    Abstract: A circuit board having multiple layers of a dielectric material, multiple layers of a conductive metal and multiple layers of graphite bonded together to form a composite multilayer printed circuit board having a desired coefficient of expansion and having strip and microstrip transmission lines for electrically connecting very high frequency electronic components mounted on the circuit board. The multiple layers of graphite are positioned in a symmetrical manner with respect to the thickness of the circuit board and selected in number to provide the circuit board with a desired coefficient of expansion. In addition, at least some of the layers of graphite are positioned in close proximity to some of the layers of conductive metal to provide enhanced thermal conduction from the mounted components.

    Abstract: The invention relates to a method of making a composite laminate comprising the steps of providing unidirectionally oriented parallel fibres (UD filaments) (3) with a resin matrix to form a composite UD layer and laminating a plurality of UD layers to form a UD crossply laminate (18). In the method of the invention, the UD filaments are impregnated with a melt of a resin which in the uncured form solidifies below a certain temperature (Tm). Thereupon the UD filaments-containing resin is cooled to a temperature below Tm to produce said composite UD layer. The produced composite UD layer is irreversibly cured before or after lamination. Notably latent curing resins are suitable. The impregnation is preferably conducted by coating a process belt (8) with solid resin (6), laying the UD filaments onto the resin, and heating the resin so as to form the resin melt. The heating of the resin is preferably conducted by means of IR irradiation (11).

    Abstract translation: 本发明涉及一种制备复合层压材料的方法,包括以下步骤:用树脂基质提供单向取向的平行纤维(UD长丝)(3),以形成复合UD层并层压多个UD层以形成UD交叉层压 (18)。 在本发明的方法中,UD长丝用未固化形式的树脂熔体浸渍在一定温度(Tm)以下。 随后将含有UD长丝的树脂冷却至低于Tm的温度以产生所述复合UD层。 所制备的复合UD层在层压之前或之后不可逆地固化。 潜在的固化树脂是合适的。 浸渍优选通过用固体树脂(6)涂布处理带(8),将UD长丝铺设在树脂上并加热树脂以形成树脂熔体来进行。 树脂的加热优选通过IR照射进行(11)。
