"Optical microscopy is one of the most valuable?but under utilized?tools for analyzing fiber reinforced polymer matrix composites. This hands-on instructional book covers everything; sample preparation, microscopic techniques, and applications. The power of optical microscopy to study the microstructure of these heterogeneous, anisotropic materials is illustrated with over 180 full color images."

"Advanced fibre-reinforced polymer (FRP) composites have become essential materials for the building of new structures and for the repair of existing infrastructure. Advanced fibre-reinforced polymer (FRP) composites for structural applications provides an overview of different advanced FRP composites and the use of these materials in a variety of application areas.
Part one introduces materials used in the creation of advanced FRP composites including polyester, vinylester and epoxy resins. Part two goes on to explore the processing and fabrication of advanced FRP composites and includes chapters on prepreg processing and filament winding processes. Part three highlights properties of advanced FRP composites and explores how performance can be managed and tested. Applications of advanced FRP composites, including bridge engineering, pipe rehabilitation in the oil and gas industry and sustainable energy production, are discussed in part four.

"Penelitian ini bertujuan untuk mengetahui pengaruh post-cure terhadap depth of cure DOC resin komposit serat dan membandingkan metode pengukuran DOC. Sembilan spesimen EverX Posterior warna A3 yang disinar dengan irradiansi 800-1000 mW/cm2 20 detik dibagi menjadi 3 kelompok: diukur setelah penyinaran dan setelah 24 jam post-cure dengan profil kekerasan Vickers; serta metode ISO 4049. DOC yang diukur setelah penyinaran dan setelah 24 jam post-cure 3,02 0,02 mm dan 3,93 0,03 mm; serta metode pengukuran ISO 4049 4,88 0,13 mm. Disimpulkan terdapat peningkatan bermakna DOC yang diukur setelah 24 jam post-cure, dan metode ISO 4049 menghasilkan DOC bermakna lebih tinggi dari profil kekerasan Vickers.
This study aims to identify the effect of post cure towards depth of cure DOC fiber reinforced composite and compare DOC measuring methods. Nine speciments of EverX Posterior shade A3 cured with light irradiation 800 1000 mW cm2 20s divided into 3 groups measured after curing and after 24 hours post cure with Vickers microhardness profile and ISO 4049 method. DOC that measured after curing and after 24 hours post cure are 3,02 0,02 mm and 3,93 0,03 mm and with ISO 4049 method 4,88 0,13 mm. It was concluded thatDOC measured after 24 hours post cure is significantly higher than immediately after curing, and ISO 4049 method produce significantly higher DOC than Vickers microhardness profile."

"Penekanan setelah impak merupakan salah satu parameter penting pada komposit dengan penguat serat sebagai material struktur. Penelitian ini bertujuan untuk memperoleh nilai tekan sesudah impak dan kerusakannya pada komposit epoksi-kevlar, epoksi-gelas dan epoksi-hibrid-kevlar/gelas. Spesimen komposit difabrikasi dengan metode hand lay-up dengan variasi energi impak yang diberikan adalah 4 J, 8 J dan 15 J. Pengamatan dengan Through Transmission Ultrasonic setelah impak menunjukkan bahwa kerusakan yang terjadi adalah delaminasi. Komposit terbaik ditinjau dari nilai kuat tekan yang tinggi dan ukuran delaminasi yang paling kecil. Dapat dikatakan bahwa nilai kuat tekan tertinggi adalah epoksi-gelas yaitu sebesar 119,85 8,31 MPa.
Compression after impact is one of important parameter of fiber reinforced composites as structural materials. This research aimed to obtain the values of compression after impact and their resulting damage on kevlar epoxy, glass epoxy, and kevlar glass epoxy hybrid composites. The composite specimens were fabricated by a hand lay up method. These materials were experienced impact energy with a variation of 4 J, 8 J, and 15 J. Observation by Through Transmission Ultrasonic showed that the type of resulting damage after impact was delamination. From this research, the highest compressive strength and the smallest delamination belongs to the glass epoxy composite, with the value of 119,85 8,31 MPa as the highest value of compression strength."

"High Performance Fiber Reinforced Cement Composites (HPFRCC) represent a class of cement composites whose stress-strain response in tension undergoes strain hardening behaviour accompanied by multiple cracking, leading to a high strain prior to failure. The primary objective of this International Workshop was to provide a compendium of up-to-date information on the most recent developments and research advances in the field of HPFRCC. Approximately 65 contributions from leading world experts are assembled in these proceedings and provide an authoritative perspective on the subject. Special topics include fresh and hardening state properties, self-compacting mixtures, mechanical behavior under compressive, tensile, and shear loading, structural applications, impact, earthquake and fire resistance, durability issues, ultra-high performance fiber reinforced concrete, and textile reinforced concrete.

"The use of fiber-reinforced polymer (FRP) composite materials has had a dramatic impact on civil engineering techniques over the past three decades. FRPs are an ideal material for structural applications where high strength-to-weight and stiffness-to-weight ratios are required. Developments in fiber-reinforced polymer (FRP) composites for civil engineering outlines the latest developments in fiber-reinforced polymer (FRP) composites and their applications in civil engineering.
Part one outlines the general developments of fiber-reinforced polymer (FRP) use, reviewing recent advancements in the design and processing techniques of composite materials. Part two outlines particular types of fiber-reinforced polymers and covers their use in a wide range of civil engineering and structural applications, including their use in disaster-resistant buildings, strengthening steel structures and bridge superstructures.
