Fiber reinforced glass composites functional

Translucent sandwich panels for the side-facades were also made of glass-fiber-reinforced polyester composites (see Figure 1.8). The sandwich panels consisted of two layers separated by a composite fiber sheet with trapezoidal corrugations. The surface of the facade panels was finished with fleeces that also provide resistance to aging and U V radiation. As the main function of these facade elements was thermal insulation, the sandwich panels were filled with aerogels. They were therefore able to provide a K-value of 0.4 W m with a panel thickness of only 50 mm [18]. In terms of building fire considerations, a sprinkler system was installed as an active fire protection. [Pg.11]

A trend of CTE similar to the latter results was obtained by TMA measurements performed on the MWCNTs infused through and between glass fiber tows along the through-thickness direction [74]. Both pristine and functionalized MWNTs were used in fabricating multiscale glass fiber-reinforced epoxy composites. The CTEs of the resin and the resin-fiber system were tested by TMA with a ramp rate of 5 °C/min. [Pg.214]

There are many ways to classify composites, including schemes based upon (1) materials combinations, such as metal-matrix, or glass-fiber-reinforced composites (2) bulk-form characteristics, such as laminar composites or matrix composites (3) distribution of constituents, such as continuous or discontinuous or (4) function, like structural or electrical composites. Scheme (2) is the most general, so we will utilize it here. We will see that other classification schemes will be useful in later sections of this chapter. [Pg.101]

The axial and transverse tensile moduli for a continuous, unidirectional glass-fiber-reinforced epoxy matrix composite as predicted by Eqs. (5.88) and (5.92) are given as a function of volume fraction fiber, E/, in Eigure 5.87. Since Ef E, Eq. (5.92) reduces to the approximate expression ... [Pg.479]

A thermohardening composition for glass fiber reinforced plastics consists of PPO, BPA/DC and a bismaleimide [45]. Still higher heat resistance is achieved, if the poly-functional maleimide, based on aniline-formaldehyde condensation products (Scheme 11), is used [46]. [Pg.48]

Fibers having an aspect ratio of above 10, such as glass fibers, asbestos, wollastonite, cellulose fibers, carbon fibers, and whiskers, act as reinforcing agents. Composites may be classified into four groups, as shown in Table II. In modern composites, such as in the case of epoxy resins reinforced with carbon fibers (51). the polymer matrix has only a secondary function to separate the individual fibers from one another and to transfer energy to the fiber surface the fibers almost completely withstand the mechanical load. [Pg.232]

Kunz and Kirschning developed a chemically functionalized monolithic material which is based on a glass/polymer composite [28,29] (refer to Sect. 3.1). This material is available in different shapes including rods, disks, and Raschig rings. The polymeric phase of this composite was chemically functionalized (e.g., substitution of the benzylic chlorine by trimethylamine or sulfonation). Rod-shaped objects were first embedded in a solvent-resistant and shrinkable PTFE tube. This was followed by encapsulation with a pressure-resistant fiber-reinforced epoxy resin housing with two standard HPLC fittings, which created... [Pg.222]

Response surfaces showing the effects of composition on mechanical properties are compared with the compatibilized blend and the glass-fiber-reinforced composite in Fig. 5.7 and 5.8. Regression models for the compatibilized blends are shown below the response surface graphs (Fig. 5.7, a-e) versus reinforced (Fig. 5.8, a-e) blends shows a marked difference in the nature of the responses. Most notably, the curvature in the response observed in the compatibilized blends has vanished, and the response is a function of Kraton rubber only for the flexural modulus, notched Izod impact, and tensile strength. Similarly, the heat distortion temperature is now only a linear function of Kraton and HDPE levels. Finally, elongation at break has been reduced to a single value (3.43 0.45%), as more than 90% of the variability in the data was explained by the mean value. Thus,... [Pg.136]

Figures 12.9 and 12.10 are plots of heat capacity as a function of glass fiber content and temperature. These plots were based on data obtained by Karian (1) using DSC methodology to investigate glass fiber-reinforced composites of polypropylene.
