Tensile test on pine needles and crack analysis of pine needles short fiber reinforced composites
نویسندگان
چکیده
Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is tested for the statistical analysis.ASTM D5045 standard is used for the crack analysis of a number of specimen .Paper tab method is used for the tensile testing of the pine needles fiber. Measuring the modulus and strength by conducting a tensile test by paper tab method is very popular in fibre manufacturing industry. The experimental procedures to determine the axial Young’s modulus and ultimate axial tensile strength of single fibre as well as fabrication procedure and crack analysis of pine needles short fiber reinforced composites have been explained in detail in this work.

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...

The creep behavior of basalt fiber reinforced epoxy (BFRE) and glass fiber reinforced epoxy (GFRE) composites was studied through tensile testing at high temperature. To study the effect of reinforcing epoxy, the micro glass powder (MGP) was added at various volume percentage into the epoxy resin in BFRE composites. The initial strain for all the specimens were evaluated and compared with each ...

To investigate properties that might be related to utilization, needles were sampled on one tree of each of the four major species. Tensile strength was measured on loblolly needles only; it ranged from 4,630 to 6,980 psi. Maximum load averaged 4.1 pounds per needle, with a modulus of elasticity of 220,000 psi. Specific gravity (ovendry weight, green vol~) of individual needles of the four spec...
