Intraply

The time needed for polymer chains of amorphous thermoplastics above Tg and semicrystalline thermoplastics above Tm to diffuse across the interface and randomize is relatively short compared with the time needed for resin flow. It is believed, therefore, that diffusion bonding is completed immediately after the two molten surfaces merge, and that the microstructure of the contact zone is also assumed to be identical to that of the intraply sections [12,13],... [Pg.212]

Plastic composite mechanics in conjunction with structural mechanics can be used to derive explicit equations for the structmal response of simple structural elements. These explicit expressions can then be used to perform parametric studies (sensitivity analyses) to assess the influence of the hybridization ratio on structural response. For example the structural response (behavior variables) equations for maximum deflection, buckling load and frequency of a simply supported beam made from intraply hybrids are summarized in Figure 6.7 Flexural modulus is used to determine the maximum deflection, buckling load, and frequency of a simple supported beam made from intraply hybrids. [Pg.504]

Introductory approaches have been described to formally evaluate design concepts for select structural components made from composites including intraply hybrid composites and strip hybrids. These approaches consist of structural analysis methods coupled with composite micromechanics, finite element analysis in conjimction with composite mechanics, and sensitivity analyses using structural optimization. Specific cases described include ... [Pg.513]

Surface shear angles and material draw-in have been optically measured by the use of a camera. The intraply shearing effects can be measured by the in-plane shear angle and seems to be the most important deformation mode of textile composite. [Pg.278]

Inter-fiber (intraply) shear occurs when the fibers rotate about the stitches or weave centers. [Pg.273]

With RPs there can be the intraply hybrid composites have two kinds of fibers embedded in the matrix in general with the same ply providing different orientation performances. They have evolved as a logical sequel to conventional composites and to interply hybrids. Intraply hybrid composites have unique features that can be used to meet diverse and competing design requirements in a more cost effective way... [Pg.295]
