Abstract:

Research was continued on the potential of filament wound composites. Difference in principal stresses were determined photoelastically for composites reinforced with broken fibers. Glass rod reinforced composites, cured at room temperature, and .010 in. diameter glass fiber reinforced specimens cured at 200 F, were evaluated in tension. The failure in the .010 in. diameter glass fiber reinforced specimen was observed at a distance of 10D to 40D from the gap. The failure of the glass rod reinforced specimen occurred as expected at the point of discontinuity. Effects of coatings on fiber strength were investigated. Preliminary data indicates coatings to be advantageous for the preservation of E-glass strength. Author
