Composite manufacturing

For improving the phase homogenization prior to hot pressing, some researchers prepared suspensions containing nanoparticles firstly. The typical procedures have been described in a series of works on PEEK composites by Xue et That is, the polymer powder (100 /xm) was fully mixed with the [Pg.549]

Accordingly, Schadler et al. employed a high-velocity oxy-fuel (HVOF) system to thermally spray Si02 (7 and 12nm)/nylon 11 nanocomposite coatings. Polymerization filling (i.e. monomers polymerized in the presence of fillers) is an effective approach to ensure intimate contact between the fillers and the matrix. Cai et al. synthesized carbon nanotube/polyimide (PI), nano-Al203/ [Pg.550]

We have proposed a multivariable regression approach for the estimation of ultrasound attenuation in composite materials by means of PE-measurements, thus overcoming the problem of limited access that is the main weakness of XT testing. Estimating the attenuation is a step towards determining the porosity contents, something that is of interest, for instance, in composite manufacturing. [Pg.892]

In the chemical engineering domain, neural nets have been appHed to a variety of problems. Examples include diagnosis (66,67), process modeling (68,69), process control (70,71), and data interpretation (72,73). Industrial appHcation areas include distillation column operation (74), fluidized-bed combustion (75), petroleum refining (76), and composites manufacture (77). [Pg.540]

The basic questions of The What, The Why, and The How of composite materials and structures have been addressed. Much more could be said about, for example, polymers, metals, ceramics, and carbon used as matrix materials. Also, many more composites manufacturing techniques are available. Moreover, many more examples of effective use of composite materials in structures do exist. However, an introduction to each topic has been provided, and hopefully, those introductions will suffice for the purpose of giving background on composite materials prior to studying their mechanics. [Pg.52]

Resin Socketing Compositions. Manufacturer s directions should be followed in handling, mixing, and pouring the resin composition. [Pg.594]

The composite manufacturing process was manually operated and inconsistencies due to the human factors required more conservative operating conditions. If the process was automated the process conditions would approach the optimal operating conditions predicted here. [Pg.269]

Okino etal. (2003) tested composites manufactured from acetylated rubberwood bonded with UF resin against G. trabeum and T. versicolor. In the 12-week exposure test, weight losses were found to considerably less than exhibited by control samples. [Pg.66]

Research on resin-bonded boards has used wood chips, or fibres, that are acetylated prior to composite manufacture. In almost all cases, acetylation has been achieved by using uncatalysed acetic anhydride. Significant improvements in dimensional stability proportional to the WPG of the wood particles have been reported when acetylated wood is used, and there is also a reduction in irreversible swelling (e.g. Bekere etal., 1978 Arora etal., 1981 Rowell etal., 1986a-e, 1989, 1990, 1991,1995 Yoshida etal., 1986 Youngquist etal., 1986a,b, 1988 Larsson and Tillman, 1989 Subiyanto etal., 1989 Vick etal., 1991 Clemons etal., 1992 Kajita and Imamura, 1993 Sasaki and Kawai,... [Pg.72]

Composite materials have been acclaimed as the Materials of the Future. A key question is whether composite materials will always remain the materials of the future or if the future is here. Advanced polymer composites, once destined for stealth military aircraft or aerospace uses, are beginning to be used in down-to-earth structures, such as bridges, buildings, and highways. However, there are still considerable impediments to wider use, and composite manufacturers need to make great strides in the development and manufacturing of composite materials. [Pg.19]

What makes the fabrication of composite materials so complex is that it involves simultaneous heat, mass, and momentum transfer, along with chemical reactions in a multiphase system with time-dependent material properties and boundary conditions. Composite manufacturing requires knowledge of chemistry, polymer and material science, rheology, kinetics, transport phenomena, mechanics, and control systems. Therefore, at first, composite manufacturing was somewhat of a mystery because very diverse knowledge was required of its practitioners. We now better understand the different fundamental aspects of composite processing so that this book could be written with contributions from many composite practitioners. [Pg.19]

This book provides a quick overview of the fundamental principles underlying composite processing and summarizes a few important processes for composite manufacturing. This book is intended for those who want to understand the fundamentals of composite processing. In particular, this book would be especially valuable for students as a graduate level textbook and practitioners who struggle to optimize these processes. [Pg.19]
