This book was released on 2018-07-13 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interlaminar fracture toughness of 2-D graphite/epoxy woven composites was determined as a function of stacking sequence, thickness, and weave pattern. Plain, oxford, 5-harness satin, and 8-harness satin weaves of T300/934 material were evaluated by the double cantilever beam test. The fabric material had a G (sub Ic) ranging from 2 to 8 times greater than 0 degrees unidirectional T300/934 tape material. The interlaminar fracture toughness of a particular weave style was dependent on whether the stacking sequence was symmetric or asymmetric and, in some cases, on the fabric orientation.

This book was released on 1986 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of electron radiation on the interlaminar fracture toughness of a graphite/epoxy (T300/934) composite were investigated using the double cantilever beam (DCB) test to determine the Mode I critical strain energy release rate GIc and the edge delamination tension (EDT) test to determine the mixed Mode I and II critical strain energy release rate Gc. The effects of test temperature on the Gc of both the nonirradiated and irradiated material were determined. A miniature DCB and EDT test specimen was developed, and the results from the miniature specimens were compared with those from standard DCB and EDT test specimen geometries.

This book was released on 1987 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five graphite/epoxy composites containing toughened epoxies prepared at Dow Chemical and AS-4 graphite fibers from Hercules have been studied in Mode I, mixed mode, and Mode II to determine their delamination fracture toughnesses Gc and the controlling micromechanism of fracture. The Gc values were determined using split laminate specimens. The delamination fracture process was observed in real time in the scanning electron microscope. To increase delamination fracture toughness, both an improved interface as well as higher resin toughness were found to be required. Increasing Mode II loading, particularly of the more brittle systems, gives a significantly greater resistance to crack propagation as measured by the total energy release rate required to propagate the crack.

This book was released on 1984 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three approaches for evaluating mode I interlaminar strain energy release rates in graphite/epoxy composites were compared using experimental data from double cantilever beam specimens. Expressions for evaluating strain energy release rates were arrived at based on assumptions regarding specimen geometry and material behavior. The calculations included the direct method of the J integral approach, a compliance calibrated approach and an analytical equation derived from small deflection, linear beam bending theory. The J integral approach accounts for both linear and nonlinear material response, whereas the compliance calibrated and linear beam bending methods assume linear material behavior. Experimental observations of several material systems indicated a nonlinear elastic material response. Interlaminar strain energy release rates were found to be overestimated by methods assuming linear material behavior. Permanent deflection was seen to accumulate in the arms of the double cantilever beam specimen as the crack surface area increased. This component of deflection must be accounted for in all forms of analysis when using double cantilever beam specimens.
