Abstract: The composite pultruded products either in "I" profile or "Plate" profile of higher cross sectional area where said products consisting essentially synthetic polyester felts as core impregnated with a resin system comprises of at least one resin, curing system comprising a curing agent and an accelerator, a filler, a thinner, pigment or any other additives; encapsulated between bi-directionally and / or uni-directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with said resin system are provided. In another composite pultruded products either in "I" profile or "Plate" profile of higher cross sectional area where said products consisting of plank of short fibers bagasse premixed with the said resin system as core is enclosed between the synthetic polyester felts impregnated with the resin system which is further enclosed between bi-directionally and / or uni- directionally oriented synthetic fabric selected from polyester, carbon, aramid, glass, basalt and mixtures thereof impregnated with the resin system. The system and method for the preparation of said composite pultruded products are also illustrated herein. These products lead to a significant reduction in weight and reduction in density with higher stiffness and bending strength. The present composite products are encapsulated by fabrics in the peripheral area bringing more integrity uniformity of synthetic polyester felt materials. This leads to a significant cost reduction without sacrificing much tensile strength.

Abstract translation: 具有较高截面积的“I”型材或“板材”型材的复合拉挤制品，其中所述基本上由合成聚酯毡作为浸渍有树脂体系的芯材的产品包含至少一种树脂，固化体系包含固化剂和 促进剂，填料，稀释剂，颜料或任何其他添加剂; 提供了在选自聚酯，碳，芳族聚酰胺，玻璃，玄武岩以及浸渍有所述树脂体系的其混合物的双向和/或单向取向的合成织物之间封装。 在另一种具有较高横截面积的“I”型材或“板材”型材的复合拉挤制品中，所述由短纤维甘蔗渣板材与所述树脂系统预混合为核心的所述产品封装在浸渍有树脂的合成聚酯毡之间 系统，所述系统进一步封闭在双向和/或单向取向的合成织物之间，所述合成织物选自浸渍有树脂体系的聚酯，碳，芳族聚酰胺，玻璃，玄武岩及其混合物。 这里还说明了用于制备所述复合拉挤产品的系统和方法。 这些产品通过更高的刚度和弯曲强度显着降低重量并降低密度。 目前的复合产品在周边区域由织物封装，使合成聚酯毡材料具有更高的完整性。 这导致显着的成本降低而不牺牲许多拉伸强度。
