Available in PDF, EPUB and Kindle. Book excerpt: For uni-directional fibrous composites and laminated composites, a heat-balance integral method has been developed for the analysis of transient heat flow along the fibers or in the plane of laminates. The method is based on the construction of, for the two constituent media, temperature profiles which not only satisfy the necessary boundary conditions but also fulfill the asymptotic error function properties when inter-region conduction is vanishingly small or at very early times of the heat transient.

Available in PDF, EPUB and Kindle. Book excerpt: Transient heat flow in fibrous composites is important in determining the depth of heat penetration and temperature gradients near surface layers. A pervious report dealt with heat flow parallel to the fiber axis. This research is concerned with heat flow perpendicular to the uni-directional fibers. Temperature responses under the condition of a constant surface heat load are calculated by a finite-difference approach. The rise of the composite surface temperature is governed by two bounding-limits (the effective bound and the matrix bound) depending on the time scale. A threshold time criterion is established in this research which is based on a heat penetration concept.

Book Synopsis Conduction Heat Transfer Analysis in Composite Materials by : Lit S. Han
Download or read book Conduction Heat Transfer Analysis in Composite Materials written by Lit S. Han and published by . This book was released on 1980 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: With anticipated increased use of composite materials in aerospace structures and other applications, thermal properties of composites are needed as essential design information. In the past there was only scanty amount of research effort in thermal analysis of composites, as most of the work has been concerned with their mechanical properties. This report contains results from a rigorous analysis to determine steady-state effective thermal conductivities of fiber-matrix type of composites. The fibers bundled into twos are considered dispersed in a matrix of resin. The dispersion patterns of configurations considered are: (1) uni-directional fibers in a matrix, as the simplest geometry, and (2) 0.90 configuration in which two uni-directional tapes are overlaid at 90 degrees to each other. The method of analysis is to solve a two-region steady-state heat conduction equation either analytically or numerically. The analysis assumes a prior knowledge of the geometry of a composite and the constituents thermal conductivities.

Available in PDF, EPUB and Kindle. Book excerpt: Transient heat conduction experiments were performed on graphite- epoxy composites with fibers oriented uni-directionally in the matrix. With the fiber axis arranged parallel or transverse to the 4 heat flow direction, effective thermal conductivities and diffusiveities in the three orthogonal directions were obtained. also determined in this work were the isotropic conductivity and diffusivity for the epoxy resin (Fibrite No. 934) as 0.136 BTU/ hr-F-ft. and 8.5. x 10 to the 7th power sec, respectively. A value of k=6.0 BTU/ hr-F-ft for carbon fobers (Hercules 3501-5A) in the axial direction was deduced. For the conductivity transverse to the fibers, a value of 2.4 BTU/hr-F-ft was obtained from the measured effective transverse conductivity values. The thermal capacities (pC) for the carbon fibers and resin used in this study were determined as 48.2 and 44.4 BTU/cu ft 3-F, respectively.
