose-fiber-reinforced polymer composites (CPC) can replace metals in many applications.They offer superior corrosion resistance, lower costs, lighter weight, good fracture resistance, and better flexibility in part design.Two most widely used methods for fabricating CPC materials are: (a) impregnation of wood with liquid monom e r ~, ~. ~ and (b) compounding of polymer with cellulose fiber^.^,^Improved physical mechanical properties have been achieved for these materials.Recently, we successfully synthesized cellulose-fiberepoxy laminates with improved mechanical and fracture proper tie^.^In this note, we report the synthesis and
