Book excerpt: The advanced composite materials possess characteristics of stiffness and strength which are most desirable for advanced naval aircraft. Glass composite materials, on the other hand, possess the equally desirable characteristic of low cost. The appropriate combination of these many features can be obtained by a suitable blending of the two or more composite materials. Technically, the blending of two or more fiber types in a laminate, can be achieved by (1) mixing the fibers in the tow or roving, (2) intra-ply mixing of glass rovings with graphite tows or, (3) interleaving or interply mixing of two separate fibrous prepreg systems or any combination of the above. There are additional economic advantages to the third approach where prepreg tapes with a common resin system are prepared for two separate fibers: glass and graphite. For this reason the third approach was selected for some further study particularly with regard to the fatigue performance and its relative behavior to prior studies of the separate composites. The specific objective of the program was to utilize a commercially available glass and a commercially available high strength and high modulus graphite with a common epoxy matrix to maximize the technical performance of the hybrid composite in fatigue applications.

Available in PDF, EPUB and Kindle. Book excerpt: Two ternary composite material systems, PR 286/Modmor II/Graphite/S-Glass and PR 286/ HMS Graphite/S-Glass, involving two types of lamination fabrications, namely uniformly distributed interply hybrids and core-shell hybrids, were investigated. The test program included static tests, tensile fatigue tests, shear fatigue tests, modulus degradation studies and microscopic examination. The study shows that hybrid composites perform generally satisfactorily in fatigue and will survive rigorous stress cycling. Distributed interply hybrids show a better mechanical performance than core- shell hybrids. The mechanical behavior of hybrid composites generally follows the rule of mixtures and the rule of mixtures can be used to predict elastic moduli of hybrids. The performance (as a percentage of the fatigue strength at any given life) of 1:1 graphite/glass/epoxy relative to pure HMS GRAPHITE IS BETTER THAN THAT OF 1:1 HTS Graphite/glass/epoxy relative to pure HTS GRAPHITE/EPOXY.

Book excerpt: The objective of this report is to improve the material performance of a graphite/epoxy prepreg composite with particular relevence to its fatigue performance. Fatigue strength and resistance to fatigue damage of Modmor II/ Narmco 5206 composite were improved by interleaving the composite prepreg laminate with glass scrim cloth. Cantilever beam specimens of two fiber orientations were tested under uniform stress fatigue and sequential block loading. Flexural strength studies and the effects of ambient aging of composites on their elevated temperature properties are reported. Besides ambient aging the investigation also included accelerated aging tests on laminates of two different fiber orientations with and without interleaving of scrim cloth. Improvement in the mechanical behavior of graphite/epoxy prepreg composite was obtained with the addition of glass scrim cloth.
Book Synopsis Off-Axis Fatigue of Graphite/Epoxy Composite by : J. Awerbuch
Download or read book Off-Axis Fatigue of Graphite/Epoxy Composite written by J. Awerbuch and published by . This book was released on 1981 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Off-axis static and fatigue behavior of AS/3501-5A graphite/epoxy was studied in an effort to characterize the matrix/interface-controlled failure. Seven different off-axis angles were tested: 0, 10, 20, 30, 45, 60, and 90 deg. Initial (static) and post-fatigue residual strength were obtained together with S-N relationships. Fracture surfaces were examined through photomicrographs and stereo (three-dimensional) scanning electron microscope (SEM) photographs, in order to delineate failure modes, and the results of these inspections are discussed. The off-axis static strength, including scatter, was fully characterized by a polynomial and a nondimensional strength parameter. Essentially, no strength or modulus degradation was observed in the specimens surviving fatigue loading of 106 cycles regardless of the off-axis angle or fatigue stress level. When fatigue stress level is normalized with respect to static strength, all data seem to fall on the same S-N curve. Fatigue failure occurred without any warning or visible damage. Matrix failure characteristics vary with off-axis angle and appear in the form of serrations and axial and transverse cracks. Large scatter in life was observed at all off-axis angles; however, since the number of specimens employed in the present study is not sufficient to provide meaningful statistical S-N data, a more detailed investigation of the off-axis (and angle ply) behavior of graphite/epoxy composites is warranted.
Book Synopsis Compression Fatigue Behavior of Graphite/Epoxy in the Presence of Stress Raisers by : LW. Gause
Download or read book Compression Fatigue Behavior of Graphite/Epoxy in the Presence of Stress Raisers written by LW. Gause and published by . This book was released on 1981 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphite/epoxy composites are being applied to aircraft structures because of their demonstrated capability to reduce weight and increase life. Although composites have better fatigue properties than metals, their behavior differs significantly. Unlike metals, composites exhibit excellent tensile fatigue behavior--the constant amplitude fatigue strength at 107 cycles being close to static ultimate. Compression and reversed loading fatigue behavior in the presence of stress raisers, however, has not been well characterized. This program was therefore undertaken to determine the characteristics of composites under these conditions. Two stress raisers were considered; the first was an open hole and the second was damage resulting from low velocity, hard object impact.

Download or read book Fatigue Behavior of Composites Under Different Loading Modes written by DF. Sims and published by . This book was released on 1977 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue characteristics of S-glass/epoxy (Scoth-ply SP-250-SF1) and graphite/epoxy (Rigidite 5209-T300) laminates were studied for tension and shear loading. Emphasis was placed on fiber orientations where the matrix contribution to fatigue strength is significant. A general regression curve was used for data analysis, and a two-parameter Weibull model was used for reliability studies. An existing plane-stress macroscopic failure theory for static strength was extended to predict fatigue strength. It was found that the fatigue failure theory provides a conservative approach to first-ply failure which should be useful for preliminary design of composite structures.
