This book was released on 2012-07-10 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third volume of this six-volume compendium provides methodologies and lessons learned for the design, analysis, manufacture, and field support of fiber-reinforced, polymeric-matrix composite structures. It also provides guidance on material and process specifications and procedures for using the data that is presented in Volume 2. The information provided is consistent with the guidance provided in Volume 1, and is an extensive compilation of the current knowledge and experiences of engineers and scientists from industry, government, and academia who are active in composites. The Composite Materials Handbook, referred to by industry groups as CMH-17, is a six-volume engineering reference tool that contains over 1,000 records of the latest test data for polymer matrix, metal matrix, ceramic matrix, and structural sandwich composites. CMH-17 provides information and guidance necessary to design and fabricate end items from composite materials. It includes properties of composite materials that meet specific data requirements as well as guidelines for design, analysis, material selection, manufacturing, quality control, and repair. The primary purpose of the handbook is to standardize engineering methodologies related to testing, data reduction, and reporting of property data for current and emerging composite materials. It is used by engineers worldwide in designing and fabricating products made from composite materials.

This book was released on 1985 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initiation of delamination in graphite/epoxy laminates was investigated both analytically and experimentally and the effect of effective ply thickness on this phenomenon assessed. Three different laminate families were investigated: [±15n]s,[±15n/0n]s, and [0n/±15n]s, with the normalized effective ply thickness, n, varying from 1 to 5. Delamination initiation was detected using the load drop technique in conjunction with edge replication. Initiation was determined to have occurred when a load drop was detected and a delamination initiation was confirmed on the replication of the specimen edge. Two different analytical techniques were used t-o correlate the measured delamination initiation stresses: the previously proposed strain energy release rate approach and the Quadratic Delamination Criterion which is introduced herein. The strain energy release rate approach was unable to accurately correlate the data for two of the three laminate families as the data clearly showed that the critical value of strain energy release rate is significantly dependent on the effective ply thickness. The Quadratic Delamination Criterion, an average stress criterion which involves the comparison of the calculated interlaminar normal stress and interlaminar shear stress ([sigma]1z) to their related strength parameters, is proposed and shows excellent correlation with the delamination initiation stress data.

This book was released on 2013 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectiveness of shifting the failure mode away from delamination by the installation of multiple fasteners in series which arrests and stabilizes mixed mode interlaminar failure in composite structures has been demonstrated through analytical and experimental investigation. Based on the novel mixed mode axially loaded specimen, a multi-fastener specimen was manufactured using a quasi-isotropic layup. Testing showed that the damage tolerance of the structure was improved by the inclusion of a second fastener in the crack arrest feature, with laminate failure occurring before significant delamination propagation past the second fastener. Concurrently, finite element models were developed with good agreement of the results. Parametric studies were performed which aid in the optimization of the feature by studying the relative effect of various parameters such as fastener spacing and stiffness as well as laminate thickness and layup. Additional modeling investigated the crack curvature caused by the installation of a fastener, and the possibility of modeling the system with one dimensional elements. It is recommended that the finite element solution be used to aid in the design of alternate specimen configurations which would increase the crack length prior to total laminate failure.
