Title:
INVESTIGATION OF MECHANICS OF REINFORCED PLASTICS, PART II.
Corporate Author:

Abstract:
Four aspects of the mechanics of reinforcement have been studied 1 shrinkage stresses in thermosetting resin-fibrous glass systems containing relatively few glass elements 2 improvement of a method for directly testing the strength of the resin-glass fiber joints 3 a detailed investigation of flexural failure mechanisms in fabric-based laminate, and 4 particular solutions for aeolotropic plate behavior derived from the more general theory previously developed. In the same order, the significant findings include 1 high axial stresses can be created in fibers, depending upon their length, diameter, surface condition and relative orientation 2 polyester-glass fiber joint strengths reach a maximum value, contingent upon cure exotherm, while stronger epoxyglass fiber specimens usually fail before interfacial fractures occur 3 some of the modes of flexural fracture and the test method-material-strength interactions which apparently occur remain obscure though good progress was made, and 4 interlaminar stress and strain effects in plate specimens, thought to be operative from common qualitative experimental observations are substantiated by theoretical analysis.
