There is. A general heat insulating material has a very small thermal conductivity of 0.1 kcal / mh ° C or less because it contains a large amount of fine voids inside, but the compressive strength is as small as 10 Kgf / cm 2 or less. However, it cannot be used in a place where a high compression load is applied, such as the heat press or the brake shim. Therefore, the conventional heat insulating materials have the contradictory properties that the one having high compressive strength is inferior in heat insulating performance and the one having excellent heat insulating performance has small compressive strength, and there is no material having both properties.

When the thickness of the woven or non-woven fabric used for the prepreg 1 is too thin, and when the thickness of the fiber layer 2 made of the woven or non-woven fabric is too thick, the matrix to the fiber layer 2 made of the woven or non-woven fabric The penetration amount of the resin liquid is insufficient, resulting in delamination and reduction in compressive strength.

When the density of the woven or non-woven fabric is low and the density of the matrix resin is high, the optimum matrix resin content is large, and in the opposite case, it is small.
As an example, using glass fiber as a woven or non-woven fabric,
When a phenol resin is used as the matrix resin, the optimum phenol resin content is preferably in the range of 10 to 25% by weight. If the matrix resin content is too low,
Delamination and strength reduction occur, and if the amount is too large, the amount of void portions 5 decreases, and the heat insulating performance deteriorates.

大きくなり、これ以上だと圧縮強度が低下する。The number of laminated layers of the prepreg 1 and the woven or non-woven fabric layer 2 is arbitrarily selected depending on the required product thickness and heat insulation performance. When obtaining products with the same thickness, it is preferable to stack a number of thin products to obtain a product with uniform thermal conductivity, which is preferable from the viewpoint of physical properties, but it has the drawback of increasing the price. Therefore, the number of stacked layers is appropriately selected. The range of the porosity due to the void portion 5 included in the fiber layer 2 of the laminate is 5% by volume to 25% by volume, preferably 1%.
It is 0% to 20% by volume. If it is less than this, the thermal conductivity becomes large, and if it is more than this, the compressive strength decreases.
