    摘要: A method of making a protective coating material wherein there is provided a matrix of melted polymeric material transparent to energy of a predetermined type and having a predetermined melting temperature. A fabric of polymeric fibers having a melting temperature higher than the melting temperature of the matrix is placed in the matrix. The fibers are thermoplastic and have a strength of at least about 0.5 GPa (70,000 psi) and an elastic (Young's) modulus of at least about 25 GPa (3.6.times.10.sup.6 psi) and said matrix has an elastic modulus in the range from about 0.2 to about 3.times.10.sup.6 psi. A pressure of from about 1000 to about 2000 psi is applied to the fabric disposed in the matrix and then the temperature is raised to about and at least the melting temperature of the fabric for about the minimum time required to cause consolidation of the fabric and the matrix. The consolidated fabric and matrix are then rapidly cooled to a temperature below the melting temperature of the fabric.

    摘要: A deformation calorimeter that serves to deform a sample material whose temperature changes as a function of the deformation. The temperature change causes heat to flow into the material or out, depending on the character of the deformation, to cause a pressure change in a gas in and around the material. An analyzing scheme is employed to relate the pressure change to the amount of heat evolved during sample deformation.
