The use of fiber reinforced plastic (FRP) composites for prestressed and non-prestressed concrete reinforcement has developed into a technology with serious and substantial claims for the advancement of construction materials and methods. Research and development is now occurring worldwide. The 20 papers in this volume make a further contribution in advancing knowledge and acceptance of FRP composites for concrete reinforcement. The articles are divided into three parts. Part I introduces FRP reinforcement for concrete structures and describes general material properties and manufacturing meth.

This book discusses how the excess value, of the products using braid, is captured in prosthetic limbs, aircraft and automotive components, commercial furniture, and trenchless sewer repair structures. It outlines the braided pultrusion process and also discusses impregnation states.

The recently promulgated ASTM D7522 Standard Test Method for Pull-Off Strength for FRP Bonded to Concrete Substrate provides a method for quality control and acceptance testing of fiber reinforced polymer (FRP) systems adhesively bonded to a concrete substrate. In the process of developing ASTM D7522, a number of comments and questions were received?some were incorporated as best practices and some were tabled, requiring further investigation. The present study addresses the latter issues and thereby directs future amendments of the ASTM D7522 standard method. Specifically, this study addresses the effects of specimen shape, the effects of variation in specimen cut depth, methods of cutting square specimens, and the impact of retesting specimens that do not fail during their initial test. It is shown that square specimens should be permitted although their results may not be directly compared with round specimens and they may have some other practical considerations affecting their use. Additionally, it is shown that cutting too deeply into the concrete substrate results in lower values of pull-off strength.
