作為復(fù)合材料填料領(lǐng)域的領(lǐng)導(dǎo)者，3M 公司推出了其新型Glass Bubbles S32HS空心玻璃微珠產(chǎn)品，以幫助原始設(shè)備制造商將復(fù)合材料部件重量減輕40%，密度低于1.0 g / cc ，同時仍然能夠完成A級的噴漆表面光潔度�！斑@項創(chuàng)新使SMC成為原始設(shè)備制造商進行汽車設(shè)計的一個有吸引力的選擇�！痹摴緢蟾�。 由于汽車制造商希望提高電氣化的燃料經(jīng)濟性和電池容量，因此不影響機械完整性的材料輕量化至關(guān)重要。即使是重量輕的金屬，也可能會帶來間接加工和制造成本，并且隨著全球金屬供應(yīng)的不確定性可能變得更加昂貴。在某些應(yīng)用中，片狀模塑料(SMC)是金屬的可行替代品，同時仍能達(dá)到所需的物理性能。 “隨著電動汽車和高效汽車的發(fā)展趨勢，降低汽車整體重量是保持競爭力的關(guān)鍵，”3M汽車電氣化部門副總裁Ray Eby說，“典型的汽車大約有660磅復(fù)合部件。使用了我們的空心玻璃微珠填料的超輕SMC，原始設(shè)備制造商可顯著提高車輛的能源使用率，同時節(jié)省資金�！� 多年來，3M公司一直與汽車行業(yè)合作，為主要汽車制造商實現(xiàn)輕量化。通過替代傳統(tǒng)的填料，這些空心玻璃微珠可以減少模制部件的重量并且不犧牲強度或美觀。該公司表示，3M公司第一次打破了密度障礙，使超輕型SMC比鋼鐵和鋁材方面更具競爭力，為汽車應(yīng)用中的材料組合開創(chuàng)了新的可能性。 “我們的客戶不斷要求我們降低玻璃纖維增強材料系統(tǒng)的密度和重量，以支持其汽車輕量化工作，”Core Molding Technologies公司的營銷和銷售副總裁Terrence O‘Donovan說，“達(dá)到1.0克/立方厘米或更低的密度，同時能夠保持A級表面一直是一個目標(biāo)。使用3M空心玻璃微珠可幫助我們滿足客戶的期望�！� 3M空心玻璃微珠是可用于輕質(zhì)密封劑、注塑件和SMC的輕量化技術(shù)。 Additive used for density reduction in sheet and bulk molded composite vehicle parts Helps reduce weight of composite parts by up to 40 percent with a density below 1.0g/cc Allows greater density reduction at lower filler loadings to maintain composite strength Enables parts with Class A paintable finishes Details Additive used for density reduction in sheet and bulk molded composite vehicle parts Helps reduce weight of composite parts by up to 40 percent with a density below 1.0g/cc Allows greater density reduction at lower filler loadings to maintain composite strength Enables parts with Class A paintable finishes Can significantly help improve fuel economy and extend electric vehicle battery range Spherical shape and moderate hardness help reduce production equipment wear Enables production of ultra-lightweight composite parts that may offer a lower cost alternative to aluminum in many applications 3M™ Glass Bubbles S32HS are performance enhancing polymer additives used to create ultra-lightweight parts with Class A paintable finishes in the automotive， marine， heavy truck and aerospace industries. When used as a filler in sheet or bulk molded composites， our glass bubbles can help reduce final part weight by up to 40 percent without compromising mechanical integrity.
Glass Bubble Benefits 3M™ Glass Bubbles S32HS offer a number of competitive advantages over traditional polymer fillers like silica， calcium carbonate， talc or clay. By replacing conventional fillers， these hollow glass microspheres can help reduce the weight of molded parts by up to 40 percent. With a density of 0.32 g/cc and an isostatic crush strength of 6，000 psi， 3M glass bubbles S32HS are great for customers looking to reduce composite density below 1.0 g/cc without sacrificing mechanical integrity or surface aesthetics. Furthermore， the unique spherical shape of our glass bubbles allows for higher volume loading while maintaining workable viscosity and contributes to the production of Class A paintable surfaces.
A Lighter Future A typical automobile has about 300 kg (661 lbs) of composite parts that contribute to vehicle weight. With electric and high efficiency vehicles becoming more popular， reducing that weight is the key to staying competitive. By integrating our glass bubbles into their sheet and bulk molded composite parts， customers can significantly improve a vehicle’s fuel economy or battery range. In some cases， using ultra-light composite parts may even be more cost effective than aluminum in the right applications. |
