Description

纖維板材的製作方法
本發明涉及一種纖維板材的製作方法及經該方法製得的纖維板材。
纖維被廣泛應用於航天航空、體育、電子產品等領域。習知技術，通常將纖維材料浸漬於環氧樹脂，以將環氧樹脂滲入纖維中，從而獲得力學性能優異的纖維板材。惟，該方法的耗時較長，良率較低。
鑒於此，提供一種耗時短、良率高的纖維板材的製作方法。
一種纖維板材的製作方法，其包括以下步驟：提供一脫模劑，將該脫模劑噴塗於模具的模腔中；將纖維布置入模腔中，所述纖維布具有複數通孔；將塑膠片置於所述纖維布的表面；對所述塑膠片進行烘烤處理，使得所述塑膠片熔融，處於熔融狀態的塑膠片部分滲入所述纖維布的所述複數通孔中，以排除所述複數通孔中的部分空氣；對所述纖維布、處於熔融狀態的所述塑膠片及滲入所述纖維布中的塑膠進行熱壓處理，以在纖維布的所述表面形成塑膠薄膜。
上述的纖維板材的製作方法操作簡單、耗時較短。由該纖維板材的製作方法所製得的纖維板材表面光滑、無氣孔，並具有較強的耐刮傷能力。

圖2係由本發明較佳實施例的纖維板材的剖視示意圖。
請結合參閱圖1與圖2，本發明一較佳實施方式的纖維板材的製作方法，其包括以下步驟：
步驟S1：提供一模具(未圖示)。該模具的模腔(未圖示)具有與一纖維布11相匹配的形狀和尺寸。該纖維布11具有複數通孔111。該纖維布11的材質可為熱塑性纖維，如碳纖維、玻璃纖維、或芳綸纖維等。該纖維布11的厚度為0.1~0.3mm。
步驟S2：提供一脫模劑。將該脫模劑噴塗於所述模具的模腔中，以利於脫模。
步驟S3：將所述模具加熱至模腔溫度為200~250℃後，將所述纖維布11置入所述模腔中。
步驟S4：提供一塑膠片(未圖示)，該塑膠片具有與所述纖維布11相匹配的形狀。該塑膠片的材質可為熱塑性聚氨酯(TPU)、或聚碳酸酯(PC)。
步驟S5：將所述塑膠片置於所述纖維布11的表面後，對該塑膠片進行烘烤處理，以熔化所述塑膠片。所述烘烤處理的步驟可為採用紅外光照射該塑膠片進行烘烤處理或採用電阻絲加熱該塑膠片進行烘烤處理。該烘烤處理於350~450℃的溫度下持續0.5~2分鐘，以熔化該塑膠片。處於熔融狀態的塑膠片部分滲入該纖維布11的通孔111中，並排除該通孔111中的部分空氣。可以理解的，也可於所述纖維布11的另一表面設置另一塑膠片，對所述二塑膠片進行烘烤處理，以熔化該二塑膠片。處於熔融狀態的二塑膠片部分滲入該纖維布11的通孔111中，並排除該通孔111中的部分空氣。
步驟S6：關閉模具，對所述纖維布11、處於熔融狀態的所述塑膠片及滲入所述通孔111中的塑膠進行熱壓處理。所述熱壓處理在壓力為40~60kg/cm2，溫度為200~250℃的條件下進行0.5~1分鐘。在所述熱壓處理的過 程中，所述處於熔融狀態的塑膠片於所述纖維布11相對的二表面或者一表面形成透明的塑膠薄膜13，所述通孔111中的塑膠形成連接所述塑膠薄膜13與所述纖維布11於一體的一連接層15，從而獲得所述纖維板材10。該塑膠薄膜13的厚度為0.1~0.3mm。所述熱壓過程中，通孔111中的空氣被排出至該纖維板材10的外部，使得該纖維板材10表面光滑、無氣孔。由於該纖維板材10的表面較光滑，且該模腔內噴塗有脫模劑，使得該纖維板材10較易脫模。
一種經由所述纖維板材的製作方法所製得的纖維板材10包括纖維布11、結合於該纖維布11相對二表面或者一表面的透明的塑膠薄膜13。該纖維布11具有複數通孔111，該通孔111被塑膠填充，從而形成連接該塑膠薄膜13與該纖維布11於一體的連接層15。
所述纖維布11的材質可為熱塑性纖維，如碳纖維、玻璃纖維、或芳綸纖維等。該纖維布11的厚度為0.1~0.3mm。
所述塑膠薄膜13的表面光滑，無氣孔。該塑膠薄膜13的厚度為0.1~0.3mm。該塑膠薄膜13的材質可為熱塑性聚氨酯彈性體(TPU)、或聚碳酸酯(PC)。
測試結果
採用百格刀對所述塑膠薄膜13的附著力進行測試，結果表明僅有0~4%的塑膠薄膜13脫落。
