Glass fiber compositions

Fig. 5. Interlaminar fracture toughness, for a number of thermosetting and thermoplastic composites (36,37). Open white bars represent glass-fiber composites shaded bars are for carbon fibers. The materials are A, polyester (unidirectional) B, vinyl ester (CSM = chopped strand mat) C, epoxy (R/BR1424) D, epoxy (T300/914) E, PPS F, PES and G, PEEK. To convert J/m to fdbf/in. multiply by 2100.

Several of these natural fiber composites reach the mechanical properties of glass fiber composites, they are already being used in the automobile and furniture industries. Up to now, the most important natural fibers were jute, flax, and coir. 

Again, Eqs. (28) and (48) form a system of two equations and two unknowns, which can be solved and yield the values of the exponents q, and q2. Their difference A=r 1— q2, which expresses the quality of adhesion, is called the adhesion coefficient. The values of the exponents q, and q2> as well as of their difference A were given in Table 2 and plotted in Fig. 15 for the glass-fiber composites given in Ref. 22).

We report herein LPD titania films deposited on three kinds of polyimides two high-temperature polyimide resins (PMR-15 and Kapton ) and a bismaleimide glass fiber composite (BMI). We have examined different solution conditions and different surface priming strategies. We have also learned to minimize film cracking by carefully controlling the drying process.

Glass fiber composites are the most common type of composite. However, graphite, aramide, and other reinforcements are finding applications in demanding aerospace functions and in premium sporting equipment such as fishing rods, tennis rackets, and golf clubs. 

For non-conducting fibers, such as glass, the matrix resin is the more conductive phase, at least early in cure, and one would expect some internal polarization effects to be visible in parallel-plate data. However, in spite of a large body of literature on glass fiber composites (see Sect. 5), we have found no clearly documented cases of Maxwell-Wagner effects in fiber-reinforced composites. We speculate that...
