摘要： A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam may be any polymeric material which is capable of being foamed. Distributed substantially evenly throughout the foam is a mat of long glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long glass fibers with a foam-forming mixture, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture therebetween through means for metering the amount of foam-forming mixture and causing it to fully penetrate between the fibers of said glass mat.

摘要： A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam is characterized in that the major recurring chemical linkage therein is the isocyanurate moiety. Distributed substantially evenly throughout the foam is a mat of long straight glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long straight glass fibers with a foam-forming mixture of an organic polyisocyanate and a diol, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture there between through the nip of two rotating rolls.
摘要翻译： 结构层压板包括至少一个具有刚性泡沫的面向平面的片材，其附着在相对片材的一个表面上。 硬质泡沫的特征在于其中主要的重复化学键是异氰脲酸酯部分。 基本上均匀地分布在整个泡沫中的是长度为直的玻璃纤维的垫，其基本上平行于相对的片材布置成层。 用于生产该结构层压体的方法包括以下步骤：将长直的玻璃纤维的薄的，基本上不可压缩的可膨胀垫与有机多异氰酸酯和二醇的泡沫形成混合物接触，将面层片定位在垫的每个表面上， 并且通过两个旋转辊的辊隙将具有垫和其中的泡沫形成混合物的表面片材通过。
