Embodiment 1

[0080] Tetramethylcyclotetrasiloxane and linear vinyl-terminated polysiloxane DMS-V03 (MW500, DP5, Gelest Co., Ltd.) were blended at a molar equivalent ratio of 2:1 and mixed thoroughly with a vortex mixer. After impregnating the mixture with D-glass type glass fibers (Nittobo Co., Ltd. product 3313), the impregnated glass fibers were placed on a release glass substrate and left at room temperature for 24 hours until the viscosity increased. Then, the upper surface of the impregnated glass fiber was covered with another release glass substrate, the remaining resin was removed from the glass fiber with a laminator, and then thermally cured in an oven at 100°C for 4 hours, thereby producing a transparent silicone composite plate.

Embodiment 2

[0082] A silicone resin composite sheet was prepared in the same manner as in Example 1 except that DMS-05 (MW800, DP9, Gelest Co., Ltd.) was used as the vinyl-terminated polyorganosiloxane instead of DMS-V03.

Embodiment 3

[0084] A silicone composite sheet was prepared in the same manner as in Example 1 except that DMS-21 (MW6000, DP65, Gelest Co., Ltd.) was used as the vinyl-terminated polyorganosiloxane instead of DMS-V03.

Abstract

Disclosed herein is a composite sheet including a matrix and a reinforcing material impregnated in the matrix. The composite sheet has a weight variation (”W) of 98% or more at 350°C and a relaxation modulus of 1000 MPa or less under a load of 100 µN. The composite sheet suppresses the formation of a ring structure and thermal decomposition at temperatures of 350°C or more, thereby preventing a failure of the materials at high temperatures in the manufacture of a substrate.

Description

technical field [0001] The present invention relates to a composite board, its preparation method and a display substrate comprising it. Background technique [0002] Glass substrates have excellent heat resistance, transparency, and low linear expansion coefficient. Accordingly, glass substrates have been widely used as substrates for liquid crystal display devices, organic EL display devices, color filters, solar cells, and the like. However, glass substrates have limited suitability for thinner and lighter LCDs due to thickness, weight, and vulnerability to impact. In addition, glass substrates are not suitable for use as display substrates due to the brittleness of glass materials. [0003] Therefore, display substrates manufactured from plastic optical film materials have attracted attention in the art as an alternative to glass substrates. However, plastic optical film materials have a high coefficient of thermal expansion and are disadvantageous in terms of hardnes...
