The Impact

Abstract Glass Fiber Composite laminates were subjected to low velocity impact at 2 m/s using a semi-hemispherical drop tower tup. Impact damage were observed and recorded over a wide range of temperatures. Of particular interest is the post impact strength at these test temperatures. The effect of temperature variation on the impact damages and on the residual compressive buckling strength and elastic modulus is evaluated based on the test results.

The Impact

A new type of modified phenolic resin/glass fiber composite is introduced. Phenolic resin was modified with 2% polyvinyl alcohol(PVA). Test specimens were prepared by mixing and molding. Fourier transform infrared spectroscopy (FTIR) was adopted to investigate its molecular structure. FTIR results showed that long aliphatic chain were introduced into the structure of PR, which could absorb the energy during load was applied on the composite. The toughing mechanism was investigated by comparing the impact strength, bending resistance, tensile strength with non-modified phenolic resin. Results shows that the impact strength of the modified PR/GF composite reaches 53.21 KJ/m2, which is almost 2 times more than that of pure PR/GF composite. Finally, the application of the modified PR/GF composite on shoes head was introduced.

Glass Fiber Composite

In transverse vibrations the element moves to and fro in a direction perpendicular to the direction of the advance of the wave. To determine the vibration characteristics i.e., natural frequencies and mode shapes, modal analysis is a process for a structure or a machine component while is being designed. In real life, aero planes, missiles, rockets, space vehicles, satellites, sub marines etc are modeled as free-free mechanical systems. In this paper an attempt was made to compare natural frequency for two composite materials- ladies finger with Glass fiber composite and Hemp with Glass fiber composite by taking as cantilever beams. The cantilever beam which is fixed at one end is vibrated to obtain the natural frequency, mode shapes at four different modes. A simple low cost demonstration experiment is performed in this paper by using common apparatus in order to compare theoretical, numerical (FEM analysis) profiles of two free-free thin two rectangular composite beams of dimensions 305*49.5* 7 in mm. Keywords: Natural frequencies, Mode shapes, Vibration characteristics, Ladies finger fiber, Hemp fiber, Glass fiber, FEM analysis, Free-Free system.
