    摘要： The present invention relates to a prepreg including an insulating resin composition impregnated into a substrate including a fibrous material and a porous support, and a printed circuit board including the same as an insulating layer.According to the present invention, it is possible to improve fire resistance, reduce weight, and reinforce mechanical characteristics by using a mixture of the fibrous material and the porous support as the substrate used for impregnation of the insulating resin composition and disposing the porous support around the fibrous material. Further, it is possible to reinforce local/overall strengths, facilitate manufacture of the product, increase resistance to bending stress, aseismatic, fireproof, and durable types, and secure improvement in a coefficient of thermal expansion by combining the porous support and a base resin and disposing the fibrous material in a main structural part which receives a force.

    摘要： Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 2.5 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds. All coatings, in particular elastomeric, non-silicon coatings, and coated airbags, meeting these criteria are intended to reside within the scope of this invention.

    摘要翻译： 提供涂覆的充气织物，更具体地说，已经施加了非常低附加量的涂层的安全气囊，其显示出非常低的透气性。 本发明的织物主要用于需要低渗透特性的汽车约束垫（例如侧帘安全气囊）中。 传统上，已经使用诸如氯丁橡胶，硅酮等化合物的沉重且因此昂贵的涂层来提供所需的低渗透性。 本发明的织物使用廉价的非常薄的涂层来提供这种必需的低渗透性水平。 因此，本发明的涂覆的气囊具有每平方码最多2.5盎司的涂层，最优选约0.8盎司/平方码，并且显示出泄漏时间（测量在该内部气体中引入的全部气体所需的时间 至少7秒钟，气囊在膨胀期间处于峰值压力，以10psi逃离安全气囊）。 满足这些标准的所有涂层，特别是弹性体，非硅涂层和涂覆的安全气囊旨在在本发明的范围内。
