    • Rigid foam boards (387) and alternating absorptive fibrous web sheets (390) are adhered to form core panels (385) or billets. Porosity is maintained in the webs for forming integral structural ties by absorbing resin applied to overlying sandwich panel skins. Beveled foam recesses (386) adjacent web edge portions form structural resin fillets (398), and protruding edge portion (388) form expanded connections to the skins. Core panels oriented with their webs crossing are layered with web sheets to form enhanced panels. Boards or core panels and web sheets arranged in inclined stacks form second core panels having webs intersecting panel edges or faces at acute angles. Boards of alternating different physical properties and web sheets are bonded to form reinforced panels having differing interior and exterior densities. Compressible foam panels are used in place of or with web sheets to make bendable core panels. Foam between web edge portions is recessed for bonding a settable material to the edge portions.
    • 刚性泡沫板(387)和交替的吸收性纤维网片(390)被粘合以形成芯板(385)或坯料。 通过吸收施加到覆盖的夹心板表皮上的树脂,在网中保持孔隙以形成整体结构。 与腹板边缘部分相邻的斜壁泡沫凹槽(386)形成结构树脂圆角(398),并且突出边缘部分(388)形成与皮肤的扩张连接。 以纸幅交叉取向的芯板与网片层叠以形成增强板。 以倾斜堆叠布置的板或芯板和网片形成第二芯板,其具有以锐角与板边缘或面相交的网。 交替的不同物理性质的板和网片粘合以形成具有不同内部和外部密度的增强板。 使用可压缩泡沫板代替或与网片制成可弯曲的芯板。 腹板边缘部分之间的泡沫凹入,用于将可固化材料粘合到边缘部分。
