Abstract
Renewable resources such as natural fibers in the field of fiber reinforced materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating eco-friendly materials. In views of enormous advantages a study on green composites usingSaccaharum cilliarefiber as a reinforcing material and urea-formaldehyde (UF) as a novel matrix has been made. First of all urea-formaldehyde resin synthesized was reinforced withSaccaharum cilliarefiber. Reinforcement of the fiber was accomplished in three different forms particle (200 micron) reinforcement, short fiber (3 mm.) reinforcement and long fiber (6 mm) reinforcement. Present work reveals that mechanical properties such as: tensile strength, compressive strength and wear resistance of urea -formaldehyde resin (UF) increases to a significant extent when reinforced withSaccaharum cilliarefiber which is found in outsized amount in the Himalayan Region. These mechanical properties mainly depend upon the dimensions of the fiber used. Analysis of results shows that particle reinforcement is more effective as compared to short and long fiber reinforcement. Morphological and thermal studies of these composites have also been carried out.
Highlights
Renewable resources in the field of fiber reinforced polymeric materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating eco-friendly material1-2
This fibrous material belonging to Himalayan region is being used by the people of the Himachal Pradesh for making low cost articles like ropes, bags, socks, boots, mats, etc
The fibers were washed thoroughly with distilled water and dried in an air oven at 80°C for 12 h and kept in a vacuum oven at 70°C for 3 h before preparation of composites. This fiber was used in three forms as shown below: 1. Particle reinforcement Saccharum cilliare fibers were grinded to a powder and filtered through a sieve of pore size 200 microns
Summary
Renewable resources in the field of fiber reinforced polymeric materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating eco-friendly material. Renewable resources in the field of fiber reinforced polymeric materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating eco-friendly material1-2 Because of their enormous properties such as low density, good mechanical performance, relatively low cost, low weight, less damage to processing equipment, good relative mechanical properties, unlimited availability and problem-free disposal, natural fibers offer a real alternative to the technical reinforcing fibers presently available.An interesting environmentally friendly alternative for the use of synthetic fibers as reinforcement in engineering composites are lignocellulosic natural fibers such as flax, Grewia optiva, Pine needles, Hibiscus sabdariffa etc.. Literature survey has revealed that no work has been done on utilization of this raw fibrous material as reinforcing agents in polymer composites
