我們如何通過万能试验機幫助客戶將研發時間縮短30%-我們與新能源汽車製造商的碳纖維測試故事

去年春天,我們的銷售經理老陳接到了一個緊急電話,來自國內一家領先的新能源汽車製造商材料研發部的張工聽起來非常焦急:“我們已經開發了三個新版本的車身碳纖維複合材料配方,但每次測試,數據都不穩定。項目已經推遲了兩個月。如果我們不能很快解決這個問題,今年的量產計劃將不得不推遲。”原來他們被卡住了。

張工和他的團隊有一個明確的目標:用碳纖維複合材料取代傳統的鋼材,將車身重量減輕15%,從而增加續航里程。這是他們新車型的核心賣點。但無論他們如何測試,都有些不對勁:

-在同一批樣品上使用他們的舊設備會得到五種不同的結果,數據偏差高達2%。研發團隊根本無法根據如此不可靠的數據做出決策。

――碳纖維複合材料是通過漸進開裂失效的。舊設備採樣速度慢,無法捕捉到中間損壞過程。他們只知道它最終什麼時候破裂,不知道爲什麼。

――最頭疼的是夾住樣品。它們會在拉伸時滑倒,有時夾具會在樣品破裂前鬆動,浪費大量時間。實驗室技術人員已經筋疲力盡了。

平心而論,這不是他們的錯。許多從事新材料研發的人都遇到過這個問題:設備參數在紙上可能看起來很相似,但對於高精度測試來說,微小的差異很重要。

我們的定製解決方案實際上只改變了兩件事:

聽完張工的要求,我們爲他們提供了一臺50kN電腦控制的電子萬能試驗機,對碳纖維測試進行了兩項具體調整:

1)定製氣動夹具。普通扁平握把無法夾住光滑的碳纖維樣品,導致滑脫。這個問題立即得到解決。同批次樣品的測試偏差控制在0.3%以內,提供了更穩定的數據。

2)採樣頻率升級至10000赫茲,舊設備每秒只採集100個點,遺漏了整個裂紋擴展過程,每秒10000個樣本,完整記錄了完整的失效過程曲線,讓研發看到了每一步的變化,結果比我們預期的還要好。

設備到達後的第二天,我們的工程師在現場進行了第一次測試,他們準備了三種不同碳纖維含量的樣品,每種類型有五個平行的樣品,從裝夾到生成報告,一切都在不到兩個小時的時間內完成。

張工和他的團隊盯着屏幕上的曲線看了許久,50%含量的樣品在1.2%的伸長率下顯示出了第一次損壞——這是他們的舊設備從未檢測到的一點!有了這個精確的數據,他們很快調整了配方,達到了55%的碳纖維含量。不僅抗拉強度達到了2350MPa,滿足了身體強度要求,重量也比原計劃額外減少了3%,超過了他們的性能目標。

客戶最終獲得的有形利益

在項目驗收過程中,張工告訴我們這臺機器幫了我們很大的忙:

1.研發速度明顯加快:過去需要一週測試而沒有結論的東西現在只需兩天就產生了一組可靠的數據。整個配方R&D週期縮短了30%,項目滿足了最初的量產計劃。

2、再也不用擔心質量問題:現在每一批進貨的碳纖維原料都可以快速抽檢,不合格的材料上門拒收,杜絕材料性能不穩定造成生產延誤。

3、顯著節約成本:配方優化後,碳纖維用量降低10%,每輛車的材料成本降低8%。僅原材料成本每年就節省了1000萬元以上。

張工開玩笑說,“我以前認爲測試機只是一個‘數據輸出工具’。現在我意識到,數據是否準確直接決定了一個項目的生死。”

我們真正關心的是爲客戶解決實際問題

做了這麼多年的電子萬能試驗機,我們很明白一件事:痛點跨行業差別很大;建築材料需要測試螺紋鋼強度以求安全;醫療器械需要測試植入物性能以挽救生命;新能源需要測試新材料以加速開發;許多小廠商只在價格上競爭,列出令人印象深刻的規格,但他們的設備在實際使用中卻充滿問題。

我們的設備始終堅持這些原則,通過幫助客戶測試瞭解到:

如今,我們的電子萬能測試機已深入到數十個行業——汽車、航空航天、建築、醫療等——幫助500多家客戶解決從R&D到生產的測試挑戰。如果您還面臨材料測試問題,如“數據不準確導致延誤”,請隨時與我們聯繫。也許合適的機器可以幫助您大幅推進陷入困境的項目。
