Description

纤维复合材料制作方法 技术领域
本发明涉及一种纤维复合材料制作方法，详指应用于纤维制作领域的技术，其主要技术特征在于减少纤维材料在制作上的工序，而在减少工序下更可以达到节省成本及环保。
背景技术
复合纤维是指由两种或两种以上高聚物，或具有不同分子量的同一高聚物经复合纺丝法制成的化学纤维。又，复合纤维以一定的方式沿纤维轴向复合而成的纤维。这类纤维可集多种成分的优点于一身，如涤/锦复合纤维，它既具有锦纶耐磨性好、高强、易染、吸湿的优点，又具有涤纶弹性好、模量高、织物挺硬等特点。随着人们生活水平的提高和环保意识的增强，消费市场出现了对高感性化、高功能化纺织品的需求。为因应这些需求，必须对传统的纤维制造进行变革，进而利用高功能纤维、高感性纤维、智能纤维以及可降解纤维等进行制作，以提高纺织品的科技含量和人们的生活质量。复合纤维的开发则是实现纤维高感性化、高功能化的一个重要手段。它可以通过喷丝板形设计、聚合物的配选设计以及纺丝纤维的截面设计等多种方式，获得各种性能、风格的新型纺织材料。
复合纤维作为一种具有特殊风格和性能的纤维品种，已广泛应用于人们的生活、工业、医疗、光电通信等领域，成为一种不可缺少的纤维材料，又因复合纤维织物正以其细致精巧的风格、柔软丰满的手感、良好的悬垂性、覆盖性、耐磨性、吸湿性、丝质感以及华丽的外观、独特的光泽迎合了人们对高档服饰的追求，还有在现今最流行的自行车领域里也流行复合纤维的使用，一般来说纤维复合材料的制作方法皆以预浸布的形式(混以热固性基材)或(热塑性基材)经裁切预浸料的外型，再将形料堆栈或贴合成工件雏形后，以模具加热加压塑形，等待一定时间后固化成形，接着将固化后的制成品由模具内取出后，再对制成品进行外观的再加工步骤，所谓再加工的工序包含有补土、研磨、涂抹金油、贴标签(LOGO)等，而一般以复合纤维制成成品的方法有很多，像是热冲压、模具内吹气成型、真空成型、吸塑法或是手工方式逐层堆栈等方法，但是基材于加热固化时流动或流平不足，造成于外观瑕疵缺陷孔隙产生而需要后制加工修整表面，如此才能够将商标及金油予以贴覆、涂抹。
上述所说是现今复合纤维的制作，可是在这科技飞跃的时代里，此种方法的步骤过于繁杂，且过多的方法只是造成人力上的消耗与浪费而已，甚至在后续的加工步骤里容易产生特殊化学物质，或者是必须使用到特殊的物料等，导致环境污染的环保问题产生，严重影响生态环境以及人类的生存质量。故，相关领域的业者必须以非常严肃的态度来审视此问题及缺失的发生。
技术问题
现有技术中复合纤维的制作方法的步骤过于繁杂，且过多的方法只是造成人力上的消耗与浪费而已，甚至在后续的加工步骤里容易产生特殊化学物质，或者是必须使用到特殊的物料等，导致环境污染的环保问题产生，严重影响生态环境以及人类的生存质量。
技术解决方案
为了解决上述技术问题，本发明提供一种纤维复合材料制作方法，其方法包括下列各步骤：预备制作料件：备置一裁切装置及多个纤维片，以该裁切装置切割各纤维片并形成多个工件预备料，并将多个工件预备料相互堆栈或贴合形成一工件雏品；外衣披覆：在工件雏品的外表面披覆一表面料片形成一工件半成品；置模塑形：将披覆有表面料片的工件半成品置入一模具内进行加热加压，并经过一定时间后固化成形；出品成形：该表面料片系整齐的完整披覆于工件半成品的外表面而形成一工件成品。
根据前述所说明的主要技术下，更进一步的技术特征在于，该至少一表面料片进一步披覆于工件雏品的内表面。
根据前述所说明的主要技术下，更进一步的技术特征在于，在该表面料片披覆于工件雏品的相反面进一步增设有一图签片，该图签片系为贴标、图纸、贴纸或是填料，又该图签片系与工件半成品、表面料片一同进入模具内进行加热加压。
根据前述所说明的主要技术下，更进一步的技术特征在于，在出品成形步骤的后进一步多一道后置加工步骤，后置加工步骤系在工件成品固化后，在该至少一表面料片的外周面进一步进行金油烤漆、贴标或涂附有填料。
有益效果
本发明提供的纤维复合材料的制备方法：制作者在进行复合纤维的时候，能够免去制品在出模具后还必须进行再次加工的工序，且连带能够节省过多人力的使用而避免无谓的浪费，另外已经免去再次加工的工序下，更能够免去任何化学材料的使用而达到环境保护的目的。本发明能够改善现有复合纤维材料在制作过程中，因制作后容易产生瑕疵而必须再次加工的工序，导致人力成本的浪费；且再次加工的工序容易因须使用到特定的化学料件而导致环境污染的问题发生。

本发明的实施方式
有关本发明所采用的技术、手段及其功效，举一较佳实施例并配合图式详细说明于后，相信本发明上述的目的、构造及特征，当可由的得一深入而具体的了解。以下以较佳实施型态说明，且并非对本发明作任何形式上的限制。
参阅图1至图7所示，本发明一种纤维复合材料制作方法，其方法包括下列各步骤：预备制作料件S1：备置一裁切装置1及多个纤维片2，各纤维片2为片状体，将各纤维片2量取所要制作的规格，例如要制作脚踏车座管、车壳等，再以该裁切装置1切割各纤维片2并形成多个工件预备料3，并将多个工件预备料3相互堆栈或贴合形成一工件雏品4，制作者可以根据所制作的物品而调整纤维片2的堆栈、贴合数量，或者是在备置纤维片2时就选择不同厚薄的规格进行裁切；外衣披覆S2：在工件雏品4的外表面披覆一表面料片5形成一工件半成品6；置模塑形S3：将披覆有表面料片5的工件半成品6置入一模具7内进行加热加压，并经过一定时间后固化成形，使表面料片5能够完全披覆于工件雏品4，不会有任何气泡、瑕疵、孔隙的产生；出品成形S4：待工件半成品6经模具7的加压加热后固化呈形，该表面料片5整齐的完整披覆于工件半成品6的外表面而形成一工件成品8；其中，将表面料片5于工件半成品6在加热加压前进行组合，使得工件成品8的外表面形成平整且亮丽。
请参阅图1的流程，以及图2至图7的各步骤的工序示意图，制作者根据上述的步骤下，先准备些许的纤维片2、表面料片5、裁切装置1及模具7即可，接着将各纤维片及表面料片5进行量 测，根据所要制作的对象以裁切装置1进行表面料片5及各纤维片2的裁剪，例如制作自行车车管、车盖壳等，按照所量测的大小而进行剪裁，再先把各纤维片2进行堆栈及贴合，制作者可以随此次所要制作的对象而调整所要堆栈、贴合的数量，又或者是在准备纤维片2时就先挑选不同厚薄的规格使用，然后在堆栈、贴合设置上根据所须而迭合不同尺寸的纤维片而各种堆栈、贴合的形态则不多加限制与赘述，当各纤维片2堆栈、贴合完成的后即可形成工件雏品4。接着将刚才同样准备完成的表面料片5披覆于工件雏品4的外表面，该表面料片5的披覆使其形成工件半成品6，准备完成后即可将工件半成品6置入一模具7内进行加压加热，表面料片5经过加压加热后会逐渐收缩而紧密的贴合于工件雏品4的表面，如此一来当工件半成品6经过模具7的加热加压后，并等待一定时间的冷却固化，接着由模具7退模后即可形成工件成品8，此工件成品8的外表面呈现平滑、亮丽、无凸起处、无凹洞处、无缺陷孔隙等，此方式的制作大幅缩减了制作的步骤以外，免除了像现有技术还须后续的加工，例如补土、研磨、修整等工序，如此一来就节省了大量的人力成本，且现有后续工序中研磨或是其他工序必须使用道化学物品，本发明省去了后续的加工工序下也可避免使用道化学物品而保护环境；不仅如此，表面料片5的设置更可以提升纤维片2的耐撞力以及抗撕裂性，使其由纤维片2所制作而成的对象都具有极高的耐用度，延常对象的使用性。
而纤维片2的使用大多数应用在自行车领域较为常态，因此现以脚踏车的车管为举例说明，脚踏车车管为了配合骑乘因此都是以圆柱为多数，故具有内外二表面，因此在制作脚踏车车管时，可以连同内表面也进一步披覆有表面料片5，请参阅图7所示，让整体车管不论是内外表面都平整；另外市面上常见的脚踏车车管上会设置有相关的图样、LOGO等，在现有技术上图样与LOGO的设置是必须通过后续加工的工序才可以制作，但是本发明可将图样、LOGO等贴标或者是填料等先于外衣披覆S2步骤前先进行操作，制作者可以将图样、LOGO等贴标或是填料先设置在表面料片5披覆于工件雏品4的相反面，使得表面料片5的外表面形成一图签片9，接着再将表面料片5披覆于工件雏品4的外表面形成工件半成品6，接着在一同放入模具7内进行加压加热，如此一来可以让图签片9与表面料片5更佳的密合又该图签片9的设置亦可于表面料片5披覆于工件雏品4的一侧，图未示，请参阅图1所示。
最后，虽说本发明主要的技术特征在于免去了后续的工序而减少人力上的支出，且图签片9设置步骤可以在表面料片5披覆工件雏品4前先设置，但是有些制作者对于后续的图样须进行增加、修饰等，因此可以于工件成品8完成再增加一后置加工S5步骤后再次进行图签片9的设置工序，请参阅图1所示并以图8为辅助，这对于制作过程来说并不会像现有般产生过多人力上的成本支付，也不会造成环境污染等问题，更重要的是后置加工S5步骤可有可无，完全取决于制作者对于工件成品8的外型是否可行，因此本发明不论是先进行图样、LOGO的贴年还是工件成品后的加工， 比起现有技术来说都显得更为省人力成本，也可以确实保护环境避免遭受污染，请参阅图1所示，图1中从后置加工S5步骤所链接的顺序可以二选一，其一为先与表面料片5一同披覆于工件雏品4，或者是其二的工序则是工件成品8完成后的再加工。
