Book Synopsis Fiber-Reinforced Composite and Wood Bonded Interfaces by : JF. Davalos
Download or read book Fiber-Reinforced Composite and Wood Bonded Interfaces written by JF. Davalos. This book was released on 2006. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-reinforced plastic (FRP) composites have shown the potential for reinforcement of wood structures (e.g., bonding of FRP strips or fabrics to wood members). Although significant increases in stiffness and strength are achieved by this reinforcing technique, there is a concern about the reliable performance of the FRP-wood adhesive bond, which is susceptible to delamination. The overall objective of this two-part paper is to develop a qualification program to evaluate the service performance and fracture of composite/wood bonded interfaces. Two types of FRP-wood interfaces are studied: phenolic FRP-wood and epoxy FRP-wood bonds. In the present paper, Part 1, the durability and shear strength of FRP-wood bonds are evaluated by modified ASTM tests. First, the service performance and durability of FRP-wood interface bond is evaluated using a modified ASTM delamination test. Then, the apparent shear strengths of bonded interfaces under both dry and wet conditions are obtained from modified ASTM block-shear tests. It is shown that the modified ASTM D 2559 standard test can be successfully used to study the effect of several parameters (e.g., bonding pressure, assembling time, and coupling agents) on bondline performance under wet-dry exposure cycles. Then for the best combination of parameters, the average interface shear strengths can be obtained from block-shear tests of ASTM D 905, modified for hybrid laminates. Mode I fracture of FRP-wood bonded interfaces and guidelines for FRP-wood bond performance evaluation are presented in the companion Part 2 paper.

Book Synopsis Long Term Durability of Structural Materials by : P.J.M. Monteiro
Download or read book Long Term Durability of Structural Materials written by P.J.M. Monteiro. This book was released on 2001-08-29. Available in PDF, EPUB and Kindle. Book excerpt: "Long Term Durability of Structural Materials" features proceedings of the workshop held at Berkeley, CA in October, 2000. It brought together engineers and scientists, who have received grants from the initiative NSF 98-42, to share their results on the study of long-term durability of materials and structures. The major objective was to develop new methods for accelerated short-term laboratory or in-situ tests which allow accurate, reliable, predictions of the long-term performance of materials, machines and structures. To achieve this goal it was important to understand the fundamental nature of the deterioration and damage processes in materials and to develop innovative ways to model the behavior of these processes as they affect the life and long-term performance of components, machines and structures. The researchers discussed their approach to include size effects in scaling up from laboratory specimens to actual structures. Accelerated testing and durability modeling techniques developed were validated by comparing their results with performance under actual operating conditions. The main mechanism of the deterioration discussed included environmental effects and/or exposure to loads, speeds and other operating conditions that are not fully anticipated in the original design. A broad range of deterioration damage, such as fatigue, overload, ultraviolet damage, corrosion, and wear was presented. A broad range of materials of interest was also discussed, including the full spectrum of construction materials, metals, ceramics, polymers, composites, and coatings. Emphasis was placed on scale-dependence and history of fabrication on resulting mechanical behavior of materials.

Book Synopsis Effect of Moisture on Fracture Toughness of Composite/Wood Bonded Interfaces by : BS. Trimble
Download or read book Effect of Moisture on Fracture Toughness of Composite/Wood Bonded Interfaces written by BS. Trimble. This book was released on 2000. Available in PDF, EPUB and Kindle. Book excerpt: Current research on wood reinforcement has focused on the use of fiber-reinforced plastic (FRP) strips or fabrics bonded to wood members. Although significant increases in stiffness and strength have been achieved by this reinforcing technique, there is a concern about the reliable performance of the wood-FRP interface bond, which can be susceptible to delamination. The objective of this study is to present a combined analytical/experimental study to evaluate the effect of moisture on fracture toughness of composite/wood bonded interfaces under Mode I loading. A contoured double cantilever beam (CDCB) specimen is used to characterize the fracture toughness of both wood-wood and wood-FRP samples. The specimens are designed by the Rayleigh Ritz method to achieve a linear rate of compliance with respect to crack length and are calibrated experimentally and also analytically by the finite element method. Both wood-wood and wood-FRP samples are tested under dry and wet conditions, and bonded interface fracture toughness data under Mode I loading are obtained. The guidelines and procedures for the modeling and design of CDCB specimens for hybrid or dissimilar adherends using a Rayleigh-Ritz model are presented briefly, and a modified Rayleigh-Ritz method is further developed. The effect of moisture on fracture toughness is evaluated, and increases in interface fracture toughness are observed due to moisture absorption for wet wood-wood and wood-FRP samples; the toughening of the interface under moisture is due mainly to a much more plastic fracture failure mode of the interface.
